It’s easy to see why Seiko has such a huge following in the watch industry. With its different watch lines, Seiko has proved to the watch community that it is a brand to reckon with. Today, our review of the Seiko Turtle vs SKX compares two of Seiko’s most popular lines – the Prospex and the SKX line.
So, if you know Seiko (if you don’t, that’s okay too), you’d know that these lines are quite different from each other. Although, generally, Seiko watches are quite affordable, the SKX line is particularly known to be value-priced, costing significantly less than the Prospex line.
As expected, therefore, the Seiko Turtle brings more sophistication to the table than the Seiko SKX. Nonetheless, we have to give it to Seiko as, though the Seiko SKX line is less sophisticated, quality is not in the question.
These are two good quality watches anyone would enjoy using.
So, because this review is going to be a pretty lengthy one and not everybody has the time, we have prepared a comparison overview section. The comparison overview gives you an executive summary of the review to help you make a quick but informed decision.
Of course, there’s only so much information we can cram into an executive summary which is why we recommend that you read the entire review before sinking your hard-earned money into the purchase of any watch.
That said, let’s get this show on the road. You know what they say, time waits for no one.
Seiko Turtle Vs SKX – Comparison Overview
Generally, Seiko watches are great watches and the SKX and Turtle are no different. You can depend on the quality and durability of these watches. Plus, importantly, as divers’ watches, they meet ISO 6425 standards – another reason you can count on them.
In looks, both watch lines are good, although many might tend towards for the SKX for its size. The SKX (the SKX013 in particular) is much smaller and flatter than the Seiko Turtle. The Turtle, on the other hand, only comes in one size which is considerably large.
As for the movement, of course, the Turtle has a more sophisticated movement – Seiko’s 4R36. That of the SKX, on the other hand, is the 7s26 – an automatic movement which leaves us mind-blown considering the price. There’s a small catch though, expectedly.
The 7s26 does not hack, neither does it come with hand-winding. But then again, like the fancier 4R36, it comes with 41 hours of power reserve as well as a day/date complication.
When it comes to offerings, the Seiko Turtle has way more watches in its lineup than the SKX line which has just three watches in its lineup. So, naturally, the Turtle gives you more options just not in size. They all come in one size.
Finally, when it comes to the bracelet, both watch lines have two options you can select from – stainless steel and silicone rubber. And if you don’t like any of those, you can also change out the bracelets for leather or nato.
Seiko Turtle Vs SKX – Our Opinion On The Price/Value Ratio
First off, these are affordable wristwatches on every count. And at their budget price, these watches still hold their own easily in the market. In fact, they over-deliver.
They are durable, pretty accurate, and meet all the ISO 6425 standards.
Now, let’s zero in on the SKX a little more.
The Seiko SKX is the more affordable line, and, expectedly, it comes with its compromises here and there. But, even at that, it’s still a wonderfully sturdy watch.
In essence, if you can’t afford the Seiko Turtle right now, the SKX is not a deep plunge. It’s missing the hacking and the hand-winding which we agree is a big deal. But generally, it’s a great watch.
Seiko Turtle Vs SKX – Comparison Of Major Specs And Features
|Movement||Seiko 4R36||Seiko 7s26|
|Case Diameter||45 millimeters||38 millimeters to 46 millimeters|
|Case Thickness||13.4 millimeters||13 millimeters|
|Strap Thickness||22 millimeters||24 – 26 millimeters|

Seiko Turtle Vs SKX – What Situation Is Each Watch Best For?
| First off, the Prospex line which the Seiko Turtle belongs to is Seiko’s range of professional watches. This is the reason it sells for a price that is significantly higher than that of the SKX watches. |
The Seiko Turtle would make a fine choice for wearers with large wrists. Think about 7 inches. The watch is quite the bold one.
You already know this is a diver’s watch. It might not meet everyone’s tastes, but we can assure you that this watch is solid for your diving needs.
It comes with a range of strap options which includes silicone rubber that’s great for underwater use.
Now, if you’re looking for precision, of these two watches, you might have to go with the Seiko Turtle. Not only is its 4R36 movement more accurate, but it also comes with hand-winding and hacking which the 7s26 lacks.
For casual everyday wear, the Seiko Turtle also works. However, we are not sure we can recommend this as a dress watch because it looks a bit “sportyish.”
But hey, to each man his own, right?
| The Seiko SKX line comprises workhorses that are not afraid to get wet. |
Compared to the Seiko Turtle, the Seiko SKX can suit a wide range of wearers.
The SKX line contains watches with case diameters of between 38 millimeters and 36 millimeters. So, there’s a watch for all hand sizes here. From the slim to the large.
Besides that, the Seiko SKX is a less expensive line compared to the Seiko Turtle. It’s a great entry-level choice for those just getting into diving.
Just like the Seiko Turtle, the Seiko SKX also makes a great casual wristwatch. It might also work as a low-budget dress wristwatch (emphasis on “low-budget”).

Seiko Turtle Vs Seiko SKX – Common Features
Seiko Turtle Vs Seiko SKX – Common Feature 1: Stainless Steel Cases
If you’re familiar with sporty watches, then you probably know that they tend to come pretty beefy. So, if you’re not into beefy watches, neither of these might work for you. If, however, you need this for diving purposes, then best believe that the beefiness of these watches are in your best interests.
The smallest watch you can find between the Turtle and the SKX comes from the SKX line – the SKX013 which measures at 38 millimeters. This is followed by the SKX007 which measures at 42 millimeters.
The largest, on the other hand, also comes from the SKX – the SKX009 which comes in 46 millimeters. This is a pretty large watch which automatically makes it a picky watch. You’d need, at least, 7 inches on your wrist to be able to wear this comfortably.
Now, to the material of these cases. As usual, Seiko uses steel, brushed on the top surface and polished at the sides. The combination of these makes these watches quite attractive, especially when you take into the account the exterior of the bezel and how it fits the case snugly.
At the back of the casing is, well… the back of the case. Lol. It is also made of stainless steel for obvious reasons and is closed by the use of screws, also for obvious reasons. We don’t water getting into the watch while underwater, right?
Also on the back of the case is the characteristic “Seiko Tsunami” insignia – a symbol of the water-resistance quality of the watches.
Seiko Turtle Vs Seiko SKX – Common Feature 2: Dials
The dials of the Seiko Turtle and Seiko SKX are quite similar but differ in a few areas.
For instance, the dials on SKX and Turtle watches both have similarly styled hands.
We have the hour hand which comes in a rectangular shape, with a triangular end and a needle-like tip. As for the minute hand, this one also looks like the hour hand except that the end does not look as triangular. It also has a needle point as well.
As usual, the second hands on these watches are super slim. But what we really like is that the parts before and after the place where the hand is fixed are differently colored. This makes it easier to really see the direction the hand is actually going in.
The markings are also similar. Just like you have on all Seiko watches, all markers besides 12, 3, 6, and 9 are circular dots. The “3” marker is replaced by a day/date complication.
The seconds/minutes markers are little dashes which run round an outer ring just above the dial with the dash thickening every 5th second/minute.
Hands and markers are well luminesced for ease of recognition underwater. Besides that, luminescence is also a really important criterion for meeting the ISO 6425 standards.
| The Seiko Turtle has various models with differently colored dials. |
But before we discuss that, let’s look at other inscriptions on the Seiko Turtle.
Beginning at the 12 o’clock marker. On the Turtle, it’s a downward-facing triangle with sharp angles.
There’s also a needle-like partitioning that runs through the triangle starting from the base, protruding out of the apex.
Underneath the 12 o’clock is the brand name written in capital letters.
The 6 o’clock marker and 3 o’clock marker are similar except that they are slimmer and the partitioning only protrudes from the tip.
Above the 6 o’clock marker, are the following written in descending order “X (for Prospex),” “Automatic,” and “DIVER’S 200m.”
| The markings on the SKX watches differ only slightly from the Seiko Turtle watches. |
At the 12 o’clock position, the marker is similar to that of the Turtle except the angles are not as sharp.
Also, the needle-like tip does not run from the base of the triangle.
As for the 3 o’clock and the 6 o’clock, these come in a cylindrical shape also with needle-like tips.
Under the 12 o’clock marker, you find the following words written in descending order – “SEIKO,” and “AUTOMATIC.”
Above the 6 o’clock marker are the words “DIVER’s 200m.”

Seiko Turtle Vs Seiko SKX – Common Feature 3: Shatter-Proof Hardlex Crystal
For the crystal, Seiko is using its own trademark Hardlex for both of these watch lines. That might be okay for the SKX watches as they are supposed to be value-priced watches. The Seiko Turtle, on the other hand, is more expensive and we’d expect a better crystal.
But then again, to be fair, considering how much you spend getting the Seiko Turtle with the improvements in other quarters, the price is fair. So, the crystal is just one of those trade-offs you’d expect.
So, is the Hardlex really that bad? Well, it isn’t terrible, it’s just that we’ve definitely seen better.
The problems of this crystal is, first, that it gets smudged quite easily. You’re going to have to wipe the face of the watch constantly which isn’t something anyone would enjoy.
Besides that, the Hardlex crystal scratches a little easily as well.
But hey, it would be unfair if we didn’t add that it actually takes quite some work to get the Hardlex crystal to crack. In fact, even if you applied a decent level of force, the crystal could still come out unscathed.
That said, another thing about the glass of these watches is that it is completely flat. They join the bezel at an angle and generally look good without being too overwhelming.
Seiko Turtle Vs Seiko SKX – Common Feature 4: Crown
All watches in the Seiko Turtle and SKX lines have their crowns at the 4 o’ clock position and they are all pretty much the same.
The crowns on these watches are large but they also come with crown guards on both sides which make the crowns look less intimidating. We also like the flow of the crown guards and how they fit with the crowns. It gives the watch a polished look even though it’s a tool watch.
For the sake of a firm grip, the crown comes with fine teeth on the edges. This makes it easier to set the time.
Setting the time requires that you pull the crown full out and then move it intuitively to set the time. As for the date and time, move the crown half out and rotate clockwise for the date and counterclockwise for the day.
Just ensure that you’re not wearing the watch when making the adjustments in order to avoid damaging your watch.
Seiko Turtle Vs Seiko SKX – Common Feature 5: Unidirectional Bezels
Both bezels come made of stainless steel with a ribbed and polished surface which really brings out the beauty of these bezels.
What really grabs your attention when you look at these bezels though is the paint on the bezel. All the bezels have paints that glow in the dark, including the markers as well. This is important because this is a watch with which you’d be diving.
Whether you prefer a bi-colored bezel or a solid-colored bezel, there are different options available for you with either watch and we will get to that in a bit.
Another good characteristic of these watches is that the bezels are unidirectional. This means that they only rotate in one direction which is important for diving.
As you know, underwater, every second counts, and it’s better to end up spending shorter than planned than spending longer than planned. With a unidirectional bezel, whatever happens, even if you mistakenly hit something, you won’t read the time wrong and spend more time underwater.
The bezels of these watches are ribbed to help make the grip firmer which comes in handy when you’re in slippery conditions.
Now, to the markers. The main marker is a large arrow just like you’d find on any bezel with a small circle right inside of it, called the lume dot.
The time markers on the bezel is quite similar to what you have on the dial. The markings are tiny dashes and get thicker every 5th second/minute. The 10th second and minutes get Arabic numerals. This is important because you want your bezel super easy to read underwater.

Seiko Turtle Vs Seiko SKX – Common Feature 6: Bands
The Seiko Turtle and SKX watches both offer two choices when it comes to their bands. There’s the jubilee bracelet made from stainless steel and there’s the rubber option as well.
In thickness, these straps are about the same. However, the Seiko SKX watches are thickest with the least thick strap measuring at 24 millimeters, 2 millimeters thicker than the Seiko Turtle.
Alright, now, we go to the materials used to make the bands of these watches.
The jubilee bracelet (stainless steel) comes with a 5-link design as well as hollow links at the ends. The main links are brushed while the inner links are polished which gives a nice flare.
Now, this bracelet isn’t flashy. So, if you’re into the flashy business, this watch might not be for you. It’s quite understated but it works for some people.
Closure is a deployment with a fold-over, safety clasp. The brand name is also boldly inscribed on the safety flat of the closure.
A more preferable option for diving, though, might be the silicone rubber option. It gives the watch a sportier look but then, that’s what you want to achieve when going diving. Plus, rubber is easier to maintain as it is great underwater and cleans easily too.
The rubber band closes with a regular clasp.
Seiko Turtle Vs Seiko SKX – Common Feature 7: Engine
The engine in these watches has its advantages and drawbacks just like all things in life.
It comes with the unbreakable Diaflex mainspring which holds its own even with excessive winding of the crown.
There’s also the Diashock feature which is what protects the watch from the shock of sudden impact. This way, even if your watch suffers sudden impact, the hands of the clock remain unaffected.
Besides these, there’s also the magic level as well. This magic level is what allows you to wind the watch both clockwise and counterclockwise.
To reduce friction at the constantly moving parts, these Seiko watches come with 21 jewels for each of the 21 contact points in these watches. With this, the durability as well as the accuracy of your watch is preserved.
Seiko Turtle Vs Seiko SKX – Common Feature 8: Automatic Movement
Both of these watches come with an automatic movement. For the SKX watches, this is especially a big deal considering the prices at which they sell. At such an inexpensive price point, an automatic movement is nothing short of kindness.
Now, expectedly, these two movements, although automatic, are somewhat different and we shall be comparing them shortly. You might be surprised, though, that the movement of the SKX line is not so far behind that of the Seiko Turtle.
| The movement in the Seiko Turtle is the 4R36 which isn’t as good as the 6R15 found in the Seiko Sumo – another watch in the Prospex line. |
But just how well does this movement actually perform?
The Seiko 4R36 gives you 21,600 beats per hour. So, in a second, you get 6 beats. It’s easy to see, therefore, that the Seiko 4R36 is a pretty accurate movement.
In terms of power reserve, the Seiko Turtle only has about 41 hours. But the good thing is that the 4R36 supports hand winding.
This means that if power goes out on your watch, you can easily crank your watch up by hand and get it working again.
Now, you want to keep in mind that the accuracy of your watch drops as your watch loses power. So, over time, your watch might need some regulation to be precisely accurate again.
While some say this is easy to fix on your own, except you’re really good at it, we’d advise that you take it to your local watch shop.
It’s easy to mess up with the watch and compromise the ISO-6425-compliant features on the watch.
Another good thing about this movement is that it is hackable. So, whenever you pull out the crown to set the watch, the second hand actually stops ticking.
Again, this is great for time accuracy.
Finally, for complication, the 4R36 comes with the day/date complication.
| The movement on the Seiko SKX is the 7s26. |
Although an automatic movement like the 4R36, this one is, definitely, the runt of the litter among Seiko’s automatic movements.
It’s a workhorse. But hey, at this price point, we didn’t get a quartz movement. That’s actually something to celebrate.
In fact, if we’re being completely honest, the 7s26 movement has a number of similarities which it shares with the 4R36.
For instance, it comes with 41 hours of power reserve and also has a day/date complication.
The main challenges with the 7s26 movement are that the movement isn’t hackable and does not support hand winding.
So, if power is out on the watch, you’d have to wait for it to charge normally (as you swing your wrist). You can’t just crank it if you need it urgently.
It’s a small problem considering how that watch accuracy drops as power reduces on the watch.
Of course, you can always set the time. But since the movement is not hackable, the second hand doesn’t actually stop which could affect the accuracy of the watch.
Watches that are said to be dive-ready or diver’s watches are watches that meet the ISO 6425 standards. There are a number of qualities a watch must possess to be considered a diver’s watch by ISO 6425 standards.
First off, it must be water-resistant down to 100 meters, at least. Both these watches double that, in fact.
Also, it’s important that the back of the casing is screwed down to prevent water from seeping into the watch.
Next, the sides of the watch must be easy to grab on to.
The bezels must read easily, hence, the hands and markings must be luminescent. And not just luminescent, you must be able to read the markings clearly on the watch from a distance as far as 25 centimeters in pitch blackness.
Before we move on, please note that, even though a diver’s watch is said to be water resistant down to 200 meters, it’s better to err on the side of caution. Oftentimes, in reality, the rating on the watch is far less than the actual distance the watch can remain water-resistant underwater.
Seiko Turtle Vs SKX – Features Unique To Each Watch
None of these watches have any unique feature except that the Seiko Turtle has a characteristic turtle shape. They share common features with little differences here and there which we have discussed in the section.

Seiko Turtle Vs SKX – Common Pros
|Although more expensive than the SKX, all things considered, this is still a lineup of pretty affordable watches.|
Plus, the Seiko Turtle has a good number of watches to pick from which is great.

Seiko Turtle Vs SKX – Common Cons
|While the crystal of the Seiko Turtle is great for the price, it smudges easily and we can see how that would be a problem for some.||Same here.|
| The day and date on these watches take forever to change over. Usually, it begins at 11pm and would go on till 4 am. |
It might not be a big deal for some people, but those who prefer a snappy changeover might find it an issue.
Also, this seems to be a general Seiko problem.
|Applies here too.|
Seiko Turtle Vs SKX – General Feeling Among Users
| You can easily tell that customers who got the Seiko Turtle were quite impressed. |
The watch looks good, and though large, seems to feel quite comfortable on the wrist. So, it wasn’t surprising to learn that few people wanted to take this off after putting it on.
Besides that, there were watch enthusiasts who simply loved this watch for the sake of owning it. Apparently, the shape of the watch was it for them, making the Seiko Turtle a collector’s item to them.
Of course, there were a few complaints about size. But, overall, we’d say that complaints about size weren’t so common.
It seemed most customers already knew what to expect when getting the watch. So, for most, it wasn’t an issue.
Now, this one was a common complaint – chapter misalignment.
We’ve come across this complaint commonly among Seiko’s Prospex watches. The Seiko Sumo has the same issue and the Seiko Turtle also has the same.
Needless to say, a few customers weren’t pleased.
Overall though, these watches impressed most people and you could tell from their satisfied comments on different ecommerce platforms.
| The Seiko lineup really did it for many users for a number of reasons. |
For one, many were excited to finally lay their hands on a male wristwatch that wasn’t so large.
The SKX013 with its 38 millimeter case diameter was, indeed, a miracle for many.
As for accuracy, for an inexpensive watch, customers seemed to be quite satisfied with how accurate the watches turned out to be.
These watches have a 3-second accuracy. So, over the course of a long period, they don’t lose too much time, which is great.
For overall looks and aesthetics, well, that was going good until it got to the rubber strap. Not many people seemed to be enjoying the rubber strap that came with this watch.
The major problem seemed to be the toughness, and so, we did see a number of customers swap that out for a Nato.
A few customers did mention about servicing the watch regularly. But you already know that, right?
So, considering all that, we’d say the SKX did fantastic by its buyers, even at such a giveaway price.

Seiko Turtle Vs SKX – Our Verdict
Of these two watch lines – the Seiko Turtle and the Seiko SKX – our pick would be the Seiko Turtle. However, this is only because of the movement in the Seiko Turtle.
Honestly, the Seiko SKX put up a fantastic fight which makes it a great contender especially for the money which the watches are priced at.
However, when it comes down to the workings of this watch, we’d say that the Seiko Turtle makes a better pick. Its movement is hackable and supports hand-winding – two benefits of an automatic watch you always want to have.
