Review of Seiko 5 SNK809 – A Lot of a Mechanical Watch for Less than $100

Arguably one of the biggest bangs for the buck with an in-house automatic movement from a storied brand - meet "The Cheapest High-End Watch".

Seiko 5 SNK809

A few years ago, we published a story named “The Cheapest High-End Watch“. We searched for the most affordable high-end watch, comprising a mechanical movement, in-house manufactured of course, from a brand with an undisputed pedigree, preferably family-owned, and the watch should be (relatively) small and elegant. And guess who won the title… not Patek, not Vacheron, not even Rolex or Omega. It was a Seiko 5! While pretty much everyone thinks of Switzerland when we talk about high-end watches, we felt that one specific brand was often missing in the discussion… Today that’s changing already and certainly since Grand Seiko has been positioned as a separate brand, this Japanese giant is being taken very seriously. Japanese movements are gaining traction in general, and despite being cheap (the word affordable doesn’t even work anymore), Seiko 5 watches are true mechanical, bang-for-the-buck “high-end” pieces. Time to demonstrate this, with the not-even-100-dollar Seiko 5 Military SNK809.

There’s a countless number of watches falling into the value proposition category. We have many articles and reviews covering them, from microbrands financing via Kickstarter to established brands offering compelling deals. The Marloe Haskell is a good example of a microbrand piece with a Swiss ETA, coming in well under USD 1,000. The new Timex Marlin Automatics have classic styling, reliable Miyota movements and a price under USD 300 (and it’s the brand’s first automatic line since 1982). Even Hamilton can make a great USD 400 watch with a hand-wound movement. All are great value propositions in their respective price tiers and easy to recommend.

There’s a specific watch, however, that offers an in-house automatic movement, exhibition caseback, day/date complication and clean military aesthetic from a major brand established back in 1881, with still involvement of the founding family – for only USD 100 (and easily found for less). The Seiko 5 SNK809 is part of a broader series of Seiko 5 watches, but this particular model might have the most mainstream appeal with a universally sized 38mm steel case, conservative colour scheme and price that most watch enthusiasts can afford. It does have its flaws, but arguably offers the most complete watch package for the price. All of that falls into our definition of “The Cheapest High-End Watch” – and that isn’t the case for all the aforementioned watches! Period!

Seiko 5 SNK809


Seiko is a watch brand that just about everyone recognizes, whether they never wear a watch or sport a large collection. The company was founded by Kintarō Hattori in 1881 in Tokyo, Japan as a watch and jewellery shop. It wasn’t until 1892 that it started manufacturing clocks under the brand Seikosha, translated as “House of Exquisite Workmanship.” In 1924, production of wristwatches with the Seiko name began and the brand soon became a force to be reckoned with.

Seiko 5 SNK809

The Seiko 5 is one of the brand’s most iconic watch series. Introduced in 1963, it offered incredible value with several innovations. In fact, it had five key innovations that inspired its name.

  1. Day/date complication within a single window, which was uncommon at the time
  2. In-house automatic movement (with Diashock shock protection system comparable to the existing Swiss Incabloc system)
  3. Water-resistance for all models
  4. Seiko’s unbreakable Diaflex mainspring within a durable case
  5. Recessed crown at 4 o’clock

In the 55 years that the Seiko 5 has been in production, a wide variety of movements have been used. What they all have in common, however, is reliability, minimal maintenance and affordability. It’s said that many Seiko 5 automatic movements are assembled with little or no direct human involvement, which removes some of the mechanical romance and mystique but allows for very cost-effective mass production. You won’t find Côtes de Genève, perlage or other embellishments, but the workhorse movements provide an interesting view through an exhibition caseback nonetheless – a decorated movement in a Seiko 5 would look out of place. And here’s a fun fact – former NASA flight director Gene Kranz wore a Seiko 5 model 6119-8460 during multiple Apollo missions (and it still ticks today). If you’re looking for a very high-end piece, the brand offers a limited edition Grand Seiko for over USD 50,000. But in my opinion, a USD 100 Seiko 5 is an equally impressive achievement.

Case And Design

The 37mm stainless steel case of the Pilot-inspired Seiko 5 SNK809 has a matte finish on the front and sides with a polished back. It has a nice military aesthetic and reminds me of a 38mm Hamilton Khaki Field Mechanical (which retails for USD 475). At 11mm in height, it’s not the thinnest watch around, but the thickness helps balance out the smallish diameter on my wrist. The bezel is somewhat heavy (slightly more substantial than the Hamilton), but works well with the case and surrounds a flat Hardlex crystal.

This is an in-house designed crystal that resists scratches better than standard mineral glass but isn’t at the level of sapphire. It’s impressive for the price as I expected to see acrylic. The crown sits at an unusual 4 o’clock position and doesn’t screw down, leaving the case water-resistant to only 30m. That’s fine for rain and splashes, but you should probably avoid swimming. You also can’t wind the watch manually with the crown, which is one of its shortcomings, but simply shaking the watch will wind it all the same. The crown is also a bit small, but not too fiddly when trying to set the time or date.

The caseback has a Hardlex exhibition window that displays the in-house 7S26 automatic movement. The polished caseback and rear lugs contrast well with the rest of the matte finish, and the undecorated movement fits the overall aesthetic perfectly. The case has a nice, substantial weight and no-nonsense attitude, and although simple, has real character.

Dial And Hands

The matte black dial continues the military aesthetic. The outer perimeter has white Arabic numerals marking the minutes, while a smaller interior circle of Arabic numerals mark the hours – this twin-sector display is often found on military pieces, but the outer marks the hours while the inner displays 24-hour military time. The white hour and minute hands are filled with Seiko’s renowned luminous paint (LumiBrite) as well as dots on the outermost perimeter marking every five minutes.

The white lollipop seconds hand has lume in its circular counterweight and also sports a red tip. One of the big perks is a day/date complication at 3 o’clock and you can even choose between English and Spanish for the day (and more languages depending on the market). SEIKO and the 5 logo are shown near the top and add a little depth, while AUTOMATIC and 21 JEWELS are printed at the bottom. Legibility is solid and there’s a lot going on with the dial, but it’s not overly busy and certainly doesn’t come across as generic.

Impressive features continue with the beating heart, which is an in-house Seiko 7S26 automatic calibre. It has 21 jewels, beats at 21,600vph (3Hz) with a 40-hour power reserve. Functions include central hours, minutes, seconds and a day/date complication. Two omissions are the non-hacking seconds and lack of manual winding, but neither are serious flaws in that price segment and are easy to live with. Simply shaking the watch for about 30 seconds will adequately wind it, while daily wear will keep it ticking.

Accuracy is rated at -20/+40 seconds per day, which isn’t exactly a chronometer, but more than reasonable for the price. A simple time adjustment every few days or even once a week will keep your time precise. After a week of testing, the Seiko 5 reviewed averaged only 18 seconds slow per day. At that rate, I’d probably only adjust it once per week.

Viewed from the exhibition caseback, it’s not a refined beauty, but still provides an interesting look at the mechanics of an automatic workhorse. It may not have Geneva stripes or blued screws, but is nevertheless a cool sight and I’m very pleased that Seiko included a Hardlex exhibition window on such an inexpensive piece.


If there’s a standout flaw with this watch, it’s definitely the black 18mm canvas strap. I consider myself something of a strap snob and it’s not uncommon for me to replace manufacturer’s ones with better third-party options. However, the strap that comes with this Seiko 5 is just downright bad. It gets the job done, mind you, and looks decent enough on the wrist, but it’s fairly uncomfortable, snags on the metal loops when trying to strap it on (from the loosely stitched piece covering the holes) and looks and feels cheap while the actual watch does not.

The matte steel buckle and loops are nice enough, but the positivity ends there. I don’t despise it and would probably be fine if stuck with it, but I’ll be switching to a nicer canvas strap. It’s worth the USD 20 upgrade. To be fair, the strap has broken in a bit from daily wear and is more comfortable than on day one, but I’m still eager for a replacement. But then again, at USD 100 or less, you can’t have it all.


The Seiko 5 SNK809 is one of the most impressive watches I’ve taken a close look at this year. It’s not a luxury piece and certainly won’t attract attention, but for just USD 100 (or less on the web), it offers a lot more than a mechanical watch should. A reliable, in-house automatic, all from a well-established brand, with the founding family still involved in the brand, with a steel case and restrained dimensions… And let’s not forget that it’s been in continuous production for 55 years. Certainly not the same mechanical marvel as a Patek, but still, we dare to say it again: this is the most accessible high-end watch in the world (and by quite a margin).

Seiko 5 SNK809

Notwithstanding the low-quality strap, this watch makes even a value proposition like the 38mm Hamilton Khaki Field Mechanical seem expensive. That watch certainly has a Swiss ETA 2801-2 and hacking seconds, but Seiko’s movements aren’t to be blamed (far from that). When you add everything up, the Seiko 5 SNK809 just might be one of the best horological bangs for the buck. It’s a cool watch for seasoned enthusiasts but mainly is a perfect piece for first-time mechanical watch buyers – Christmas is coming…

This particular model may have recently been discontinued by Seiko, although some retailers claim that one can be ordered on request. The Seiko 5 Military SNK809 was produced in the millions, however, and is very readily available. Sites like Amazon and a host of third-party retailers carry it with prices ranging from USD 109 to a mind-boggling USD 65. Seiko also offers a three-year limited warranty on all new SNK809 models.

  1. Nice write-up!

    I have been wearing mid-range mechanicals for years, and recently caught the SNK809 for $69 USD at a certain popular online retailer so I picked up two of them – the other to give to my teenage son (who is all G-Shock). I am impressed. I love the size, legibility, and I’ve never seen a watch that can go with so many different strap colors and materials. Drop the stock band and grab some after market straps – leather, NATO, silicone, etc. Everything looks and feels great on this watch. I’m very impressed.

  2. Great review! And great coincidence because just today i was telling my japanese mother at lunch about how awesome (and japanese) this watch is! Didn’t know it was discontinued, is anything going to replace it?

  3. Yo compré este calibre hace 22 años, aún funciona con una precisión de +4 sg. Día.
    Desde entonces valoro más el movimiento que el nombre de la marca que los comercializa a la hora de adquirirlos.

  4. There is much to be admired about the much-aligned 7S26 movement. I looove the utilitarian finishing that says “We know you know better than to believe that a few machined whirls makes this watch keep better time.” Great review except for one thing.
    How exactly has GS became more respected since dropping one instance of the word “Seiko” from its dials? This is the kind of marketing nonsense which really annoys me. I remember maybe a year ago, Ariel Adams talked about Mido “not having a story”. Viola! Their website changed and now we are being told that the Mutifort was “inspired by Sydney Opera House”, that the Commander is “based on the flutterings of a moth’s wing at sunset” and the Belluna is “designed to represent the elegance of today’s women”. OK, I might have made the last two up. 🙂 But the point is, the only people who believe this drek are those who get paid to do so.

  5. I have owned one of these for some time. The only real problems are . no sapphire crystal (the mineral glass scratches easily), accuracy not great (but good enough for day to day needs), no hacking/hand winding (could be 7S26 movement getting swapped for NH36).
    Gets used a lot though

  6. Some Pateks don’t hack either!
    Of course it is unfeasible to expect sapphire at this price, but a scratch crystal is never pleasant. A good thick Hesalite might make it more desirable for the WIS crowd.

  7. I respect Seiko enormously as a watch manufacturer; they’re very capable of producing pieces in every price segment, each with dignity and representing decent value propositions. However, I do think they have major flaws with design and marketing that are holding back. The surge in popularity of brands that the WIS frowns upon (MVMT, DW, etc) that represent nothing interesting from a horological stand point and offer arguable poor value is all due to appealing designs to younger audiences and curated online marketing content (millennial-friendly social media images, etc.). If by 2030 75% of the global working population is composed by millennials or younger, Seiko will be left behind unless they wake up. The Seiko 5, while a great value starter piece is clumsy, from a design stand point. It’s not versatile enough, can’t be worn as a daily transition between the office and the bar as easily as a MVMT (or any generic “fashion” piece) can. ABTW did a YouTube vlog commenting on Seiko’s marketing department, stating their press releases and online content made it challenging to work with, their marketing department inefficient. I know aesthetics are subjective in nature, but the rising tidal wave of generic pieces hints to there being a generational chord that Seiko is failing to strike (Many of which, when producing mechanical pieces, power them with Japanese movements and then price them x amount of times what Seiko watches goes for).

  8. Hacking seconds are overrated 😉
    None of my watches have it (two of them don’t even have a seconds hand).

  9. Hi
    Additional information about the Seiko 5 SNK809 dial.
    This dial is very inspired (almost a copy) of german Aviator (Flieger) Type B watches from WW2.
    Check out Laco Type B or any other Flieger Type B. This is the design. Production started 1941 of watches with this design. Of course, because of readability and practical reasons the original Flieger Type B watches were bigger, with a diameter of 55 mm.

  10. A watch w/o seconds hacking or manual winding, with a manufacturer acceptable accuracy of +/- 20-40 seconds a day… is not “A lot of mechanical watch” for any kind of money!!! I’m sorry, but that sounds like terrible performance at any price. Even if you get one that does better than that on accuracy, the lack of hacking is a big deal. Isn’t the purpose of a watch to tell time? If it was off +/- 30 seconds per day and you had hacking, you could at least sync your watch up at the start of the day and not be too bad off.
    Also, the watch looks nice in closeup on the internet, but on the wrist, it looks VERY small compared to most modern watches. The person in the 1 wrist shot in this article must have a very small wrist. Overall, I feel this article is quite misleading

  11. Interesting article!
    Had never thought they made watches like these 🙂
    Thinking seriously of getting one but I was wondering, if you buy it today, is it supposed to be “Made in Japan” or is it normal that the ones you find are made in China?

  12. As a reply to Magnus these are made in Malaysia. You can find Japanese assembled models which are made from the same parts. Those are usual 20 to 30% more expensive. If you want to go for a Japanese built Seiko look into higher end models like the SARB or SARY.

  13. “Even if you get one that does better than that on accuracy, the lack of hacking is a big deal. Isn’t the purpose of a watch to tell time?”
    Yes, it is, but not necessarily up to a few seconds’ accuracy, anyway nogt for most people, certainly not for mvintage mechanical watch lovers. Most non-military watches don’t hack at all. If you want real accuracy, buy a $ 10 quartz watch and don’t bother with mechanical movements at all, as you”l only be disappointed.

    “Also, the watch looks nice in closeup on the internet, but on the wrist, it looks VERY small compared to most modern watches”. Well perhaps it does, but not everyone is into most modern watches which have a tendency to grow out of all proportions. I think the Seiko 5 size is just fine, so is the watch (Yes, I own one and it has done me proud for over 12 years now, without any servicing, never been late for an appointment wearing it, despite the hack-lack) and so is the article. And the conclusion is dead on: best price-quality performance you”l be likely to get, ever.

  14. By now the 7s26 is outdated, but these watches are still on the market, so here are my comments, The watch is no doubt a handsome achievement and in today’s market a nice 38mm sports watch is hard to find. The quality of the 7s26c movement, in which the flaws of this series are supposed to have been corrected, is still inconsistent in many respects. Seiko 5’s that had 6009’s with 17 jewels and no jewel or ball bearings carrying the rotor, would start working as soon as you picked them up and you could count on them to continue running once you put them on, even without the initial few shakes. After only half a day of wear, they already built up their 40 hour power reserve. As a matter of fact, the word was that the reason that Seiko did away with the stem-wind apparatus was that the magic finger device was so efficient that there was no need for it. Seiko 5’s were known not to be well adjusted out of the factory, but you could adjust them to about +/- 1 or seconds per day, which was fantastic considering that you could buy them in electronics and camera stores for a discounted $30, in the US during the 1980’s. No such luck with the 7s26 series. I’ve handed 5 already. I have an A model that is already over 20 years old and I am still satisfied with it. Two C’s that I would vary between 5 and 20 seconds per day when adjusted to the optimal. One seems to compensate for its error such that it is days before being a second or two off, but it never stores up more than about 15 hours of power reserve. One got seized up during my attempts at adjusting. Of the other two, I did not try adjusting them as they fall within a tolerable 5 second gain or loss per day, but they do not seem to build that power reserve. My conclusion is that Seiko’s ball bearings, added jewels, and movable parts on the regulator are just bells and whistles. My verdict: They don’t make em like they used to. And as for the keyless works being moved to the back of the movement, this has no advantage to the consumer. Seiko watches were such good workhorses that by the time they needed service, more than 20 years had passed, and by then the case could be expected to be so worn, or simply because of the passage of time, the owner could be expected to be ready for a new watch.

  15. After playing a little with the adjuster on the escapement, my seiko is consistentely running under 3 secs/day average deviation. A bit sensitive to “lifestile” (gains on the shelf whlile i’m sleeping, looses when worn) but it’s an amazing machine for the cost.

  16. I own a Seiko SNK809-K2 and it is the worst watch I have ever owned..
    All the “Mechanical fanboys” think this is the best thing since sliced bread.
    Mine gains 5 SECONDS a day or 2 Minutes and 30 Seconds a Month and this is OK
    My non radio controlled Casio G-Shock gains 2 Seconds a Month … My Casio G-Shock is 75 TIMES MORE ACCURATE.
    Save your money and buy a good quality Quartz watch for the same money.
    The Seiko SNK809 K2 has NOTHING going for it.
    A watch that does not hold accurate time is a bad watch ..Regardless of how it is powered.

  17. @Brian Hall – 5 sec/day is already quite accurate for a mechanical watch, specifically when considering an accessible mechanical Seiko watch – remember that 5 sec/day is equivalent to a 0.005% margin of error (not that large of a deviation, admittedly). Of course, if high accuracy is your thing, then quartz or batteries will surely make you happy. No mechanical watch will ever be as precise, simply because they are mechanical.
