Seiko Shogun Vs Sumo – Which Should You Go For?

Today we’re looking at the Seiko Shogun vs Sumo.

You know, of the many reasons we love Seiko, one of the top ones is the way they name their watches. Seiko just has the quirkiest names.  We’ve looked at Samurai, Turtle, Sumo, and today we will now be comparing the Shogun with the Sumo.

Both of these watches have a number of other models under them. But in this review, we will be zeroing in on one particular model of each of these watch lines – the SBDC029 for the Shogun and the SBDC033 for the Sumo.

These two watches belong to Seiko’s collection diver’s watches. And as usual, Seiko has delivered, with these watches, outstanding value for money.

Even if you don’t swim, talk more of dive, Seiko’s watches can help you make a statement when dressing for an outing or for work.

We hope you stay with us till the end of this review but if you can’t that’s okay. We already factored this in and prepared the “comparison overview” section to address such people. You’ll find it right after this section.

Alright, let’s get to down to the Seiko Shogun vs Sumo review without further ado.

Seiko Shogun Vs Sumo – Where Both Watches Get It Right

The most important aspect of these watches where Seiko does a splendid job is in their movement. The Seiko Shogun and Sumo both use an automatic movement which is kinda expected at its price.

The automatic movement Seiko uses here is the 6R15 and the 6R15 is a fantastic movement with loads of benefits.

First off, it is hackable which means that the second hand stops ticking as well when the crown is pulled full out.

Also, the movement comes with manual winding as well. This means that you can manually crank up your watch if it’s been in the drawer for a long time and you need to quickly head out.

Again, the 6R15 movement is great for its power reserve time. This movement reserves time for up to 50 hours after a single charge which is pretty impressive.

Finally, it also shows the day/date complication as well.

Other really great things about these two watches are its luminescent hands and markers great for seeing clearly under water. In fact, both watches meet the ISO 6425 standards totally and that’s fantastic to know.

In the end, the Seiko Shogun and Sumo are well-made watches well worth their price.

Seiko Shogun Vs Sumo – Where The Seiko Shogun Does Better

Primarily, in the Seiko Shogun vs Sumo debate, the Seiko Shogun does better in the quality of its bracelet. A titanium bracelet, of course, floors the stainless steel easily. It’s lightweight and quite resilient to many things even though it’s quite scratch-prone.

Also, the bracelet feels adequate in relation to the case of its host watch. This isn’t the case for the Seiko Sumo where the bracelet feels a little too inadequate to support the watch itself.

Besides the bracelet, the conservative and refined look of the Seiko Shogun is something the Seiko Sumo lacks. People with more conservative tastes would love the Seiko Shogun and to be honest, of the two watches, the Seiko Shogun is the more likely to be able to compete with the Rolex Submarine.

Seiko Shogun Vs Sumo – Where The Seiko Sumo Does Better

The primary advantage the Seiko Sumo has over the Seiko Shogun is its affordability. The Seiko Sumo is more affordable than the Seiko Shogun for obvious reasons. At least, for one, its bracelet is not made from a difficult-to-mill material. Stainless steel, on the other hand, is pretty easy to get so it doesn’t add to the cost of the watch.

Besides that, its winding feels a bit smoother than the Seiko Shogun. It winds smoothly and easily.

Finally, even though the Seiko Sumo doesn’t meet up to the Shogun in terms of quality, it is a dressy watch. This is something you can easily wear for a night out or any such outing. It’s not great for formal wear though.

Seiko Shogun Vs Sumo – Where Both Watches Don’t Get It Right

These two watches suck when it comes to their crystal. They smudge so easily and we’ve seen cases where the crystal cracked. You might want to change out the crystal from mineral to sapphire to ensure that your crystal lasts.

Also, both watches wear large which might be a con depending on the wearer. If you’re too slim especially you might find these watches a little too large for your wrist.

Finally, these watches do not have options for rubber straps which some might prefer to wear when diving.

Seiko Shogun Vs Sumo – Our Opinion On The Price/Value Ratio

Considering the features of these watches, we’d say they are decently priced. One, the Seiko Shogun sells for nearly a grand while the Sumo sells for about half that price.

Considering that there isn’t much of an upgrade from the Seiko Shogun to the Sumo, it might seem like such a wide price gap. However, with a titanium bracelet that’s quite justified. Titanium is quite difficult to mill and its qualities are also really hard-to-get outside titanium. So, yes the price is justified.

Besides all the benefits of the 6R15 though, the build of the watches themselves, their prices are very much worth it.

You don’t even have to take our word for it. Just listen to what the customers are saying about these two watches to know what exactly others who have bought and used these watches have to say.

Seiko Shogun Vs Sumo – Which Watch For What Occasion?

Seiko Shogun

Seiko Sumo

So, who’s the Seiko Shogun for? From the looks of this watch, and we believe it’s quite obvious, the Seiko Shogun is quite conservative. It also has this refined feel to it that makes it classically beautiful. It can easily hold its own among the more expensive watches we know like the Rolex Submariner. So, you won’t feel out of place wearing this to work or any other formal gathering.  

Also, if you don’t care for heavy time pieces, you’re going to love the Seiko Shogun. With its titanium bracelet, the Seiko Shogun is not as heavy as the Sumo. For many, that’s great because it makes the watch more comfortable for the wearer.  

But then again there are those who equate the weight of a watch with its quality. If you’re one of those, of course, this watch might not exactly appeal to you for obvious reasons.  

That said, the Seiko Shogun wears large so it isn’t something that someone with a slender wrist might be comfortable wearing.  

Also, diver or not, everyone can wear the Seiko Shogun.
The Seiko Sumo, on the other hand, is dressier. It lacks the conservative appeal of the Shogun and is showier in its looks. It’s not our recommendation for you if you need something for formal use. You can use this as a dress watch or for those quick evening out. It’s got a sportyish feel to its looks though if you don’t mind it.  

Next up, you should know that the Seiko Sumo is pretty large. This is a watch for people who have pretty large wrists. Those with slimmer wrists might find the watch a little too large.  

Finally, if you think you can’t afford the Seiko Shogun, then the Seiko Sumo is a great option you can easily go for. You won’t be missing much since the two watches use the same automatic movement.  

Its bracelet is lousy and the crystal could be better. But altogether, it’s a great watch by most standards.

Seiko Shogun Vs Sumo – Which Features Do They Have In Common?

Let’s now check out the Seiko Shogun vs Sumo with respect to the features they both have in common. As much as knowing where these watches differ, knowing the features they have in common should also help us better understand these watches as we compare them.

Get the Seiko Shogun here!
Get the Seiko Sumo here!

Seiko Shogun Vs Sumo Common Feature 1: Cases

The first similar feature between these two watches which we will be checking out is their cases. The Seiko Shogun and Sumo both have similar cases in many respects give or take a few differences in dimensions.

The Seiko Sumo is, as its name probably suggests, slightly larger than the Shogun. However, the difference is only slight.

The Sumo’s case is 44.5 millimeters while that of the Shogun is 44 millimeters. Also, the case of the Sumo is 13.5 millimeters thick while the Shogun’s measures at 13.3 millimeters. For lug to lug length, the Sumo clocks in at 52.1 millimeters while that of the Sumo clocks in at 50.75 millimeters.

So, from what we have seen so far, we can conclude that the Seiko Shogun and Sumo pretty much have the same case. In both cases (no pun intended), the cases are stainless steel and the dimensions tell us that these are watches that wear large. People with slender wrists might want to steer clear off these babies.

That said, the cases are quite good looking alternating between a brushed effect and a polished one on its side surfaces.

Unlike the Sumo and other Seiko watches like the Turtle, the Shogun does not have a distinct appearance. Instead, it pretty much looks like any other conventional watch you know. This understated appearance of the Shogun is what makes the watch more flexible and versatile than the Sumo.

The Sumo, on the other hand, has an appearance for which it is named. It looks like a sumo with its tapering sides included to give your wrist a snug hug for better fitting.

Lastly, on the back of the case, also made of stainless steel, we find the famous Seiko tsunami insignia indicative of the water resistance capabilities of both watches.

Seiko Shogun Vs Sumo Common Feature 2: Dials

In the Seiko Shogun vs Sumo comparison, you also find similarities in their dials. They both have pretty similar dials with the slight differences coming in only in the style of their hands.

Let’s try to look into each of these watches specifically in the appearance of their dials.

Seiko Shogun

Seiko Sumo

There’s the Seiko Shogun on the one hand. It comes with a black matte dial which further proves the fact that this is a pretty conservative watch. Some might find it somewhat boring but it might also be a point of attraction for the more conservative watch people.  

Plus, matte is a pretty logical choice for a dial since it makes the watch more legible. If you’re going to be diving under water, then you’re going to need to be able to see the dial clearly under water.  

The white markers on the dial make a nice contrast to the black dial which also adds to the overall looks of the Seiko Shogun.
The Seiko Sumo, on the other hand, is not as conservative as the Shogun. It is quite showy and would probably be considered more interesting by people with a more bubbly personality.  

In this case, the Seiko Sumo comes with a blue matte dial. So the material is the same however, the colors of the dials are different. We already explained the benefits of matte while discussing the Seiko Shogun. So, we won’t be repeating that.  

Anyway, just like the Seiko Shogun, the Seiko Sumo comes with white markers as well. Its contrast with the blue dial makes the watch super attractive as well.

Seiko Shogun Vs Sumo Common Feature 3: Markers And Complications

Still on the Seiko Shogun vs Sumo, we’re now checking out the markers and complications of the watches which are also quite similar.

Seiko Shogun

Seiko Sumo

The markers on the Seiko Shogun representing the hours and minutes are quite typical. These are pretty much the same kind of markers you see on dive watches, especially Seiko dive watches.  

That said, we found the markers quite interesting and impressive. The markers representing the minutes and seconds are quite similar but the real attraction is with the 12 O’ clock marker.  

As is common in Seiko watches, the 12 O’ clock marker comes in a rhomboid shape. And then running down the middle and partitioning the rhombus into two halves is a downward stroke. The 6 O’ clock, 9 O’ clock markers are also rhomboid. However, they have a more tapering end with a pointed tip when compared to the Sumo. The 3 O’ clock position is where the complication is located.  

You find the minute and second markers on an outer ring also colored in white. The minute markers are small square blocks while the second markers are slim white strokes. This outer ring then slides down and connects to the main dial on which the hour markers are found.   As for complications, the Seiko Shogun uses the 6R15 movement. So, it has the day/date complication which is found at the 3 O’ clock position.  

Finally, there are other markings on the Seiko Sumo besides the hour/minute/second markers and the complication. At the 12 O’ clock position is the brand name “Seiko,” and then at the 6 O’ clock position, you find the signatures “Automatic,” and “DIVER’S 200 m.”
The markings on the Seiko Sumo are pretty similar to that on the Seiko Shogun except for slight differences here and there where the Seiko Shogun is more tapering and pointed.  

Just like the Shogun, the Sumo’s 12 O’ clock marker also comes in the shape of a rhombus and features the downward, partitioning stroke as well.  

Also, the markers for the minutes and seconds are found on an outer ring just like the Seiko Shogun. And the markers are also similar as well.  

Alright, we will just go into the complication. It’s also at the 3 O’ clock position. And since the Sumo uses the same movement as the Shogun, the 6R15, it also displays the day and date.  

Other signatures and markings as found on the Shogun are also found on the Seiko Sumo as both watches belong to Seiko’s Prospex line. The Prospex line contains watches built by Seiko to meet professional standards.

Seiko Shogun Vs Sumo Common Feature 4: Unidirectional Rotating Bezels

All standard diver’s watches come with unidirectional bezels which are important for marking time underwater. Usually, it’s common to find Seiko watches with bi-colored bezels. However, in these two cases, these watches come with one solid color.

Usually, diver’s watches come with bezels and as per standard procedure, these bezels are unidirectional. They rotate in only one direction which is counter-clockwise. Unidirectional bezels are important for the safety of the diver as they ensure that whatever mistake is made, you’re safe. Let’s explain.

For instance, say you knock on something or your watch tugs on something and the bezel mistakenly moves. In this situation, the movement of the bezel would gain time rather than lose time so that you spend less time in water rather than more time. This way, you’re safer and less likely to run out of Oxygen from staying too long under water.

As for the aesthetics, the bezels are ribbed with a polished stainless steel. The ribbed surface makes the bezel easier to grab and each turn gives a satisfying click. Seeing as these watches will primarily be used underwater, these few features are big benefits for both the Shogun and the Sumo.

Now, to the markers of the Seiko Shogun vs Sumo. They both feature a large arrow which acts as the main marker. And then there are the second, minute, and hour markers as well.

The minutes and seconds on the bezel are represented by the same markers which are small, white dots. At every fifth minute/second, these dots turn into slim, tick lines also in white. As for the hour markers, there are no hour markers. Instead, at every tenth second/minute, the markers are represented by Arabic numerals. These numerals count from 10 to 50. The 60th minute is represented by the large arrow we talked about earlier.

The Seiko Shogun and Sumo both come with black bezels.

Seiko Shogun Vs Sumo Common Feature 5: Shatter-Proof Hardlex Crystal

The crystal on the Seiko Shogun and Sumo are the same shatter-proof hardlex. The hardlex crystal is not the worst type of crystal you’d ever find on any watch. Nonetheless, Hardlex isn’t the best either. There are few challenges that this crystal presents and we will go into them right away.

First off, some people might be wondering why these more expensive watches should come with the same crystal as that of the lower priced SKX line. However, we found that the upgrades Seiko made to these watches, of the several of them, the crystal was not one of them. Seiko seemed to have spent more time and resources working on the movement instead which you’d agree is a worthy tradeoff.

Now, the major challenge with Hardlex is that it smudges a little too easily. Plus, if push gets to shove, you can actually scratch the surface of the crystal a little. It doesn’t show too much though which is a good thing. Just keep in mind that you’d be cleaning your watch on your shirt quite often enough in one day.

Like Seiko describes the Hardlex crystal, it is actually quite shatter-proof. It will take quite an impact to actually crack through this crystal but it generally does not shatter easily.

Seiko Shogun Vs Sumo Common Feature 6: Crown

Again, the crown of the Seiko Shogun vs Sumo are quite similar. They are large sized with fine teeth on the sides which give you the friction that helps your grip. In essence, they are the same crowns.

As we mentioned, they are quite large. However, they also come with crown guards which help to minimize their size just a little bit.

Now, there’s one small difference you might notice between the Seiko Shogun vs Sumo. Actually, there are two differences you notice.

The first difference is in the positioning of the crowns. The Seiko Sumo has its crown at the 4 O’ clock position. On the other hand, the Seiko Shogun has its crown at the 3 O’ clock position.

The second difference is in the working of the crown. You’ll feel it when you have to work the crown to set the time. The Seiko Shogun feels slightly grittier and not as smooth as the Sumo. The Sumo, on the other hand, has a pretty smooth operation.

However, that aside, both crowns feel solid with a reassuring weight to them.

Seiko Shogun Vs Sumo Common Feature 7: 6R15 Automatic Movement

An automatic movement is always a benefit when talking about watches. And if the SKX watch line could come with an automatic movement, then how much more the more expensive Prospex line? In the case of the Seiko Shogun vs Sumo, the common movement used is the 6R15 automatic movement.

The 6R15 automatic movement is a fantastic movement with an impressive operation. It beats 21,600 beats per hour which means that it beats 6 times in one second. With this number of beats, you can be sure of an accurate movement all the time.

Even though Seiko puts the accuracy at +25/-15 seconds per day, our opinion is that Seiko was trying hard to be modest. This movement is way more accurate than that. The +25/-15 seconds per day should be more like +25/-15 seconds per week. So, according to our evaluation, these are pretty accurate watches.

The next thing we noticed about the 6R15 automatic movement is that it comes with manual winding. Usually, since the movement is automatic, it powers itself by the swinging of the wearer’s arm. But thanks to manual winding, you can crank up your watch manually and get it working immediately.

You’d appreciate that when your watch has been in the drawer for a long time and you have to get out quickly. Since you don’t have to wait for a while for your watch to recharge, you can quickly crank up your watch yourself and get moving immediately.

Another thing about the 6R15 movement is that its power reserve is pretty solid. This watch can stay for about 50 hours in your drawer (that’s more than 2 days) without direly needing a recharge. However, do keep in mind that as the power reduces, the accuracy of the movement also reduces as well.

Alright, as to whether you can regulate your watch or not, the answer is yes. You can either do that yourself. The video below can help you. Or you can choose to do that at your local watch shop. It’s better to do it at a local watch shop so you don’t tamper with the back of the watch and affect the water resistance of the watch.

Finally, this movement is hackable which means that the second hand stops ticking while you set the time. This ensures that when you set the time, it is completely accurate.

Seiko Shogun Vs Sumo Common Feature 8: Water Resistance

As expected with any diver’s watch, of course, both watches are water resistant. And now that we’re here, we should mention that both watches are strict to the ISO standards. This is an important factor as it assures you of the quality of craftsmanship Seiko put into making the Seiko watches.

Seiko Shogun Vs Sumo Common Feature 9: Dive-Ready Watches

Being that these watches follow the ISO standards, they are dive-ready. So, you can have peace of mind knowing that the watch meets the highest safety and quality requirements.

The bezels are unidirectional, hands and markers are luminescent, and the cases are water-resistant.

Seiko Shogun Vs Sumo – Features Unique To Each Watch

Now that we’ve looked at the similar features to the Seiko Shogun vs Sumo, it’s now time to look at the unique features of each watch. We’re pretty sure this section will form the deal making or breaking point for many buyers. So, you might want to pay attention closely in order to make the best decision.

Seiko Shogun Vs Sumo – Features Unique To The Seiko Shogun

Titanium Bracelet

Unlike the Sumo and other Prospex diver’s watches, the Seiko Shogun is made from titanium. Other watches in the same line are made from stainless steel. So, how is titanium any different from stainless steel?

If you remember Sia’s and David Guetta’s song, Titanium, you probably already have an idea. Listening to your science teacher could also help with that.

Titanium is a really strong element and is literally impervious to almost anything. However, what really makes it attractive is the fact that it is lightweight. But then again, the weight of the watch might or might not be a pro depending.

If you’re someone who equates the quality of a watch with its weight, then you’re not going to want to bet on the Shogun. The Shogun barely clocks in at around 105 grams which is pretty light. Like we said, this is a matter of personal preference. If you like your watch feeling substantial when you wear it, you’d be more inclined to the Sumo and less inclined to the Sumo. If not, you’d probably find the Seiko Shogun to feel toy-like.

Additionally, the Seiko Sumo’s titanium bracelet comes with a diashield coating.

If you know anything about titanium, you’d know that there are two peculiar things about titanium.

The first is that titanium is quite difficult to mill. Of course, this affects pricing as the Shogun is pricier than the Sumo. Plus they are also quite resistant to scratching as well which is the reason for the diashield. The coating protects the watch’s bracelet from scratching.

Some users found that the coating of the Seiko Shogun was better on the exterior than on the interior. You’re less likely to get scratches on the exterior than on the interior. This makes a lot of sense economically. It’s also commonsensical as well.

Seiko Shogun Hands

Now, we will be looking at how the hands of the Seiko Shogun are styled and how they differ from the hands of the Seiko Shogun.

First off, in comparing the Seiko Shogun vs Sumo, you find that their hands have a lot of similarities. The hour, minute, and second hands are almost the same. But let’s dwell on the Shogun’s for a minute.

The hour hand is really just an arrow but with a partition down the middle that makes you remember the 12 O’ clock marker. Then we have the minute hand which reminds you of the 6 O’ clock marker. That one comes in a slender rhombus-like shape. Also, the tip is tapering but not pointed.

As for the second hand, it’s thin and needle-like as expected. There are two parts to the hand as well. You have the thicker part in grey and the thinner part which serves as the pointer. In the middle of these two parts then sits a small wedge which demarcates the pointer from the counterpart of the hand.

Of course, like all diver’s watches, the hands are luminescent. Seiko has filed them with LumeBrite which that they glow in the dark and with great intensity.

Seiko Shogun Vs Sumo – Features Unique To The Seiko Sumo

Stainless Steel Bracelet

In the section before this, we found out that the Seiko Shogun comes with a titanium bracelet. This is another point of difference between the Seiko Shogun vs Sumo.

This bracelet is pretty much the same as other stainless steel bracelets of Seiko watches.

There’s the closure in the form of a deployment clasp. On this clasp is the signature Seiko logo inscribed on the flap which adds to the overall beauty of the watch as well.

Just like you have on the titanium bracelet as well, you also get micro adjustments with which you can fit your wristwatch to size. This does not mean though that the watch can be made to fit a slender wrist. Just felt like we had to make that clear there.

Of course, the claps of this bracelet comes with the diver’s extension. However, even though this bracelet seems to cover most parts on the practical end, it still has a few issues. Thankfully, it’s mostly aesthetic.

Now, with the heft of the wrist watch, you should expect more substance along the bracelet. However, this is not so with the Sumo. Instead, the bracelet is only about 20 millimeters in width which makes it feel a little inadequate. Look at it like securing luggage to the roof of your vehicle with a piece of thread. See how that looks? Great. That’s what the Seiko Sumo’s bracelet feels like. You should seriously consider swapping to something more solid.

Seiko Sumo Hands

We’re still on our review of the Seiko Shogun vs Sumo and this time, we’re checking out the hands of the Seiko Sumo. Like we mentioned, they are pretty similar to the Shogun’s. In fact, in our opinion, the main difference we find is in the hour hand of the watch.

Now, let’s analyze. The minute hand also has that slim, long rhombus-like shape with the tapering end. Then there’s the second hand that’s needle-like as well. This hand comes in two parts demarcated by a small circular wedge. The thicker part of the hand comes in grey color while the pointer part comes in a slim, needle-like look.

The hour hand though is where the real difference between the hands of the Seiko Shogun vs Sumo really shows up. Instead of an arrow, the hour hand is actually quite similar to the minute hand. However, in the case of the hour hand, it is wider. Plus, it also has a small curve on the hand, demarcating the marker into a triangular top and a rectangular bottom.

In the light, these hands are colored white just like the markers. However, with LumeBrite, these hands are super luminescent. It’s safe to say that Seiko applied the LumeBrite generously. So, the hands are plenty visible whatever the condition and from a fairly long distance away.

Seiko Shogun Vs Sumo – Unique Cons

Seiko Shogun Vs Sumo – Cons Unique To The Seiko Shogun

  • The Seiko Shogun comes in pretty lightweight which might be a problem for people who like to equate quality with weight.
  • Titanium is really scratch-prone. However, Seiko tried to mitigate that by applying the Diashield coating. Unfortunately, this coating seems a little cheaper on the exterior than on the interior part. So, it seems to scratch a little more easily.
  • It’s a pretty pricey watch especially in comparison to the Seiko Sumo.

Seiko Shogun Vs Sumo – Cons Unique To The Seiko Sumo

  • The stainless steel bracelet of the Seiko Sumo is probably its biggest drawback. It measures at 20 millimeters which seems a little too small to be supporting the entire watch with its well-crafted case.

Seiko Shogun Vs Sumo – Common Pros

Seiko Shogun

Seiko Sumo

This comes with an automatic movement. And not just anyone, it’s the 6R15 automatic movement from Seiko. First off, the fact that it is automatic makes it quite easy to use. Plus, it’s also great that it comes with manual winding, day/date complication, and is also hackable. The Seiko Sumo also comes with the 6R15 movement.
The Seiko Shogun is obviously well made barring a few compromises here and there for a watch so decently priced, at least relatively. The Seiko Sumo is also well built for its price.
The 6R15 is a super accurate movement. Seiko has advertised this watch as having an accuracy of about +25/-15 seconds per day. However, from use, users have discovered this to be modest on Seiko’s part. This watch is actually quite accurate and in fact, you’re likely to experience that much variance only over a week and not in one day. Same goes for the Seiko Sumo.
Seiko kept to the ISO 6425 standards strictly while making this watch. So, divers can go diving with this knowing that they are using a standard device. Also applies to the Seiko Sumo.
The hands of the watch are very luminescent which is great as it increases visibility underwater. Hands and markers are also very luminescent.
This watch boasts a 50 hour power reserve. This means that you won’t need a recharge in two days after your last use. So you can leave it in your drawer that long. Just keep in mind though that as the watch loses its charge more and more, it also loses accuracy correspondingly. Also comes with a 50 hour battery power reserve.
The watch is hackable which means that you can set all the hands on the watch including the second hand. This works to ensure that the watch is accurate to the minutest detail. The second hand of the Seiko Sumo is also hackable.

Seiko Shogun Vs Sumo – Common Cons

Seiko Sumo

Seiko Turtle

The hardlex crystal is somewhat mediocre. For one, it smudges easily. Two, though it is scratch-resistant, it could probably crack if you try hard enough. Also applies to the Seiko Turtle
Wearers who do not like to wear large wrist watches might find this watch a little too large for them. Same applies for the Sumo and perhaps even more.
The Seiko Shogun has the rubber strap option which some people might have preferred for the purpose of diving. Also does not have the rubber strap option.

Seiko Shogun Vs Sumo – General Feeling Among Users

Now hear how the Seiko Shogun vs Sumo case is faring in the people’s court.

Seiko Shogun

Seiko Sumo

Now, the first thing people seem to love about the Seiko shogun is the fact that it comes with a titanium bracelet. The fact that the bracelet made the watch a bit lighter to wear seemed to be one attribute many people loved about the Seiko Shogun. Of course there were those that would have preferred a bit more heft but generally the weight was okay by many users.  

The bracelet itself also got a great commendation from many users. Even though titanium is scratch-prone, users observed that the Diashield indeed worked wonders. The coating kept the bracelet honest for as long as possible. Plus the bracelet seems to be pretty quiet too from what customers as saying.  

As for value, it’s a generally accepted consensus that the Shogun gives good value for money. Although about a couple of hundred dollars away from one grand, there were almost zero complaints of overpricing. We guess the movement of the watch and titanium bracelet sold it for most people.  

That said, we go to the mineral crystal. Seiko did get a pretty decent level of bashing for the crystal of the Seiko Shogun. There were quite a number of complaints about the quality of the crystal with some deciding to change out the mineral crystal for sapphire which they feel is more befitting for a watch in this class. And who can blame them? We did see instances where customers complained of the pretty serious scratches on their crystal after a short time of purpose.  

But in all though, we guess most people found this wristwatch to be excellent diver’s watches. And it’s easy to see how with the way Seiko kept strictly to the ISO standards.   PS: This time around, Seiko got their chapter ring perfectly.
The Seiko Sumo got a good number of nods of approval from its users. Here’s what we were able to deduce from all of that.  

First off, the quality of the watch appealed to its users. Obviously Seiko did a killer job on the case especially and customers noticed. Plus, the watch passes the ISO standards test in flying colors too which, again, is great news.  

As is common, and is also probably expected, the Seiko Sumo found itself in a competition with the SKX watches in the people’s court. While some felt the SKX07 watches gave better value, others favored the Seiko Sumo giving it accolades as a worthy upgrade.  

Alright, to the complaints. First off is the chapter ring misalignment. So many customers happened to receive their watches with a misaligned chapter ring. Rather than the ring sitting dead center, it came off slightly off. Thankfully, Seiko got that corrected on the Shogun.  

The bracelet too was another pain point for users. Trust us when we say there were many replacements. Just like we already mentioned before, comparing the case to the bracelet, the bracelet just didn’t match up. It seemed pretty inadequate and the 20 millimeter thing too didn’t work for many people.  

But even at that though, the 5 star reviews still continued flying in. Apparently, these few cons weren’t enough to sway people from thinking this watch was awesome.

Seiko Shogun Vs Sumo – In Conclusion

We have looked at the Seiko Shogun vs sumo and we’re pretty sure you’ve drawn your own conclusions. But just before you go, here’s what we think about the Seiko Shogun vs Sumo.

We love both watches but they have they each have their individual strengths and weaknesses from what we’ve been able to deduce. So, here’s what we’d say.

If you’re the more conservative watch person and you don’t care for all the fanciful stuff, then the Seiko Shogun should be your go to. It comes with an understated, classic elegance that would appeal to such class of people.

Now, even though both watches do not have rubber strap options, we’d pick the titanium bracelet of the Seiko Shogun over the Seiko Sumo’s. It’s lighter, of better quality, and more substantial in relation to the watch itself.

But then again if you equate weight with quality, you’re going to want to lean towards the Sumo. But then again the Sumo’s bracelet feels a little teeny compared to the build of the case.

However, the Seiko is the more affordable option and as long as you can bear with the chapter ring misalignment and lousy bracelet. Plus, it’s also less formal and more dressy in its appearance. So, if you’re less on the conservative side, you’d love this watch.

Altogether though, the Seiko Sumo is a great deal if that’s all you can afford. You sure won’t be missing much on the Seiko Sumo.

As usual, it really depends on you. However, if we were absolutely supposed to make just one choice, it would definitely be the Seiko Shogun. The quality of Seiko Shogun beats the Sumo.
