Seiko Sports 100 7A28 ‘First Analog Quartz Chronograph Movement’ Vintage Watch Hands-On

Seiko Sports 100 7A28 'First Analog Quartz Chronograph Movement' Vintage Watch Hands-On Hands-On

People who know me are aware that I’m not much of a vintage watch guy. Though, in my increasing maturity, I do find myself interested in older watches that interest me. I’ve come to find that I employ a sort of rule when it comes to vintage timepieces that I am keen on. For the most part, I am only interested in older watches that came out during my lifetime, and that of course have aesthetic elements and stories that I value. One such watch is the Seiko Sports 100 7A28, which during its roughly 10 year production run was released in about 40 different versions. Keen on owning one for a long time, my dream (more like a box I needed to check) came true a few months ago with most of the thanks going to good ol’ eBay.

The Seiko 7A28 isn’t a particular watch, but is actually a movement. Though watches with the caliber 7A28 movement had the name of the movement in the name of the watch – even though they had other reference names as well. For example the particular model I got is known as the Seiko 7A28-7060 as well as the Seiko SPR025J1 – and apparently it is incredibly rare (as well as really cool).

Let me first explain the technical appeal of the 7A28. This is important because outside of being featured in many seriously iconic 1980s futuristic watches, the 7A28 movement was sort of a big deal. More so, Seiko doesn’t even produce anything like it anymore. The 7A28 movement was the world’s first quartz analog chronograph movement – brought to you by the same company that first released an analog quartz watch in 1969 with the original Seiko Astron.

While the performance of the 7A28 isn’t exactly breathtaking by today’s standards, it is still a very impressive movement, and its production quality and features are still better than most of today’s far more cheaply produced quartz chronograph watches. We are starting to see it happen more and more, but just you wait because 1970s and 1980s era quartz movement-based watches (the good stuff) are going to be an upcoming craze among watch collectors. It might not happen tomorrow and you aren’t likely to see bored rich guys attempting to impress one another by spending a million dollars on them… but sooner or later these are going to really go up in value.

A good reason that Seiko 7A28 watches (and timepieces like it) are going to go up in my value (in my opinion) is that finding ones in good condition is incredibly tough. Why? Because people wore these watches for years! In fact, good condition Seiko watches from long ago are often hard to find in general because they were too good. What does that mean? It means that people wore them for years, often until they wore out. So you can imagine my delight in finding this otherwise incredibly rare Seiko 7A28-7060 in NOS (new old stock) condition. It even still has the remnants of a blue plastic sticker on the case back. More on the watch in a bit after I finish talking about the movement.

This is a good time to mention an excellent article that details the Japanese 7A28 movement as well as showcases a great number of the 7A28 watches. I find it a bit amusing that the article I just linked to references aBlogtoWatch, and now I am referencing it. Anyhow, Seiko introduced the 7A28 movement in 1983 (a year after I was born) and apparently continued to produce watches with it until about 1992.

Seiko produced a few variations of the movement which added features such as an alarm or a calendar. For me, the purist styling of the “least complicated” 7A28 is the most interesting. The movement includes the time as well as a 30 minute chronograph. Seiko makes no movements like this today. In fact, one of the downsides of modern “re-issue” watches Seiko has produced in homage to vintage models that originally contained 7A28 movements, is that the modern movement they use as a replacement is a difficult to read 60 minute chronograph with a synchronized 24 hour (AM/PM) hand and a date window. The fact that Seiko has no modern analogs (pun intended) to the 7A28 makes it that much more interesting to me.

I found it humorous that Seiko themselves identified the chronograph accuracy of the 7A28 as “5/100 of a second.” I am pretty sure that I learned in elementary school math one should more accurately “reduce” that number to saying 1/20th of a second. Oddly enough the watch says “1/10 S.” on the dial (which refers to the purpose of a sub-dial) which makes things a bit confusing. Understanding how the movement works requires playing with it. I might need to do a video about it, but I am sure there are videos online. In short, the movement has a split second chronograph feature, and even though it is quartz, the chronograph seconds hand sweeps. It is a very handy and interesting movement – even by today’s standards.

The real watch nerd part of the 7A28 is that it eschews almost all the major complaints mechanical watch lovers have about quartz movements. The 7A28, unlike many other quartz movements now as well as back then, was not designed to be disposable, but rather durable, dependable, and serviceable. Made entirely of metal (that means no plastic parts), the movement includes 15 jewels and can even be regulated for better accuracy by a watch maker. I believe the battery life is about two years on average. When the battery life is low, the seconds hand skips a step passing two seconds at a time in order to indicate the battery needs replacement.

    Nice review. I am usually not a fan of such color scheme, but here black + gold seem to work well. 7A28 deserved its place in the history as one of the best raw performers, robust and build like a tank (Swatch Group, do you hear?!). Personally, if I was considering a watch based on 7A28, I would be searching for Seiko 7A28 RAF Gen 1 in best possible condition. The watch with real military roots, and very underappreciated (image courtesy of Brandon Cripps):

    Believe me, these watches will cost more in some time. And I think Seiko are missing the opportunity with this legendary gem. Well, they still have much to learn from the Swiss how to milk the heritage cowy 🙂

    • Lincolnshire Poacher

      Love those RAF issue seiko chrono’s. They’re not cheap though.

      • Mikita

        True. But worth it IMO.

      • MeaCulpa

        The Pulsar, that was also issued could/can(?) be had for cheap thou.

  • R.O. Ferrer

    now this is a watch. so pretty.

  • I like it! It even follows the classic “8 font minimum” Seiko rule!

  • Framlucasse

    A very good looking Seiko, despite the five lines of litterature. It’s more modern than 90% of the new watches I see here and there.

  • #The Deplorable Boogur T. Wang

    Very cool watch.
    The things you can find nowadays!

  • Sheez Gagoo

    I really would like to judge this watch but a massive hangover prevents me from doing it.

    • Mikita

      I usually take some aspirin and korean anti-hangover soup 🙂

      • Sheez Gagoo

        Thanks. Moonshinepalinka is a killer.

        • Mikita

          I should try this 🙂 last time I almost died when I mixed our native Krambambulya with Belgian ale.

          • Sheez Gagoo

            I’ll look up the recipee for the soup and then I go to the weird smelling Asia shop.

      • Sheez Gagoo

        I use Aspirin and Vichy Celelestin. A almost salty high mineralized water.

        • Mikita

          Good choice. Korean hangover soup has plenty of B-carotine + fats, which also help to survive

  • Word Merchant

    Interest watch. Just in case anyone from Seiko is reading this:

    PLEASE REISSUE THE POGUE

    • Phil leavell

      I believe it was reissued this year.
      Myself I prefer the Vintage 6139 6002. Vintage face fades to a beautiful iridescent gold color.

      • Word Merchant

        You’re kidding? I can’t find any evidence of this so please post link!

        • Phil leavell

          No worries I’ll find it again I believe it was re released or talk of it in March 2017 I’ll go and look for the link again you’ll have to bear with me I’m a little bit old and retarded it takes me time

          • ConElPueblo

            I guess you might be thinking of the 62MAS, which was reissued earlier this year? The only chronographs that have been reissued are the Giugiaro ones.

          • Phil leavell

            Thanks for the lead . I appreciate it !

        • Phil leavell

    We have had the Hodinkee effect, and now I predict the ABlogToWatch effect. A bunch of people read this, put their old quartz watches on eBay like anyone wants them, and drive down the prices.

    • Pete Pete

      you might be right. it’s too early. we’re not at that point in history when the quartz era gets appreciated as something special. at some point the great ones from that era – like the 7a28s – will get more appreciation, but they most certainly will never become a craze. they went from quite expensive when they were new to recycling value within ten years, stayed there for another ten years and since then are recovering in slow-motion towards low three digit values. and somewhere in the three digits, that’s the end of the journey.

  • SuperStrapper

    “…I do find myself interested in older watches that interest me…”
    “…but good lucky trying to find one like mine…”

    Let’s go ahead and edit some of this.

    But seriously, I had a customer years ago that was desperately trying to employ me and a few others to find him an example forbthis exact reference. Well, I say exact but apparantlybthe font for “titanium” on thw dial changed at some point and one version or another is harder to find than the other.

    Regardless, the black and gold combo, while striking, is not my cup of tea. Your find does appear to be basically untouched, can be uncommon in vintage Seiko watches. If you ever change your mind I have instructions somewhere on how to size those bracelets.

  • Yan Fin

    Congratulations Ariel! Enjoy in good health. I am definitely feeling your joy of finding something of personal sentimental value.

  • BNABOD

    Glad you found what you were looking for. Not for me, but to each his own and this is why this hobby is fun. I think Seiko has offered over this years a lot of cutting edge products and they certainly do not really milk it to death like the Swiss even though we have seen quite a few reissues of past models recently. Part of their appeal is price so you do t really get burned if you end up w a dud.

  • Pete Pete

    it’s not a looker – none of the 7a28s are – but still one of the great classics of the quartz (/seiko) era. love it.

  • TheChuphta

    Interesting. I’ve also found that I find myself interested in watches that interest me when I find them.

  • Randy Piscione

    I have the black and gold titanium version, have worn it nearly daily since I bought it new, mid-1980s I think. I send it back to Seiko (Canada) every few years now for a refresh (it’s currently in need) and I’m searching for a replacement original watchband, but it has been motorcycling, mountain biking, in-line skating, and tossed into creeks and rocks and all sorts of other things and still continues to work.

  • mark

    That’s a nice watch. My old Tissot does exactly the same thing with the second hand to inform me it needs a new battery.

    • Moonraker

      I think it’s called end-of-life (EOL) indication. A lot of quartzes have it. I don’t know if Seiko came up with the idea originally.

      • egznyc

        Not quite the same as ELO, though close in time/same era.

        • Moonraker

          Or AOL, which has reached its EOL. 🙂

  • Michael Plant

    I had a real aversion to PVD/DLC watches and quartz in general (have owned a Citizen Eco-Drive Promaster Tough since 1998, though) when my father bought an identical watch off a retired Canadian Air Force pilot a few years ago and gifted it to me. It’s been worn but is minty. I was blown away by how attractive this little watch is in the steel. Made me reevaluate black case coatings in general and I now own an SBDX011; one of my favourite modern divers.

    The only thing that keeps me from wearing the 7A28 is that at some point someone reinstalled the tachymetre rehaut upside down (120 at the 12 o’clock position and the 60 at the 6 o’clock position). I plan to send it off to Seiko Canada for a servicing eventually – and to correct the rehaut!

    Gorgeous example, Ariel. Thank you for the review.

    This watch would be a complete showstopper at the next HODINKEE Collectors Summit. As you know, only the coolest guys from all over the world attend this event, and this Seiko would clearly amaze them all. I guarantee it!

  • TrevorXM

    Well let’s be honest — the reason these quartz watches are so hard to find is because so many were thrown in the garbage when the owners got tired of them or something went wrong with them. Even though the quartz movement was decently constructed, it’s just a Seiko. Unlike “dad’s old Rolex” which were serviced and polished up a little and got a new crystal and seals if it needed it. And if “dad’s old Rolex” didn’t get some maintenance, it knocked around in the kitchen junk drawer for twenty or thirty years and was never thrown away because it was seen as a thing of value. And sure as hell, suddenly today that beat up old junk drawer Rolex is worth tens of thousands for no good reason that makes any sense whatsoever — other than it’s a real watch that was well made without corners cut and wasn’t pushed to strip mall dwellers. Integrity is the word.

    • Mikita

      Watches are funny stuff. You could find an Omega watch on a garage sale in the end 80s / early 90s, while today they command Rolex prices. I remember my father had some crappy digital Omega like this: https://uploads.disquscdn.com/images/b5199feb401031a8f031d84fe9c0e53362926c34fc691e1cd2da642ab67c8057.jpg
      Who knew that some nerds would pay so much for them now?!..

      • TrevorXM

        I’m sure that 95% of all those are in landfills. Even in spite of the Omega on the front.

        • Mikita

          There are some guys asking ~$1000 or above for these 🙂 I think Rolex Oysterquartz is miles better: https://uploads.disquscdn.com/images/f7290f827f0436f7ccd0f2018045bd5c78201dc1f1e29079d8559f0b2fc31aa5.jpg
          *maybe not two-tone

          • TrevorXM

            There certainly are some old quartz watches which have legit reason to have value. The Oysterquartz is one. And speaking of Seikos, the “Tuna” is another. But the reason why they are worth something is because of their integrity. The Oysterquartz was built to be the best quartz watch and “raise up” the technology to a standard, not build down to a price. The Tuna was built to be the best diver Seiko could build, packed full of original ideas. These watches were not aimed at the lowest common denominator strip mall watch store buyer. And though the Tuna is a Seiko, none were for sale in any common Seiko store in small city/town USA.

    Great article Ariel.

    Black and gold is not my choice of palate, but it’s a great looking and sized watch.

    For the record, your watch was produced in March of 1983.
    Also, the 7A28 actually began production late in 1982. I have an example from November of 1982, and I have heard of examples from October.

    “aBlogtoWatch reserves the right to remove or modify comments”

    Remove all you want but I want to go on record as being vehemently opposed to you modifying people’s comments. I know you want a more civil community, but editing someone’s words is wrong and two wrongs will not make a right. A person’s words should be challenged if they’re objectionable, not changed without his or her consent. I consider that an attack on a person’s dignity and integrity, regardless of the original content of the post. I believe it also damages the integrity of the person editing the post. I urge you to reconsider that part of your new policy for fear that if you go down this road too aggressively you’ll end up as just another Hodinkee.

    • Lincolnshire Poacher

      I agree with you. But just to play Devils Advocate. What I think has brought this on is the out-right racism that entered some posts last week.
      Now when I see racism, I just think; “I wonder what inadequacy they’re trying to hide”. The fraction of a second I think “loser”, is all the time I waste on them.
      Unfortunately, on the other hand, I think ABTW could be in line for some serious censure, if not prosecution if it allows blatant racism.
      BUT, ABTW definitely shouldn’t use these powers just for things that are off-message; or on the other hand, are just the normal insulting way many of us talk to each other.

      • Mikita

        I can add here another frustrating experience connected with some using the ABTW comment section as a platform for his dirty advertising tricks. I am talking of the smart buckle guy. It was pretty obvious that the guys was creating fake accounts to praise his merchandise and after being uncovered – he didn’t stop, no – he continued this circus. I think this is the obvious case when moderators must take some measures.

      • Moonraker

        OK, if they think something is racist then they should remove it. Although I don’t love having my own comments removed (like a John Candy/Steve Martin gif which wasn’t removed simply for being silly and a little off-topic but was clearly removed for being super-duper-racist :)), I said my main problem was with modifying someone’s comments. I just think it’s wrong. And you might not even know that your comments have been played with. At least when they’ve been removed you can see that little red box…hard to miss. I don’t know if there is a box that indicates outside editing.

        And despite not liking it when it’s been done to me, this complaint is not just for selfish reasons. I think it’s wrong to do to others (to commenters I agree with and to commenters I don’t agree with) and I think it could lead to real resentment and fewer visitors to ABTW. The immediacy of the comment section is a big draw to this website, for better and for worse. And like I’ve said, they should remove the worst of the worst, but they really have to stay on top of it. I know they’re busy but I’ve seen a couple of examples where it seems like they just scan the comment section before taking action:

        1. First commenter flies off the handle, horrible language. Second commenter quotes first commenter. Boss comes in and lays into second commenter, nothing to first commenter.

        2. Commenter says other commenters are so rude they should be put on a boat and torpedoed, i.e. murdered. Boss comes in and praises commenter for being committed to keeping the comment section positive.

        Then there’s a certain author, who clearly hates a certain commenter. And when commenter provides his customary lists of watches he’d rather buy, author takes it as existential insult to all the hard work he puts into his articles.

        I love ABTW but I don’t know if I trust them to moderate without emotion or personal feelings getting in the way. Deleting/modifying comments by people who criticize them, annoy them, etc…it seems to already be happening. I complain because I love it here and I want it to be a better place, just as they do. But I happen to think some of the ways they’re going about things won’t help. But I hope I’m wrong.

      • Pete Pete

        I didn’t notice any blatant racism here (during european business hours). yes, one particular user has a very dark sense of humor. snowflakes would call that racist for sure, but who cares? those people have no sense of humor whatsoever and are offended by anything all the time anyway.

        and even if it was genuine racism, still: who cares? much better if racists are straight forward with their own stupidity, makes it much easier to avoid them. and why would anyone be offended by something an idiot says? that’s something I just don’t understand.

        • Lincolnshire Poacher

          I think you’ve read past my point. Personally I couldn’t care less what some saddo thinks. My point was that in these snow flake times ABTW can be censured for allowing such comments.

    • Personally I think that if a comment violates what ABTW thinks is acceptable they should delete it entirely. Or edited to say “Content deleted due to violation of terms of use”.

      • Moonraker

        Seems fair enough.

    • David Bredan

      Thank you for your feedback, we’ll clarify that segment. We of course have absolutely zero motivation to get into modifying people’s comments, and even if we were forced to, we’d say something like [removed by moderator] or something like that to make it very clear.

      • Dinkee, H. O.

        I have had comments of mine modified in the past. Which is why I chose to take an absence in protest from my efforts to improve this blog.

        • David Bredan

          That is the single lamest effort to make us look bad. Try again.

        • Sam Anderson

          To be honest, I’ve never understood you, or many of your comments here. Serious question: are you a parody of something? Perhaps the Hodinkee site? I’ve never read anything on that site, and so perhaps that’s why I don’t get it. I don’t understand comments people make about it either. Care to enlighten me?

    If you think of anything such as a true democracy you must be a fan of Science Fiction / fantasy. Frankly I enjoy this blog try to do my best to play Within the rules thanks to all

    Hey cool! Finally an article where I can say “look at mine!”
    Mine has a stylized racer’s helmet on the clasp with the wording “Speedmaster” under it.

    I spent less than 20usd on it on a flea market, plus 10 for a crystal and battery change on a jewelry. It’s no longer water resistant though 🙁

    Very retro-future watch!

    (Typo in the first paragraph “I do find myself interested in older watches that interest me”.)

    Ahhhh yes….I remember this watch very well!! I tried to find one at local AD’s for months before I finally gave up and got another classic Seiko…a Seiko Moon Phase watch. It is, what they would now days, a “Gun Metal” grey with two tone Gun Metal grey and gold bracelet. Still have it in a display case with my other vintage watches I have always been a big fan of Seiko….and it’s nice to see vintage [pieces like this one!! Thanks Ariel!!!

    I love the dials of these old Seikos. Very simple and legible, reminiscent of a far more famous watch.

    WOW this one looks very good, Love the shape and colors, I think a new release and modernization could be very interesting!.

    If I found one in this condition right out of the box, whats the average going rate? Sure its rare, but after all it is a quartz Seiko…
