How to tell when your Seiko watch was made (Part 2)

closeup (Small)

In my previous article on how to date your Seiko watch, I mentioned the nifty Jayhawk’s Production Date Calculator. In most cases it should return the correct date of manufacture.

However, there are circumstances in which the calculator may give you inconclusive or erroneous results. Or no results at all. When that happens, I would resort to what I call “dead reckoning” or rough estimation.

Dead reckoning is similar to navigating your way at sea by orientating yourself with the heavenly objects like the sun, moon and the stars. You won’t be accounting for wind conditions and at best your estimate may be a few miles off your actual position. That’s when a GPS unit comes in handy! 😉

Manually estimating the production date of a Seiko involves the element of anachronism. What is anachronism? Basically, it is the utilization of an event, a person, an object, language in a time when that event, person or object was not in existence. In other words, an anachronism is something that occurs out of its proper time. The chronological error of an anachronism can occur in either direction; it can result from something from the past being represented as if it belonged in the present, like an archaism, or it can result from presenting something at a time before it actually appeared, occurred, or existed.

And anachronism is the key to manually estimating the production date of your Seiko watch.

An example would be saying that a digital LCD watch was produced back in 1964 or claiming that old Kinetic watch in your drawer was purchased in 1983. Or an eBay seller proclaiming a vintage Seiko 7T59 quartz chronograph as a brand new model from 2003. In actuality, digital watches were only commercially available in the middle of the 1970s. Seiko Kinetics, originally branded as “Auto Quartz” and “A.G.S” (Automatic Generation System) only appeared at the end of the 1980s. As for the prized and short-lived, rare 7T59 chronograph models, they were only made between 1991 and 1993.

Putting it in another way, it’s like saying the iPhone was already available in the 1990s or Microsoft Windows 7 users were running the operating system in 2004 (neither are true!). Eagle eyed movie buffs are quick to point out anachronisms in movies and you can read about them under the “Goofs” section for the movie title in the Internet Movie Database.

OK, now that you basically know what an anachronism is, let’s learn how to date your Seiko watch manually!

To perform a dead reckoning dating of a Seiko watch, the five things that you need to know are:

  • History of the caliber
  • Reference number chronology
  • Watch markings
  • Watch design
  • Signs of aging and wear

History of the caliber

Knowing when the caliber was first made and ended production would the first useful clue.

A very straightforward example is the 7002 automatic diver which was introduced in 1988 to replace the aging 6309 model whose production years ran from 1976 to 1988. The 7002 had a market life span of eight years and was shelved by mid 1996 (replaced by the current 7s26 caliber). Therefore all 7002s couldn’t be made earlier than 1988 nor later than 1996.

Another good instance would be the famous 6138 and 6139 automatic chronographs. Seiko introduced these robust and workhorse calibers in 1970 and 1969 respectively. Neither calibers never made it to 1980 and to my best knowledge, Seiko ceased making 6139s between 1978 and 1979.

Why were they discontinued? My guess is these calibers were getting more costly to manufacture and at the same time, Seiko wanted to push its quartz technology to the watch buying public. Maybe at the time they thought that mechanical chronographs were obsolete and quartz was the way to go.

The discontinuation of the 6138 and 6139 movements also unfortunately spelt the death of affordable Seiko automatic chronographs, much to the disappointment to Seiko mechanical watch fans. Currently, Seiko only offers automatic chronographs for its higher end lineups, such as the Brightz (caliber 6s28), Prospex Flightmaster (caliber 6s37) and the “Rolls Royce of Seikos” – the magnificent Seiko Credor (caliber 6s37).

Complications in dating a Seiko watch will arise when production of the caliber hits 10 years or longer. Generally, Seiko doesn’t continue making the same caliber for longer than 8 years unless the caliber itself is profitable to manufacture or it came up with a replacement caliber.

Take for example, the 7T32 alarm chronograph. It first debuted in 1988 and was discontinued sometime in 2002. Therefore, if the a 7T32’s serial number starts with “1N”, you could narrow it down between 1988 and 2002. It cannot be 1981 because this caliber wasn’t available yet! Neither can it be 2008 because the caliber was already discontinued six years earlier.

This unfortunately leaves you with two possibilities – either November 1991 or November 2001. Obviously, this is not going to be very helpful because the correct year of production has to be either one of them but not both! Try to enter the caliber and the serial number into the Production Date Calculator and it will assume that the watch is from November 1991.

So how do you determine which is the correct production year? We take a step further by knowing the chronology of the watch’s reference number.

Reference number chronology

When faced with the above dilemma, the next logical choice would be to know the chronological order of the model. This is not easy to tell unless you have seen photos of models of the same caliber to serve as reference.

Early Seiko 7T32s have reference numbers beginning with “SDW” and followed by three digits while the last 7T32 models ended with “SDWG” with two trailing digits. The digits start from the lowest order to the highest order. When Seiko runs out of reference numbers, they would append a new alphabet starting with the letter “A”.

In this example, a 7T32 model with the reference prefix “SDW” obviously predates one with a “SDWA” prefix. In the same manner, a model that has the prefix “SDWF” would be a much later model than a “SDWB” and so on.

If you are able to determine that your mystery watch has a reference prefix e.g., “SDWF”, you can be sure that your watch is a late model 7T32. Therefore your watch would be a November 2001 production and not from 1991.



Three 7T32s arranged in chronological order. The SDW379P (left) predates the SDWA65P (middle) while the latter in turn, predates the SDWC02P (right). Pics courtesy of

The same model numbering convention holds true for other Seiko models. When the company dropped the 7T32 caliber in the early 2000s and replaced it with the 7T62, it designated the first batch of 7T62s as the SNA-series. As mentioned earlier, Seiko assigns a running prefix number for its new models until it runs out of numbers. Thereafter, it would append an additional character into the reference prefix, starting with the alphabet “A”, as in “SNAA”.

Six years have passed since first SNA models rolled out the factory assembly lines and at the time of writing, the most recent models have the “SNAB” prefix. In a few months from now, you’ll find 7T62 models with reference letters starting with “SNAC” and perhaps, “SNAD”. This will continue until Seiko decides to discontinue the 7T62 caliber and replace it with a new one. Its replacement caliber will of course, have different reference letters.

Watch Markings

When the watch’s reference number is unknown, there are certain visible clues that can help you zero in the watch’s production year. The key is in the watch markings. For instance, in the 70s and 80s Seiko typically uses the word “Seiko Quartz” or “SQ” to denote that the watch is a quartz powered model.

The 80s was particularly Seiko’s golden age for their analog quartz models. In fact, the Japanese watch giant was capitalizing on its solid reputation as the world’s largest producer of analog quartz timepieces. The words “Quartz” and “SQ” also served as a selling point and differentiated their quartz models from their automatic counterparts.

By the mid 1990s, Seiko had already carved itself a solid reputation as a quartz watch manufacturer. Seiko was churning out more quartz timepieces than mechanical ones and to the masses, a Seiko watch is generally associated with a quartz movement.

Seiko probably felt they longer needed to mark their quartz products with the words “Quartz” and “SQ” so both labels were eventually dropped. Since the mid 1990s, all Seiko watches are generally quartz by default. There are also some exceptions to this rule. For instance, the SHC015P and SHC033P divers are still marked as “Seiko Quartz” for certain export markets. I presume the Seiko company did this to distinguish them from their 7s26 automatic divers as both models have strong resemblances to their automatic counterparts.

Currently, all Seiko watches are quartz models except if the movement type is indicated on the dial. Therefore, if the dial doesn’t say “Automatic”, “Kinetic”, “Thermic”, “Solar”, “Direct Drive” or “Spring Drive” then you can be sure that the watch is battery-powered quartz. This applies to all current Seikos, from their most affordable generic quartz watches to the high end Grand Seikos.

Some vintage quartz divers come with battery change year markings on their casebacks. If the watch caliber’s battery life is rated for five years, there should be an indentation mark to indicate the approximate next battery change.

This information can be very useful in getting the watch’s production year right. The photo below shows a vintage 7C43-6020 Professional Diver’s 200m. You can see the battery change markings on the caseback ranging from 1995 to 2004. The dimple mark is stamped on the year “95” as the 7C43’s battery life averages 3 years.

Watch Design

As with fashion, hairstyles, music and popular culture, watches also undergo design trends and fads. Getting the production year right purely based on the watch design is not that easy but you can still make educated guesses if you know a thing or two about design elements in its time.

For instance, LCD watches were the craze in the mid 1970s and Seiko produced pretty good classic LCD timepieces during the era.

Therefore if you have Seiko watches looking like in this picture below, there’s the element of certainty that they were from the late 1970s to the early 80s and no later than that.

1970s Seiko Quartz LCD watches

A trio of well preserved Seiko LC digitals from the 70s. Seiko gradually phased out LCD watches with metal cases and bracelets by the mid 1980s.

Throughout the 1980s, Seiko made quite a number of analog-digital quartz calibers. The analog-digital trend unfortunately also faded by the early 1990s in favor of full analog quartz designs. Currently Seiko has only two analog-digital calibers left in its stable – the world-time H023, which is nearing its end of production life and also its latest H024 caliber.

H556-5029 7A28-702A

If your watches look like these, you can be sure that they were from the 1980s.

A memorable example is the “moonphase” display trend on watches in the late 1980s. Practically almost all manufacturers (even the Guess fashion brand) had moonphase dial watches back then.

The moonphase fad had died down by the late 90s and to my best knowledge, currently only Citizen has moonphase models in their upmarket quartz and Eco-Drive Campanola line and of course, a handful of fine Swiss mechanical watches.

7F39 7A48-5000

Two examples of forgotten moonphase Seikos from the early 1990s – a 7F39 (left) and a 7A48 (right). Seiko no longer made moonphase quartz watches since then.

As Seiko has made countless models since the last century, it is not possible to detail every possible style in this article. However you can at least scope the production year within one decade if you’re familiar with the watch styling.

As with other brands, Seiko watches also undergoes many stylistic changes over the decades. You could also browse through Jayhawk’s Watch Database and see if your watch or a model like it is listed there. Here are some additional tips that you may find useful:

  • A watch marked as “Seikosha” instead of Seiko is likely to made in the early 1960s or earlier.
  • A Seiko that has a 7-digit serial number is likely to be made in 1968 or earlier.
  • A Seiko that’s marked as “waterproof” is likely to be made before mid 1971.
  • A Seiko that uses Promethium-147 or Tritium radioactive luminous compound (instead of the non-radioactive LumiBrite) is likely to be made before the mid 1990s.
  • A Kinetic Seiko that’s labeled as “AGS” or “Auto Quartz” is likely to be from 1996 or earlier.
  • A Seiko 5 with a solid stainless steel caseback (as opposed to glass display back) is likely to be made well before 2004.
  • Some Seiko 7s26 divers, like the SKX011K were introduced earlier but were later dropped from the market and replaced with the SKX011J. In most likelihood, an SKX011K predates the SKX011J version.


Signs of aging and wear

Although estimating the production year of a Seiko watch could be done by looking for signs of aging, wear and tear, this is a very subjective and by no means a foolproof method for determining its age.

Generally, a ten year old watch or older would show telltale signs of its age in the form of case scuffs, dents, scratches on the glass and bracelet, non-working functions, faded dials, rusty watch hands, casebacks, etc. On the other hand, a relatively new watch could also accumulate those scratches, dents and cosmetic flaws, depending on the manner the previous owner wore his timepiece.

One way is to judge the condition of the dial. Watches that have lived a long rough life have a tendency to have faded dials and bezels, especially if the dial has been exposed to the sun daily for years. It’s not just the heat but the sun’s ultraviolet (UV) rays that will cause dial fading.

Here’s an example of an old SKX025J that predates the SKX025K that is sold today. The watch is non-functional and the eBay sellers sold this as a parts watch.


An early model Japan-made, SKX025J mid-sized diver. This watch was probably made between 1996 and 2001.


Manually tracing the production year of a Seiko watch can be very tricky at best. If you have a relatively little known caliber or model you may be forced to resort to estimating by the watch design and text markings.

If all fails, post a question in the Seiko & Citizen Watch Forum as there will be a few kind and helpful members who may recognize the caliber or watch model. 🙂

Thank you for you help. Did the markings I mentioned tally with an original watch. Also the slight play of the bezel across the face it actually click when I move it. Is that normal. Lastly how long approx. would a SKX013 run after wearing for a day?


Hi Mark White,

I was away on a trip to Borneo at the time you sent in your question and I apologize for the belated reply.

The 2620 is a quartz caliber from the late 1970s, but I’m not sure how long Seiko made the caliber before it was discontinued. It’s a simple gents’ watch with 2 jewels and no day/date calendar. I’m inclined to think that your watch was made on August 1978. It was fully Japan made by Seiko’s Daini factory. I’m sorry I can’t provide you with its history as it was considered one of the generic Seiko quartz watches in its time, nothing really significant about it.

hope this helps,

Thank you so very much for the info on the Seiko 5126. I don’t know how you find the time to provide so much detail to so many people but I’m so glad you do. I’m surprised to learn the watch could be valued at up to USD250 and glad I don’t have to worry about wearing it or insure it but really, this watch is priceless to me because of the connection to my wife’s dad. I will continue to wear it and pass it down to my son. Thank you again and I hope you enjoyed your vacation in Borneo!

Hi mike s,

You’re welcome. 🙂 There are very few surviving 5126 watches today compared to other calibers of its era and I didn’t know about its existence until I found that Seiko 5 Sports 5126-6010, which cost me less than two hundred dollars (US). You can’t put a price to sentimental value, therefore it would be a good idea to have your watch serviced, if you haven’t done so. The rubber gaskets would have become brittle by now and the original lubricants could have gelled up over such a long time. Have its accuracy checked and the movement regulated for accurate timekeeping too.

Seiko’s old calibers are really robust and long lasting. I’ve had two 7s26 Seiko 5s fail on me despite careful wearing, but none of my vintage Seiko watches have let me down so far.

best regards,

Very Informative and helpful site! I recently got the Seiko bug and picked up my first old Seiko automatic for $25 which I think is a bargain. It’s a 7005-8032 17 Jewel Date, water resistant, with the serial number 424664 so if I’m reading your guide correctly this would make it a Feb 1974, with production number 4664 for that month? Also has Japan -M under the serial number on the caseback. Not sure what the M stands for. It’s keeping great time and only needs a new crystal to bring it up to scratch.(Pardon the pun)
I’m busy saving now for a 1968 Grand Seiko Hi Beat:) It really is a disease this Seiko collecting! Thanks for an excellent website.Best Regards Dave Baldry

Hello! I am having an insanely difficult time trying to figure out any of the details of my Seiko. I inherited it from my Grandmother when she passed away almost 10 years ago. It is in great condition and keeps time perfectly, and I would like to know more about it. The face is signature Seiko blue, and only the word “Seiko” appears on it. “Twelve” is denoted as ||, while the rest of the numbers are only |. The back says:
JAPAN – H (and a mark like a “z” appears here)

I know from your posts that it was made in August of the ninth year of some decade, and was #2581 of that month. I can’t find any watches like it through all of my online searching, and am hoping you can shed some light on it’s story. Thank you in advance!

please tell me production date of my seiko5 with 280587 serial number

Hi Jalal,

I cannot tell when your watch was made because you did not give the important caliber/caseback codes, which are found at the back of the watch.


Can you help with info on a Seiko I got?Age,value,collectibility,etc. I paid very little but watch is only in fair condition,dirty,and didn’t run.Now after removing back cover and cleaning, everything works and it keeps perfect time. Square, gents,dress watch,steel adjustible band (SQ on clasp). Analog face; second hand; day(English-French)-date @3o’clock; SQ on face@6o’clock;no #s on face only slashes. Back:water resistant stainless steel 8123-5129 AO inside a square box 330999. Inside:adjusted five jewels Seiko Time Corp. Japan A lightning bolts. On face underwhere 6 would be: 8123-5140T and lightning bolts. Any info would be greatly appreciated. Thanks!!

Hi, I have a ladies Seiko watch the numbers are, at the bottom, 740120, then above the mov’t Japan, is 2E20-7329 RO. I hope you can tell me something about it, thanks Jeanne

please tell me something about my watch…
this is all the info that appears at the back of my watch…
WP 196050

_i dont know if its real seiko watch…
My watch is SEIKO 5 sport watch

i feel bad, coz i spend mony without knowing if its real one…

Hi acrobot,

I sincerely apologize for the belated response due to unavoidable health circumstances. I don’t think there were any counterfeit 7009 caliber Seiko 5s in its time, because there’s no record of anyone having one and describing one in watch forums. However, if you are able to take clear pictures of your watch (front and back) and upload them to the TinyPic image sharing site and reply to this comment with the link to your images, only then I can ascertain if your watch is truly genuine.

Right now all I can tell you is that your watch could have been made on Sept 1991. Seiko used the 7009 extensively for its low end models (including the Seiko 5) until 1996, when it was replaced by the 7s26 caliber that’s still being used to this day.


As many have said earlier, this is indeed a valuable and hard worked resource on Seiko and relevant stuff, amongst other. However I was wondering, if we are to date our Seiko’s the way you tell us to, how can we do it for quartz watches as there is no resource for that on the web which contains complete list of quartz movements production start and stop dates, can you help us out and create such a list from your extensive experience?

Secondly, are Seiko movements only are used in Alba watches or there are some Alba’s own movements too? And can we date Alba watches the same way we can date Seiko’s as you have taught?

Lastly, I have a titanium scuba 200m water resist date Seiko which I believe was a Japan only model, can you provide approx. production date for it?

Case number is 7N35-6100[A0] Japan A

Hello Seiko Seekers!!!
My dilemma started when I acquired a Seiko ladies watch from my mother. I don’t know how long she’s had it but she gave it to me to have it appraised. None of the places I went to gave me concrete answers because they don’t know much about vintage seiko watches. I would like to describe it to the best of my ability: Its gold toned with stainless steel back, has a small quartz or diamond in the 12’o clock(not sure), no numbers in front, only small lines, no seconds only hour and minutes hand, and the serial # is 950790, 4N00-5060 with the letters RO inside a box frame next to these numbers. Its in xcellent condition but i don’t know to turn it on because i fear that i might break it. Should I hold on to it because it’s rare or unique? or i can sell it but i don’t know its value. My Mom tells me to research about it before i make drastic and impulsive decisions. PLEASE HELP, QUARTZIMODO AND SEIKO SEEKERS!!

Hi – The Online form doesn’t appear to work at the moment. I have a Seiko 5 Sport Speed Timer (SN 290419) that I’d like to part with (Trade or Sell) in order to aquire more Seiko’s. I’m very new to the watch forums. Suggestions to it’s fair value would be greatly appreciated. I have dealt online with a lot of Muical instruments – but I imagine, there is a much more deliate protocal with watches.

regards Seratone

Hi Seratone,

Thanks for dropping by my blog and raising the question about your Seiko 5 Speedtimer.

With only the serial numbers to go with, nobody knows the model that you own because Seiko made several models bearing the Speedtimer name from different calibers.

In fact, I myself own a few Speedtimer models from the 6139 and 6138 chronograph families. You need to know the caliber/caseback details that are found at the back of your watch first.

Saying that you have a Seiko 5 Speedtimer for sale is like having a Fender Stratocaster for sale, giving only the serial numbers in the advertisement.

What year is the guitar from? Is it a pre-CBS or post-CBS model? Does the guitar happen to be the short-lived, “The Strat” from the early 80s? Is it a vintage 1954 reproduction or a Mexico made Stratocaster with a Floyd Rose tremolo and humbuckers? Rosewood or Maple fingerboard? Active or passive electronics?

It’s the same when it comes to Seiko watches. You need to be more elaborate in your description.


Its been a while since we have heard from you QUARTZIMODO , are you ok? Hopefully you will be recovering well from the health condition you were suffering from. GET WELL SOON !! 🙂

My friends asked if I could find some info on this watch. Its a quartz 4130-9001, 505413. From what I’ve gathered, it was made Oct 1975? yes/no? In it’s day I guess it was a pricy watch, how bout now? Thnx, Dennis

Hello, I have a Lassale 5Y30-5K69 RO 060242 I purchaced it new back in the late 80s or early 90s for around $300 and was trying to find out what it would be worth today.

Hi Andrew,

Thank you for the question. You can try to find out the value of your Lassale watch by searching for it on eBay. Because the Lassale series watches come in several caliber/movement types and differing metals (most are 18K gold; others in stainless steel) and in various conditions, it’s hard to say how much yours is worth now. All I can tell you is that your Lassale was most probably made on June 1990.

I’m not an expert in the Lassale lineup and the first thing I would do is find the average selling prices on eBay. 🙂


hi any info on my Seiko Kinetic 5M62 0AF0 Unique number 280720
only ever seen one other and unable to trace on Seiko website

Hi dez,

You have one of those stylish, asymmetrical cased Seiko Kinetic sports watches. The model code for your watch is SKA187P and was been made on August 2002. Seiko does not list your model on its official websites as the company makes too many models for them to list. They are not willing to go through the trouble of listing archived or discontinued models on their websites; so what you see on Seiko’s websites are generally the currently selling models.

hope this helps,

I have a 7N43-9048 with a serial# of 860254. I know nothing about it, it was a cheap 10 dollar garage sale buy. Any information on it would be great.

I have a SEIKO 5 KY 7009-3170 with serial nr 009613 can you tell me from which year is it? and i would like to know what does A2 mean after the model nr. Thank you in advance.

Hi Paul,

In most likelihood, your Seiko 5 7009 was assembled in Hong Kong on October 1990. Some Seiko experts believe that “A2” refers to Seiko’s watch case tool and the procedure required to open the caseback but there’s no real evidence to support this assumption. “A2” could also mean the watch’s caseback is a 3rd generation type (provided older versions of 7009-3170 also exist with “A0” or “A1” instead of “A2”). The only way to be certain is to ask Seiko Japan’s officials; but whether they’re willing to give the straight answer is another matter. 🙂


I have a man’s Seiko Quartz watch with white face and numbers not nurmals. It also has no date. Here is the information on back. I would like to know approx date of it if possible. Or anything you might know about it.

Mov’t Japan

Hi Shirley,

The V700-8A10 is a simple gent’s quartz dress watch on a leather strap. This watch has a Japan made movement but was assembled in Hong Kong (China). It requires a Seiko or Maxell SR616SW 1.55 volt battery which will run the watch for approximately 3 years. There’s nothing of historical significance behind this model; it’s one of the countless quartz dress models which Seiko made in the past. As such, it has little value to it and pre-owned ones usually sell between USD50-70.

Your watch was likely to be made on April 1995.

Thanks for asking!

Hi. I have a Seiko Bell-Matic with Serial Number 300772 and is 4006-6021. May I know when it was manufactured. Thanks!

Hi P Sanidad,

Your Bell-Matic was produced on Oct 1973. Seiko Bell-Matics are easy to date because their production didn’t last over a decade, beginning from 1967 and ending sometime in 1977 or 1978. I have two 4006’s myself and they’re great watches! 🙂


Hi , enjoying reading ur blog. I have a seiko 5 with serial number 2N3639 and case number 7s26 0440 , accorind to ur previous artical i can tell it was manufactured on Nov 2002 (correct me if i am wrong) . I just curious about where was the movement assembled ? Thanks in advance .

Hi CY,

Your Seiko watch carries the reference prefix SNXxxxK of which the lowercase “x” refers to digits, e.g. SNX113K, SNX115K, SNX551K, etc depending on the actual model. Early SNX Seiko 5s had a stainless steel caseback instead of the see-thru display back. As such, November 2002 is very likely to be its production month and year.

Basic Seiko 5 watches with the 7s26 automatic caliber have their movements made in Singapore (7s26A), while 7s26B and 7s26C versions are assembled in Malaysia. Regardless of the movement, Seiko 5 watches are cased in Hong Kong except for certain models that are purported to be wholly assembled in Japan.


Hello. Please excuse this question regarding a watch I bought for my son. It is a Pulsar, so I hope you can find the time to help. I bought a PF3291. It is an analog chronograph with a 12 hour alarm. I have tried repeatedly to set the alarm but it never sounds. The alarm seems to function solely as a regular watch. I bought the watch on eBay and if I mail it back for a refund I am required to pay for shipping and a 10% restocking fee.

Hi Watchmego,

I’m not familiar with individual Pulsar watches as this brand is marketed exclusively in the U.S. However, I managed to track down the model PF3291 and found out that it uses the Seiko 7T62 alarm chronograph movement. The 7T62’s alarm subdial has its own timekeeping and it can operate separately from the watch’s main time. I own a Seiko watch with the 7T62 caliber and I found that it’s tricky to set the alarm compared to its predecessor, the well loved 7T32 caliber.

Instructions on how to set the your Pulsar’s alarm can be found here.

good luck!
