    Pop quiz folks – what resembles a Rolex Submariner watch, says “SEIKO" on the dial, has a screw-in crown and costs a fraction of the price of the watch that it pays homage to?

    No prizes for guessing, it’s none other than the Seiko SKX031K – Seiko’s timeless tribute to the Rolex Submariner. The SKX031K has been around for over a decade (it debuted in 1996 with the introduction of the 7s26 automatic caliber) and sales of this model appears to be still going strong despite its age in the market.

    It took me several months to consider one of this timeless classics from Seiko, albeit its design isn’t entirely original (after all, it is a homage to the Rolex Submariner) and I thought the SKX031K would fill the gap between my 200m, ISO-certified Seiko divers and my dressy Seiko 5 timepieces rather nicely.

    The SKX031K and its Pepsi-bezeled SKX033K are Seiko’s only tribute models to the Rolex Submariner. There are several watch companies that also produce homage Submariner watches. Invicta, AMF, Sandoz and Orient are some of them that have these look-alike models.

    In case you didn’t know, a homage watch is not a replica or fake watch. Basically a homage watch borrows some design influences from the original watch without infringing on copyright and trademarks of the patent holder. To the untrained eye, both the Orient and the Rolex appear similar but there are subtle variations in detail between the two.

    For the rest of this review I will enclose the term "Submariner" (in quotes) to denote a homage Submariner.



    Seiko’s own “Submariner" in detail

    Unlike the other homage watches, Seiko’s SKX031K tries to retain as much design originality as possible while giving the “flavor" of the Rolex Submariner. Probably in an effort to avoid copyright infringements, Seiko decided to use the hour and minute hands from their SKX007/SKX009 diver instead of the famous “"Mercedes-style" hour hand.

    The watch company also altered the dial design of their “Submariners" in a way, perhaps to protect themselves from legal infringements.

    This is to say that Seiko doesn’t have the Mercedes-styled hands in any of their products – in fact they have incorporated such hands in a few Seiko automatic models that don’t resemble the Rolex Submariner.

    To my initial confusion, Seiko offers two versions of the Submariner. I found out that there was also the mid-sized version of this watch – the SKX023K which to the uninitiated, could easily be misconstrued as the full-sized SKX031K.

    In fact, I almost purchased an SKX023K by mistake at one watch store. I didn’t have the photo of the SKX031K Sub in my PDA for reference and had to rely on my memory alone. 🙂

    Fortunately, I recalled the SKX031K sharing the same hour and minute hands as the evergreen SKX007 diver and politely told the store owner that it wasn’t the watch I was looking for.

    I found out that few authorized Seiko watch dealers in Malaysia sell both models simultaneously. Unless you do a proper side-by-side comparison in the same store, you may not notice the not-so-obvious differences between the two.

    Before we continue with the review, let’s first scrutinize the characteristics of the SKX031K and its smaller cousin, the SKX023K.

    SKX031K2 SKX023K

    As you can see from the photos above, both the SKX031K and SKX023K appear to share the same dial layout with the same styling of hour indexes, dial fonts, framed calendar window and bezel markings. The unofficial nickname for the SKX031K is of course, the “Submariner" while its junior cousin is simply referred to as the SKX023K. Going by popular culture, the Seiko “Submariner" is the full sized SKX031K.

    From what I’ve noticed in the watch forums, more Seiko enthusiasts prefer the normal-sized SKX031K to the mid-sized SKX023K.


    In a nutshell, here are the trivial differences between both watches:

    Feature SKX031K SKX023K
    Case diameter 40mm Less than 40mm
    Hour/Minute hands Sharply pointed arrow tips Shorter hands with rounded arrow tips
    Second hand White painted Chromed finish, unpainted
    Minute markers Located on a separate almost vertical, dial ring Printed horizontally on the dial
    Crown and crown guards Large Small
    Lug width 22mm 20mm


    Also as a noteworthy mention is the vast dissimilarity between the SKX031K Submariner and the mid-sized SKX013K, which is actually a boys-sized ISO-certified 200m diver. Yeah, I used to get the model numbers mixed up too. 🙂

    To illustrate the SKX013K diver, here are two photos of the watch. The SKX013K, being an ISO rated diver’s watch, retails for much more than the SKX031K “Submariner". You could say that the SKX013K is a miniature version of the full-sized SKX007K diver.

    SKX013K2 SKX013K

    Top: As you can see, the SKX013K is more like a junior SKX007 diver. This is a true diver’s watch, unlike the SKX031K.



    Model Lineup

    At present there are only two color variations of the Seiko “Submariner" – the black SKX031K and the dark blue dialed SKX033K with the blue/red “Pepsi" bezel. These two models are Seiko’s continual best-sellers, particular in the Asian market, which explains why after a decade they are still produced by Seiko’s overseas factory in China.

    You may be interested to know that Seiko used to have the “Made in Japan" versions of this watch, also known as the SKX031J. The “J" versions (along with the Pepsi SKX033J) appeared in the mid 1990s but for some reason was later discontinued, leaving only the “K" models in production today.

    Top: A rarely seen SKX031J. Note the extra dial text “21 Jewels" and “Made in Japan" on the dial.


    The Seiko SKX031K and 033K both come in a variety of strap options:

    • 22mm folded linked Oyster-style bracelets
    • 22mm folded linked Jubilee-style bracelet
    • 22mm polyurethane rubber strap

    Availability of Seiko “Submariners" on bracelets or rubber straps usually depend on the authorized Seiko dealer’s decision to bring whichever model that they feel is more saleable. From my personal observation, the SKX031K/033Ks on sale in Malaysia usually are fitted with the Oyster-style bracelets. I don’t recall having spotted any that came on the Z-22 rubber strap.



    Look and feel

    The SKX031K is a rather handsome watch albeit Seiko’s efforts not to make it look too close to the Rolex Submariner. It is exudes both classiness and sportiness and is equally at home at formal functions and for casual outings.

    What else can I say? With the SKX031K, you get a taste of the classic Rolex Submariner for a fraction of the price. 🙂

    The dial is easy to read and I like the framed index markers which matches the framed calendar window. The white painted second hand ensures good visibility even in the dimmest environment. The screw-in crown is sort of an unorthodox feature for a 100m-rated, sports watch.

    Did I already mention that the SKX031K is a sports watch? Although some people refer to it as a “diver", it’s actually a diver-like sports watch.

    The SKX031K’s form factor falls somewhere in-between a large diver such as the SKX007K (if you could call the 007K large, that is) and a diminutive Seiko 5 dress watch. It is definitely small when compared to the mammoth looking Titanium or Stainless Steel “Samurai" divers and the SBDC001 Sumo certainly dwarfs it.

    The watch seats well on my wrist and doesn’t flop around. Its modest thickness of only 11mm makes it easy for you to wear it under long sleeved shirt cuffs.

    Top: The framed, chromed index markers of the SKX031K makes it extra special (left). Another angle of my Seiko “Submariner" (right), showing the 22mm folded link bracelet.

    The Seiko “Sub" dial and hands are coated with medium-grade LumiBrite. It’s about as bright as the SKX007K diver and falls short of the fierce luminosity of the SKX779K Monster. Visibility in the dark is quite acceptable – certainly better than the lume used on basic Seiko 5 models.

    What I find a bit odd is that Seiko used "10 Bars" instead of the usual "100m" to denote the watch’s water resistance. Japan Domestic Market (JDM) Seikos typically use Bars instead of meters for their non-diver models. The SKX031K is definitely not a JDM model (although this watch can be found in a few specialty watch stores in Japan) but an international market model. Seiko always uses meters in place of Bars for their non-JDM, non-diver models.

    I’m out of educated guesses and can offer no explanation. Only Seiko Japan’s marketing people may be able to shed some light on this strange practice.

    The bezel is the bi-directional, 60-click type which means that you can only measure elapsed time to the nearest minute. The bezel rotates with positive clicks, not too loose or firm but unfortunately the markers aren’t aligned precisely. I believe this is a common complaint with the Seiko “Sub".

    It would have been better if Seiko had chosen a uni-directional, 120-graduation bezel instead with a luminous dot on the 12 o’clock triangle marker (in the SKX031K, the marker is unfortunately not lumed) – after all, most of their Seiko 5 Sports 200m models (which are not ISO-rated divers) are endowed with 120-click, single direction bezels.

    Above: The solid link, 48A2-JG bracelet clasp (left) vs the 44G4-BE‘s clasp fitted to the SKX031K (right)

    The factory bracelet is unfortunately the folded link (44G4-BE) type with a simple flip-lock safety catch on the clasp, presumably to cut costs. It’s a shame that considering the Orient 2ER00001B comes with solid links. The mitigating factor is that the 44G4-BE bracelet’s clasp has a good number of micro adjustment holes which makes tweaking to your wrist circumference a snap.

    I think it is possible to retrofit the SKX031K’s bracelet with Seiko’s better (48A2-JG) 22mm solid link Oyster bracelet that comes standard with the Seiko SNA225P 7T62 quartz chrono. The end pieces from the 48A2-JG will not fit the SKX031K’s lugs due to different profiling. You’ll have to remove the 48A2-JG’s end piece links and use back the SKX031K’s original end pieces to circumvent this.

    However, the downside of the 48A2-JG’s bracelet is that it only has two micro adjustment holes, which makes perfect sizing rather tricky.

    Above: The SKX031K’s screw-in crown up close (left) compared to the Orient 2ER00001B‘s crown (right)


    The knurled crown is flanked by a pair of softly beveled crown guards. The guards are not as sharp like the original Rolex Submariner or even the Orient 2ER00001B “Submariner". For a 100m rated non-diver’s watch, Seiko thoughtfully included a screw-in, locking crown. I’d say that Orient’s "Submariner" has a better looking crown and guards – closer to the Rolex Submariner’s.

    I like the SKX031K’s crown – it’s easy to grip and not that fiddly to screw it back in, using the popular “reverse-threading" trick.

    The caseback is a rather plain affair, with a highly polished surface with the traditional Seiko “wave" symbol in the center. When I bought the watch, the Seiko protective blue sticker was was glued onto watch and I had a tough time scraping it off. The end result was in lots of minor scratches in the process.

    Fortunately since the caseback is a polished, mirror finish, I managed to remove the marks using Autosol, a well-known German-made metal polishing product. It should however be noted that Autosol is a super abrasive compound and should never used on brushed finish surfaces of a watch, e.g. the clasp of a bracelet, which is usually brushed.



    Above: The Autosol metal polish works wonders on scratches on smooth, mirror finishes. Do NOT use this on brushed finishes!


    It’s worth mentioning that of all the stainless steel backed watches in my collection, the SKX031K sometimes gives me a rash if I wear it for too long without taking it off. I remember reading another SCWF member echoing my sentiments – he experienced the same problem too.

    Seiko’s watches are supposed to be made of 316L Grade stainless steel but I wonder if Seiko used an inferior quality stainless steel with unusually high nickel or chromium content for the 7s26-0040 models. Some people are allergic to nickel or chrome on their skin but I’m not sure which element is responsible for the rash on my wrist.



    SKX031K Custom Mods

    There are not many owners of this watch who mod the SKX031K, compared to 6309-704x and 7s26-0020 divers. I guess like me, most prefer to leave the watch as it is. However, for your personal enjoyment here are some photos of modded SKX031Ks that I’ve collected from the Internet.

    Most of the modifications below are subtle, involving a simple swap of watch hands but a few adventurous owners went for all-out dial replacements. Many off-the-shelf parts from the Seiko 7s-caliber family (such as certain Seiko 5 models) can be used in place of the original components.

    Third party mod suppliers such as Bill Yao, Noah Fuller and Yobokies can also provide aftermarket custom parts for the SKX031K.

        Compliments from non-WIS folk

        I still find it strange that I get the odd compliment on this humble Rolex Sub-lookalike from my acquaintances, although I’d be happier to wear a "better" watch like my SBDC001 Sumo for example.

        Case #1

        Sometime in late 2004, I attended an office luncheon with some of my friends. I was wearing the SKX031K at the time. Ironically, the compliment came from a woman, who was a colleague of my friend. I noticed that she was staring at my SKX031K for about 30 seconds until she finally spoke up.

        What’s that watch that you’re wearing? It looks very nice! Could I see it a bit closer?"

        It took me several seconds to regain my composure and sheepishly showed her the Seiko “Submariner". Perhaps she had mistaken it for that world famous Swiss marque that starts with an “R" and ends with an “x". 🙂

        It’s not what you think it is – it’s actually a cheap Seiko automatic watch, really!", I stammered in embarrassment.

        She looked at it for a little while and said, “Well, that IS a very nice looking watch that you’re wearing. I really thought it was a Rolex!"

        Bingo! Just what I had anticipated what she was thinking. 🙂

        I jested, “Are you thinking of buying one like this for your boyfriend or for yourself? I bet it’ll look good on your wrist too!" Now it was her turn to feel embarrassed so she said nothing more. 😉

        Case #2

        Another real life experience was very recently, when I happened to be wearing my SKX031K "Submariner". A new acquaintance of mine, who is an entertainment industry lawyer by profession regularly goes to the same local Starbucks joint that I do. We’d be there four times a week at night, bringing our laptops along to do our work sitting at separate tables.

        When he had finished his work, he would usually come over to my table and have a chat with me. My friend knows that I’m into watches and he had seen me wear a different watch each time. However, he’s not much of a "watch person" and didn’t seem to be the least interested in my watches.

        It struck me as odd when he saw the Seiko "Submariner" that he appeared to be more interested in what I was wearing. I took it off my wrist and showed it to him – "This is what we call the Seiko Submariner". He expressed surprise, saying that he initially thought it was a Rolex Submariner.

        I took the opportunity to show him the hordes of SKX031K photos I had in my laptop and told him that it was a homage watch. He asked me how much it cost and his eyes widened slightly in amazement when I told him how much I paid for it. Obviously it was much less than he had expected.


        I find this watch interesting as it serves well as a daily beater or the occasional wristwear. Although I don’t wear the SKX031K as often as I do nowadays but it’s a keeper for me. Would I buy this watch again? Yes, unreservedly.

        When I think about it, you don’t actually need a real Rolex Submariner to draw attention towards you when a humble USD115 Seiko also does the same job – and it’s not even a fake watch! 😉

        The fact that the SKX031K is still in production after a decade since its first introduction attests to the popularity and continual demand for this homage Rolex Submariner, especially in Southeast Asian markets. If there’s something I noticed about the Seiko company, if they’ve struck gold with a particular model they’ll continue to produce it as long as there is sufficient, on-going demand.

        I guess the SKX031K will go down in history as one of the "evergreen" Seiko m odels ever produced and I’m glad I own one. 🙂


        Above: This is probably the best looking and flattering photo of a SKX031K I’ve seen so far. (Borrowed picture)


        What I liked:

        • A definitely timeless and classic looking sports watch from Seiko
        • Nicely designed Submariner homage watch without looking too "Rolex-like"
        • High-contrast, easy-to-read white painted second hand
        • Screw-in crown, easier to screw in compared to the SKX007 diver
        • Smooth action bezel with distinctive clicks
        • Looks good in various strap options
        • Suitable to be worn for any occasion, perfect mid-size form factor
        • Affordable!

        What I didn’t care for:

        • Seiko could have used a solid linked bracelet instead of the folded link type
        • Bi-directional bezel with only 60 click graduations
        • Bezel 12 o’clock marker has no lume
        • Caseback steel sometimes gives me rashes on my wrist
        • Watch dimensions could have been slightly larger
        • Crown design and crown guards could have been better designed
        • Bi-directional bezel with no lumed 12 o’lock marker

          Wow, great depth and a model review. I’ve just been looking harder at this watch the last few days. My SKX009 is very well made, and looks great, but it is top-heavy on my wrist (very tippy) and won’t fit under shirt cuffs, which basically makes it a non-work watch. The 031 is more Invicta 8926-sized, and that watch fits fine under cuffs. Like you, I am disappointed that it does not come with a solid bracelet, though on the low end Seiko often skimps on bracelets compared to several other makers. My other disappointment is that internet prices are a bit high, the only option for us Americans. I bought my ISO rated 009 for less than I can get an 031.

          Hello cgrif,

          Thanks for your comments. The 7s26-0020 divers like your SKX009K is obviously a “function-over-form” design therefore sits high on the wrist. It tends to tip over unless you wear the bracelet or strap really snug.

          I wholly agree with you that the SKX031K should’ve been fitted with a solid Oyster bracelet in the first place. Seiko could have easily done it and I guess it was aiming for the low income, mass target group and not watch enthusiasts – so cost cutting was in order.

          You can try to bid from the renowned eBay grey market vendors like Pokemonyu and Premierworld – if you persevere you’ll win the SKX031K at the price that you want. 🙂


          Hi Quartzimodo:
          Thanks for the very informative & interesting review. On a rare business trip,about 2 weeks ago I visited the Mustafa Centre in Singapore with the aim of buying the 031 but unfortunately it was out of stock. The 023 was available but I find it a tad too small and ended up with the 033 (pepsi version of the 031). Then just a couple of days ago I went to the shops in Pertama Complex, KL (TQ, again to your posts)and found that one of the shops had the 023 & 033 but was out of the 031 as well. So, any suggestions where I can get a 031 in KL or PJ ? Contrary to what I read in the internet, prices of these models of Seiko are quite reasonable in Malaysia compared to those in Singapore. That trip south was really quite unnecessary.

          Hi Chan,

          Thank you for your comments. The fact that you missed out buying the SKX031K “Sub” at the Mustafa department store either meant that it was a perpetual best seller or there just wasn’t enough stock to go around.

          You’re likely to find the SKX031K at the older watch stores in KL and PJ. Newer stores usually don’t bother to carry models like the 031K and its counterparts.

          I might suggest that you try to look for it at Syarikat Jam Waktu, located in Sungei Way Subang, off the Federal Highway or any of the watch stores in the PJ New Town/Old Town areas.

          If all else fails, bid on the eBay stores I mentioned in my post above.

          Hope this helps. 🙂


          Thanks, any chance of finding the Orient submariner here ? Just retired my folex sub which I bought in HK about 4 years ago & which had been my daily beater. The accuracy was about 5 secs per day and it could be hacked, all for about HK320.

          Hi Chan,

          Yes, the Orient 2ER00001B may be found at some older watch stores in the Old Town part of PJ that are Orient dealers. You can also check out Sungei Wang Plaza in Kuala Lumpur. The black Orient “Sub” is pretty hard to find compared to its blue dialed counterpart. Maybe the black one is more popular.

          Years ago I was told by a watch dealer that the Orient company was ticked off by the Malaysian Rolex distributor (Woo Hing) for allegedly copyright infringement but it could have been mere hearsay.

          That said, the Orient’s lume is pretty weak compared to the Seiko SKX031K’s lume.

          Happy hunting!



          Is there any way to find out if my Seiko 7S26-0040 is a faked Seiko? Everything looks perfect in my watch but it only last about 14 hrs if I do not wear it and put it on the table. Does not the automatic movement suppossed to last aver 32 hrs when not in use?

          Where can I sent it for inspection or perhaps repair if it is a real Seiko.

          R Tazzi

          Hi Mr Tazzi,

          I cannot tell if your watch is a fake unless you send me pictures of your watch. (Use the “Ask Quartzimodo” contact Form to email me. For anti-spam reasons, I don’t publish my email address in my blog).

          If your Seiko Submariner is a genuine one, I think your main spring is faulty – it may have got tangled up somehow. This may explain why your power reserve is low (I assume that you wear your watch at least 8 hours a day) about 14 hours only.

          Send it to the nearest Seiko repair center in your country OR have it inspected by a professional watch repairman who is familiar with Seiko 7s automatics.

          Good luck!


          Hi Quartzimodo!
          Thanks for great review! I am looking for watches like this. I like also Seiko Monster but this seems too big for me and I feel that SKX031K is good compromise for me. Design of the Monster is excellent and I also like its great lume which can last through whole night.
          Do you have an idea whether lume on SKX031K will last this long too? I am not sure if Seiko used the same grade of Lumibrite for both watches.


          Hi Adam,

          Thank you for your comments. 🙂 Actually the Monster is no longer a large watch by today’s standards as Seiko has started a trend producing oversized diver’s watches. lol.

          The SKX031K’s lume is the same type used on the SKX007K divers, only there’s less of it applied onto the index markers. The lume will last through the night, except that it wouldn’t be as visible as the lume on the Monster (or Sawtooth) models.

          To answer your question, the Monster’s lume is more sensitive and glows brighter.

          Have a great X’mas and Happy Holidays! 🙂


          Hi Quartzimodo,

          thanks a lot for your answer. Is the difference between Monster and SKX031K due to larger area of lume paint on Monster or rather due to thickness of the paint?

          Brightness of the lume is not issue for me. I just want to be able to see whats time even in early morning. So it neednt to be bright but at least legible.

          What you mean by “more sensitive”?


          Hi Adam,

          The Monster has thicker index markers than the Submariner therefore there’s more lume material per square inch. Paint thickness does affect the luminosity too but normally watch manufacturers regulate the thickness of the lume paint.

          The Seiko Submariner is technically not a diver’s watch but a sports watch (unlike the Rolex Sub). The hands and dial markers are legible throughout the night but are not as bright as the Monster’s.

          Seiko has two grades of LumiBrite – the standard white lume which gives of a deep greenish glow and the higher specc’ed one with the off-white, creamy hue.

          The higher grade lume is used on Monsters, Sawtooth, Knight, the SBCB and SBDC-series Prospex divers. This lume is much more sensitive to light, which means you don’t need very strong light to charge the lume, compared to the other type of lume.

          Hope this explains to your satisfaction. 🙂


          Hi Quartzimodo,

          thanks for excellent explanation! I understand now that Seiko puts better lume grade into its diver watches which have more robust build. However “semi-diver” lume should also be OK for me.
          Do you have experience with Citizen’s lume? Is that comparable with Seiko’s? Citizen also have some nice pieces with good movement which I like.



          Hi Adam,

          Citizen uses two types of lume – the older green type (weak and dim) and the new blue superluminova type, on their new Eco Drive models (including divers).

          The blue lume initially isn’t as bright as Seiko’s Monster-type lume, but they fade more gradually than Seiko’s LumiBrite.

          Actually, there’s no hard-and-fast rule as to Seiko’s choice of their better grade LumiBrite. The stainless steel and Ti Samurais are considered “robust divers” but they’re not endowed with the Monster-like lume.

          Yet, some of the latest Seiko 5 Sports 100m watches, which are not true divers come with the brighter lume. Go figure! 😉

          Happy New Year to you, sir!


          Hi Quartzimodo,

          thanks again for your answer. Where did you figured out information about lume paint? I am not able to find anything on this for individual Seiko models.
