The Seiko Monster might be one of the most polarizing dive watches ever released.

The love-it or hate-it design has camps firmly entrenched on either side, with dedicated followers declaring their love for the quality and value, while detractors scratch their heads at the aggressive and somewhat ugly overall design.

Both sides have a point – the Seiko Monster is no beauty queen. But with a watch like the Monster, that was never the intent. Just look at the name: “Monster”, it was always destined to scare some people.

The Monster is all about rugged dive capability offered at an exceptional value. Like the Seiko SKX, you can most Monsters for less than $500 – and for that you’re getting a pretty amazing watch: 200 meters of water resistance, a reliable low-maintenance mechanical movement, and an incredibly overbuilt dive watch that can withstand a lot of abuse.

Not to mention, the aggressive design has been known to grow on the unbelievers. I’ve witnessed many a convert spend years hating the Monster before finally giving up and falling in love with what it is: an unabashed tool-watch.

Enjoying 10 years of continuous production, there is no denying that the Monster might be one of Seiko’s most popular modern dive watches. The basic model has evolved over three generations, and Seiko has released dozens of highly collectible special editions and unique colors to satisfy collector’s insatiable appetite for this affordable diver.

Let’s dig in, starting with the various Seiko movements used in this model.

Seiko Monster Movements

Reference Jewels Rate Power Hacking Handwinding Day Date
7S26 21 21,600 bph 40 hours
7S36 23 21,600 bph 40 hours
4R36 24 21,600 bph 41 hours
6R15 23 21,600 bph 50 hours

Seiko Monsters primarily use one of four popular Seiko Movements, the 7S26, the 7S36, the 4R36, and the 6R15. All of these movements are all fairly similar, considering that they share the same basic architecture.

The 7SXX line of movements are Seiko’s popular workhorse movement used in much of their entry-level automatic watches since 1996. The 7S26 and 7S36 are identical movements excluding the addition of two additional jewels on the 7S36, which are purely decorative.

The 4R36 and 6R15 are upgrades on this basic architecture, adding hacking and hand-winding capabilities. The 6R15 is the most desirable movement of this group, owing a 50-hour power reserve to it’s upgraded Spron 510 mainspring (a highly elastic alloy developed by Seiko).

None of these movement are known for their fit and finish, however they are incredibly reliable and easy to maintain, due to their relative simplicity and availability of spare parts. Accuracy is typically +/- 25 sec / day, although they can be made more accurate with proper regulation.

Classic Seiko Monsters

First released in basic black and orange, the original Monster set the standard for many of this watches now iconic characteristics: the chunky case, insane glowing lume, a toothy steel ratcheted bezel, and the stubby and short broad-arrow hour hand.

There were many special editions of this watch produced, with some of them being incredibly rare and collectible. See the ‘Limited Edition’ section for more details.

Limited Edition Seiko Monsters

Most of the limited edition Monsters from this generation were released in very limited quantities in Thailand. Although a couple of limited editions have unique specs, the majority are basic variations on the color and materials of the base model (1st and 2nd gen) Monsters.

Why Thailand? Most likely because Seiko has a manufacturing and design facility there and early iterations of this watch enjoyed robust sales in the Asian markets. Or maybe Thai people just like crazy looking watches.

2nd Generation Seiko Monsters

In what may have been a move to take the Monster “theme” a bit too far, the second generation dial was updated to look like the gaping maw of a lamprey attached to a poor lake trout.

Still, the new model proved immensely popular and the upgrades at movement provided the watch with much needed hacking and hand-winding capabilities.

3rd Generation Seiko Monsters

From a strict design perspective, the third iteration of the Seiko Monster is by far the most balanced. Gone are the shark-tooth indices of the second generation, replaced with the trapezoidal markers reminiscent of the first release. The day feature was dropped, and a Rolex-esque magnification window was added to the crystal. The 3rd-gen Monster also contains the premium 6R15 movement, a module otherwise used in the mid-range SARB line (eg. The “Alpinist”, and the “Cocktail Time”).

Unfortunately the 3rd generation models are not as easy to acquire in the U.S. market yet, you’ll have to buy from a global/Japanese marketplace like Ebay, Rakuten or ShoppinginJapan.

Additionally, these models have moved into the midrange market in terms of price (~$500) and no longer have the value that made the original models so attractive to entry level buyers. Still, they are higher quality than the originals and well worth the price.

Seiko Night Monsters

The Night Monsters are blacked-out variations of the original Monster design produced for the Japanese domestic market (JDM), featuring blacked-out PVD bezels, cases and bracelets. Originally intended to be limited editions, these watches enjoyed an extended production run and are relatively easy to acquire online.

Seiko Land Monsters

The Land Monsters are like a strange love-child between a Seiko Alpinist and the original Monster. Although it mostly looks like a standard Monster, it also features a rotating directional bezel controlled by the crown at 2 o’clock. Even though it’s focused on trekking on land, it maintains it’s 200M WR and timing bezel, making it a usable dive watch as well.

Seiko Baby Monsters

The so-called “Baby Monsters” (designated with SNZF) share the iconic styling of the original Monsters but lack some of the real dive-watch capabilities of their more serious siblings. The dial sports the “Seiko 5 Sports” logo, and the lack of screw-down crown downgrades the depth rating to only 100 meters.

These were intended more for the fashion market, and can be had for closer to $100. They still contain automatic movements though, and in that regard they still represent a great value for a mechanical watch.

Seiko Trek Monsters

Another JDM-only version of the Monster released in 2009, the Seiko “Trek Monster” is the land-lover’s companion to this iconic dive-watch. Powered by the 6R15 like the 3rd generation Monsters, the Trek Monsters feature a navigational bezel in place of the standard diving bezel and more of a field watch styling for the dial and hands.

These models are slightly smaller at 40mm, but still boast a 200M water resistance just in case you can’t keep out of the water.

Although some people dispute the fact that these models should be classified with other “Monsters”, I believe they share enough of the design DNA and components to include them in this reference guide.

    Thanks for this guide. I have a couple and am looking for more as I can find them at good prices. The gen 2 “Dracula” is my next target and then the one of the yen 3s. The numbers of variations is crazy! Do you think that the so called baby tunas which seem to be monsters with shrouds should be considered variations? I found your post at watchuseek btw. I think that I might be developing a monster problem. Anyhow thanks.

    Mike Johnson

    Steve, definitely sounds like you are developing a problem – best to seek help! 😉

    I did consider the “Baby Tunas” for the guide, but honestly they are such a weird hybrid between the Tunas and the Monsters they are difficult to classify. For me, the shrouded case makes it more Tuna than Monster, but I’m sure you could argue it either way.

  3. Kristoffer Thomsen

    Hi Mike,

    Thanks for this very clear and informative overlook of the magnificent monsters! 🙂
    Just wanna offer a tiny correction: I don’t think the Blue Monster reads “Limited Edition” on the dial? (on mine it does not, anyways, and the pictures I’ve seen of other Blue monster LE didnt either…
    Cheers! 🙂

I been looking to purchase my first Monster in the UK and could not find all the information I needed to make my final decision until I came across your article.

    Can’t believe they put the ugly rolex style old person magnifying glass in the 3rd generation. It’s horrible and distorts the view.

    Might have to get another 2nd gen version before they become too hard to find. I love my red/black Seiko Monster

  7. WatchNoob

    I saw a unique gen 1 monster in a watch dealer last time,but i dont know the name.Here is the descriptions:

    Gold crown.
    The bezel is blue with North,S,W,E markings.
    I think it has 100m water resistance.
    Dial looks like the super blue .monster but with a (+)(u know what i mean…)design.
    It says ‘limited edition’ on the dial.

    I hope you can tell me which model is that.(sorry for my bad English).If im not mistaken,the strap comes with it looks like it is made from jeans.

    Hey Mike,
    Just came across your post. It seems you forgot to mention the Daddy of them all, the Quartz Monster that predates the Monster lineage by a year. First time the “Monster” hands show up on a Seiko watch. Only produced from 1999-2000. Comes in both black [SLR001] and cream dial [SLR003]. Both extremely hard to find and with the plastic shroud still intact. I am fortunate to still have a NOS piece. Either way, great article.

  11. mike

    Hey! I can confirm SZSC003 is on the market, called \’Blue Eye Monster\” . Seems to be limited edition 1000pc – take this with a grain of salt as it is not from official source, all the Japanese sellers are stating it .


  12. Dave F

    @mike – I am also looking for solid production amount information on these Blue Eye Monsters (SZSC003) as well. I picked one up from a Japanese seller on eBay a few days ago, and it was just shipped – very excited to receive. Only Japanese sellers and Amazon seem to have them. Nothing on the Seiko sites about it. Why such a secret with these? And since blue is such a popular color, I’m very surprised that it’s not being produced in the same quantities as the Gen 3 orange and black Monsters…?

  13. paul

    hi guys i have a first generation orange monster 7s26 made in japan version and it has a outer yellow ring on the dial is this rare ?

  14. Jay Javier

    Hi Mike,

    Saw one online – the SRP315K2 (Uni-directional rotating BLACK ion-plated bezel. Black orange dial with luminous hands and index hour markers. Minute markers around the outer rim.)

    I know the Classic Orange Monster has a SS bezel, but is this one just a variant? Worth getting??


    1. Post
      Mike Johnson

      It’s basically the same, beside the color scheme. I’m pretty sure the “ion-plating” is just another term for PVD, so it’s likely a black coated stainless steel bezel (and crown). If you like the color scheme better, I say go for it 🙂

  15. Monster collector

    The srp315 are $150 these days on clearance. Once sold out the dealers restock. What’s the point? Surely they can’t be making money on these. When will they run out? Seems like an endless supply the last 2 years and yet the srp307 and 309 are scarce as hell

  16. NegNoodles

    I”m seriously in love with this. Hope you’ll consider making other “collections”. For example, the Seiko Tuna or the Seiko Turtle 😀

    My orange monster, was bought about 6 years ago and hardly worn. I am considering selling but I can’t tell what generation it is or where made. Could you possibly let me know some information on it?
    Here are some numbers/letters on the back:

    7S26-0350 AD

    On the front at six o’clock position, in tiny letters it reads: 7S26 (on left side of six marker); and 2084 R 2, on right side of six marker.
    Many thanks

      Mike Johnson

      Sounds like you have a first generation Orange Monster (SKX781) — they were the only generation that used the 7S26 movement. As far as where it was made, you’d have to see if it is a SKX781 or SKX781K — the K models were generally made outside of Japan (Malaysia, Singapore, or Thailand…).

    I am looking at picking up a used first generation orange monster (no papers or boxes) for around usd 100. Normal bracelet scratches but crystal has scratch. Should I buy and 2) can I replace crystal and maintain water resistance?

    Also I have black gen 1 monster I will pick up used for about usd200. Still a good buy (good condition but no papers and box).

    Is it me or are the prices on eBay for these gen 1s going up?????


  21. Anesti Vega

    Thank you so much for creating this guide, Mike! I’ve been wanting to add the Orange Monster to my collection for some time now, but was unfamiliar with the different generations and models. It’s even helped me stay away from some counterfeits offered on Amazon, just by comparing dials and bezels alone.

      Mike Johnson

      No problem Anesti, glad you found it useful! I think the original orange monster is my favorite of the bunch.

  22. Raul

    After stumbling across this site I did some unpacking and found my classic black (SKX779) and Orange Land (SNM037) Monster. In the short time since I have added a Super Blue Monster (SRP455) and a Black Land Monster (SNM035). I now rotate wearing them everyday. I am still looking to add to my collection. Thanks for the info.

  23. Alex

    I heard from a very reliable source that there would be a Zimbe Limited Edition Monster somewhere early to mid-2018. This would be the last ever Monster watch to be produced, so it would be a collector’s dream to get hold on one….

    1. Post
      Mike Johnson

      Hi Gani, typically the second number in the serial is the case number, with the first being the movement. So your watch uses the 0550 case and has a 7s26 movement. It’s a bit strange though, because I don’t think the monster uses the 0550 case (I’ve seen it on Seiko 5’s…)

  24. John

    Great article. I can’t seem a new Monster for sale anywhere, even a 3rd generation version. Have they all been officially discontinued?

    This was a fun read. I have a very early Black monster on steel bracelet manufactured in May 2000. Early on, they came from the factory with a domed crystal, My example also has Arabic/English day/date. Still runs like a champ.

    3rd Generation was when it got included in Seiko’s Prospex Line in the Japanese Market. It was presented as an overseas /reverse import premium model complete with nice box and back history documentation. Back then Prospex was a JDM line not available elsewhere unlike today.

    Hi. Mine SKX781 1st gen Monster has Roman/English days. Does anybody know for what market were R/E days produced?

    You have made a mistake on the seiko SNM037, the 2 o’clock crown controls the movement and the 4 o’clock crown controls the compass dial.

    I am ISO a couple links for a SNM035 Landmonster bracelet.
    Can anyone assist me in locating a couple links?
    Thank you,

    Io lo trovo bello! Solo che preferisco i Seiko Mini Turtle, i Turtle, Samurai, Sumo e Baby Marinemaster e sicuramente un giorno prenderò anche il Seiko Monster
