Hi guys. Today I’m writing about the Seiko SNZF17 review, or the so-called Seiko Sea Urchin watch (more on that later on).
It’s also widely known as poor man’s Rolex Submariner – and no, I’m not talking about the Invicta 8926 here.
While the Invicta blatantly copied the Submariner design, this Seiko SNZF17 injects Seiko’s own design characteristics (specifically Seiko 5 Sports design) into the well-loved Submariner.
Above is the Seiko SNZF17 – Sea urchin
And here is the Rolex Submariner
The end result is a watch that looks like the real thing but at a very affordable price (for an automatic watch that is).
And I can’t praise enough how it still has its own identity. For me, that’s the paramount aspect that a watch need to has.
And being affordable (can be had for less than $150 online if you’re willing to wait), it’s perfect as a beater watch and for those just entering into the automatic watch world =P
Why Sea Urchin?
First things first, why the Seiko SNZF17 is dubbed the Seiko Sea Urchin?
Frankly speaking, I’m also not sure why this is so. But from what I can gather, the watch is called as such because of its resemblance (somewhat) to the sea urchin.
Above is a your normal sea urchin. Hmm.. See any resemblance to the Seiko SNZF17?
I mean both are black in color, and the Seiko SNZF17 has that white marker lines that looks just like the spike coming from the sea urchin LOL.
Let me know if you feel this explanation is the best for the nickname. Otherwise, do let me know the real reason in the comments section below =)
Without further ado, let’s go to the Seiko SNZF17 review shall we.

Iconic Rolex Submariner Watch Design
There are many watches out there that has the iconic diver’s watch look of the Submariner. Well, we can’t blame them.
Index markers, unidirectional rotating bezel with minutes on it, black and white color scheme, stainless steel case, lume applied lavishly on the hands and markers – these are the elements that’s perfect for a diver’s watch.
In fact, some of these (such as the rotating bezel and lume) are the requirements for a watch to comply with the ISO diver’s watch specification.
Which is why if you ask me, it’s quite impossible to make a good diver’s watch without making it look similar to the Submariner.
Practically almost every major watch brands have one of these and Seiko is no exception.
But this Seiko SNZF17 is the one watch that closely resembles the Rolex Submariner, albeit with slight changes to incorporate Seiko 5 Sports’ identity in it.
Submariner-Like Dial Design
The most glaring similarities between these two watches are the index markers, bezel and dial signature.
The index markers of the Seiko SNZF17 are a combination of circular and rectangle markers.
Rectangle markers are used at the 6 and 9 o’clock positions while the 12 o’clock is using a trapezoid shape marker.
The bezel of the Seiko SNZF17 is a unidirectional rotating bezel type that’s common with diver’s watches.
For those that are not familiar with it, it means the bezel ring (the one with the 10, 20, 30, 40 and 50 markings) can only be rotated counter-clockwise.
This is so that it can be used to time dive duration easily (read my guide on how to use these HERE).
As you might have noticed, the bezel markings are almost similar to the Rolex in terms of its placement though the font is bigger.
Lastly, the dial signature design on the Seiko SNZF17 somewhat resembles the Subs due to the placement of texts at the bottom of the dial.
I never see any Seiko 5 with this placement design, so I guess Seiko did do it in purpose to mimic the Rolex LOL!
But The Seiko SNZF17 Also Has Its Own Identity
Similarities apart, the Seiko SNZF17 do have its own identity, characteristics taken from Seiko 5 Sports line up.
For instance, we can see that the hands of the watch is bulkier than the Rolex. Its big stature and design of the hour hand reminded me of the Seiko SBDC033 (I started think those are the actually exact same design. Hmm..)
It’s the same with the rectangle markers which are slightly wider than the Subs. In effect, these make the watch look sportier and has more lume applied on it.
Another thing that greatly differentiates the Seiko SNZF17 from the Subs is the presence of day date display at the right side of the watch.
The Rolex doesn’t has the day, instead having a bigger date window with a magnifying glass.
The day date display on the Seiko SNZF17 is better in terms of practicality and usefulness as we don’t have to check our smartphones if we can’t remember what day or date today is (happens to me a lot as I grow older LOL).
Elegant Rolex Submariner, Casual Seiko SNZF17 For Beater Watch
Even though both watches look similar, I found that the Rolex Submariner is a bit more elegant than the Seiko SNZF17.
I think the Swiss watch’s smaller elements (e.g hands, markers, bezel font, etc.) make it more pleasing to the eye, looks simpler and yet very attractive.
It’s the hallmark of great design after decades of innovation from the company. The Seiko SNZF17 on the other hand is sportier (it’s a Seiko 5 Sports watch after all) with the bigger hands, markers and font.
The day date display, though is very useful, seems to disturb the dial. This makes the watch look busy and make it less pleasing.
Which is why I have the opinion that the Seiko SNZF17 is more suited for an everyday beater watch, watch that you can use practically anywhere and anything.
Be it yard work, going fishing, carpentering, all those tough works – these are the situation where you’ll never even think of using that precious Rolex and the Seiko SNZF17 is just the right candidate for that =)
41 mm Stainless Steel CaseSeiko SNZF17 has a 41 mm stainless steel case which I found to be the best size for an average guy’s wrist.
It’s not too big and can easily fit onto any wrist, unless of course, you have very gigantic hands.
The thickness of 13 mm is not definitely not a thin one, but since this is a sports watch, I think this is acceptable.
The lug width or strap width is 22 mm, a bit wider than the 20 mm straps that I prefer for such a watch.
On top of the watch is a hardlex crystal, Seiko’s own version of hardened mineral crystal.
But my experience with this it is it’s not any better in terms of scratch resistance, compared to normal mineral crystal.
Some online websites will list that it’s scratch resistance or scratch proof but this is simply not true. Only sapphire crystal can be said to be scratch resistant.
Even so, it’s not that hard to keep the watches from deep scratches as long as you follow the basic rule of avoiding contact between your watch and any metal or hard surface.
A few rules that I always follow to avoid scratches on my watches are:
- Don’t keep your watch in a pocket that also contains coins or keys or any other metal
- Don’t put your watch face down on the table
- Be wary while walking next to a wall to avoid direct contact between the watch face and the wall surface
I’m sure that if you follow these simple rules, your watch’s pristine crystal will not be suffer from any deep ugly scratches =)
Don’t Like the Black-White Dial? There’s A Pepsi Version Too
Apart from the traditional black and white dial design, Seiko also produces the Seiko SNZF15 which is basically the sea urchin but with a blue dial and and pepsi bezel colors.
It’s a fun little timepiece that’s perfect for casual and outdoor use.
Above is the Seiko SNZF15 – the funky pepsi colored version of the watch.
100 m Water Resistance, No Screw Down Crown
Even though the Rolex Submariner is a diver’s watch, this Seiko SNZF17 sea urchin is not exactly a full fledged diver’s watch.
It has only 100 m water resistance, and without any screw down crown. The latter caused me to think that this is more to a general purpose sports watch instead of diver’s watch.
It’s a bit of a let down but then we need to remember that at this price, it’s quite hard for Seiko to make a real diver’s watch (such as the Seiko SKX007).
The strap of this watch uses a stainless steel bracelet that’s built good and sturdy. I like how it comes with a double lock clasp with Seiko signature printed on it.
The use of double lock clasp gives more assurance as we know the watch won’t fall off accidentally.
But on thing that I don’t really like is the use of hollow end links on the bracelet.
It’s the connecting piece of the bracelet to the watch that is built of thin plates, instead of solid stainless steel.
I found that this hollow end links tend to rattle and create metal touching noises when we are moving out hands around. Well, such drawbacks are to be expected for a watch in this price range.
Robust Seiko Cal. 7S36 Automatic Self-Winding Movement
Inside the Seiko SNZF17 is the legendary Cal. 7S36. It’s one of the brands movement that’s has been proven to be robust and reliable.
The movement has 23 jewels with 21,600 vibrations per hour or 6 beats per second. It’s accuracy is fairly average, at +- 15 seconds per day. The power reserve of this movement is about 41 hours.
Older Generation Movement – Non-Hacking and Non-Manual Winding
Even though the 7S36 movement is a good with proven track record, it’s undeniably an older generation movement from Seiko.
The 7SXX movement series originated from a few decades ago but due to its effectiveness, it’s still around until today.
What I don’t particularly like about it is it’s non-hacking and cannot be manual wind. Non-hacking means the watch seconds hand won’t stop when we pull out the crown to adjust the time.
For some, this is considered unacceptable since they can’t precisely set the time accurately.
The Seiko Cal. 7S36 automatic movement can be seen from the exhibition caseback of the SNZF17
But for me, it’s not a very big deal as a minute or two inaccuracy is acceptable (at least to me LOL).
It is the manual winding feature that I really miss in the movement.
That feature enables us to recharge/tighten the movement’s mainspring, increasing its power reserve just by turning its crown a few times.
This makes it easier for us to keep the watch running especially during those times when you just can’t wear it such as wearing your more expensive watch to a formal event.
Without this feature, we are left with having to wear the watch to keep it alive.
Or the other option is to use watch winder which can actually has the same cost as the watch itself LOL.
Problem To Keep It Accurate?
One of the main complaints about the Seiko SNZF17 is its accuracy. Some of its owners complain that the watch is not a good timekeeping device and has accuracy problem.
Well, in my opinion, automatic watch is already quite well known to not be as accurate as a quartz watch.
But again, this is something that not all people are aware of (especially those starting to learn about watches in general), which is why this complains surfaced.
Even the most accurate automatic watch, the COSC Chronometer watch can has a +4 or -6 seconds per DAY deviation.
Meanwhile, a quartz watch has +-10 seconds per MONTH accuracy.
Granted, automatic watch’s accuracy is its weakest point. But the main thing that make it unique is the centuries old movement that’s full of mechanical goodness.
There’s no electricity used in there – just gears, springs, rotor etc. to keep it running.
And the fluid seconds hand movement as well as the exhibition caseback are the elements that you can’t never get from a normal quartz watch.
But should your Seiko SNZF17 has a problem to keep it’s accuracy, say it’s gaining or losing almost one minute per day, then please bring it to your watchmaker to get it fixed.
Sometimes, the watch can be magnetized which caused it to lose its accuracy. This can happen if you let the watch get too close to a magnetized source, such as speakers, fridge, TV, etc.

Who Is This Seiko SNZF17 For?
Fancy a Rolex Submariner but don’t have the cash or don’t feel like splurging it on a watch?
Then this Seiko SNZF17 sea urchin is definitely for you. It’s not like other watches that imitate closely (ehem, Invicta..) but it has the elements with some styling unique to Seiko 5 Sports, making it a watch on its own.
It’s affordable price makes the watch a good candidate for those wanting to buy his/her first automatic watch.
And since it’s Seiko, you’ll be guaranteed of a good quality timepiece to own.
Who Should Not Get The Sea Urchin?
Anybody looking for a real diver’s watch might want to skip this Seiko SNZF17.
It has a fully functioning unidirectional rotating bezel and lume, but that’s as much as it gets in terms of diver’s watch.
The 100 m water resistance rating is not bad too, but the lack of screw down crown is what makes me feel it’s not a good watch for diving.
For me, I’d be more at peace if I’m wearing a real diver’s watch – such as the Seiko SKX007 or SBDC033, not just because of the screw down crown, but also because these watches complied to ISO requirements for diver’s watch.

Seiko SNZF17 or the sea urchin is a one of the best affordable automatic watches around. It’s a good solid watch with nice design.
And I have to say its affordable price makes it a great choice to be used everyday as a beater watch for any usage.
I mean, even if the watch breaks while you were mountain hiking, it’s just a less than $150 Seiko right?
And not to mention its resemblance to the Rolex Submariner makes it a nice substitute – until you can save enough $$$ to buy that Swiss legend =)
