    Seiko Analog Quartz Table with Pictures

    I have not been able to find any summaries of early Seiko analog quartz calibers so I did a compliation of available sources and added pictures of the watches in my collection. The bracketed figures is accuracy measured in seconds per month unless otherwise stated. I have also added additional caliber designations, such as "36SQC" and a few bits and pieces of additional information that I thought might be interesting.

    The period chosen is from the introduction of the Seiko Quartz watches until the end of the "Golden Era" of Seiko Quartz development in the beginning of the 1980s. With a few exceptions, Seiko never again tried to achieve the accuracy of the quartz watches of the late 70s and the early 80s.

    The information in the table is not always consistent in the different sources so I have chosen the most reasonable where possible and listed the differing information where it has no been possible to choose. The dates stated below is the initial year of production for a series and certain calibers within a series may have been introduced in later years.

    Unfortunately, the formatting on this and other fourms does not allow for tables or great legibility but I will try to make an excel version at a later time when corrections and additional information is available. Any corrections, comments or additions are very welcome posted to this post or sent to me by email. I will try to update the table whenever additional information so merits.

    Thanks! Nice info compilation. I've never seen anything like it on the net... This should be useful when looking for HEQ Seikos.

    You need more than just a great design. You need to create an atmosphere around the product.
    Who is the company behind it? Why are they using this material?
    People need to be able to identify the watch with themselves. It's based on emotion." - Ralph Furter

    ...that's just my opinion and I've been wrong before and will be again and might be now!

    Many many thanks Martback. I know I will be referring to this table often.

    Great work and that Superior Twin Quartz box was super cool!

    That is a fantastic post. Thanks so much! (Great collection, too! )

    Jim and I have to get on the stick some time soon and start putting new threads in the "Meritorious Threads" or "References" stickies. This is definitely one of them.

    Re: Seiko Analog Quartz Table with Pictures

    Wonderful post Martin. If possible I would like assistance on determining the initial production date for some of the other "early" Seiko quartz caliber series -- especially 58, 71, 78 and 82. TZ has a Seiko caliber table, however it does not include quartz. Perhaps the first reference (Seiko Quartz Table) cited for your post would provide the info but I can't figure out how to translate it (the first column is apparently the year from 1969 into the 1990's). Any help would be greatly appreciated.

    Hi Gary,

    in the Japanese table, the first column is the year of intriduction and the second is the caliber number. The table is not complete but is usually has the first caliber of a series. As you can see, none of the caliber series that you have is listed in the table, nor do they appear in any of my Seiko books. I found a few examples of the 58 series on the web and that looks like a mid 70s caliber. I will search a bit more during the weekend and see what I can find.

    Re: Seiko Analog Quartz Table with Pictures

    Thanks Martin. I've seen a couple of cal 5856 KQ on the auction sites. Also cal 8223 and 8229 that look more 1970's than 1980's. I have a "type II" with the symbol on the dial for quartz 7123-8100 with an S/N beginning with 8. It looks 1978 rather than 1988. Any help is appreciated. I've just started buying the vintage Seiko quartz a couple of months ago and have become very interested in them (have 11 so far). Gary

    Re: Seiko Analog Quartz Table with Pictures

    Update - Type IIs like the 71 and the 75 series are usually late 70s (77-79). gmtplusnine did a good post on these; http://www.gmtplusnine.com/2008/06/0...ce-of-history/. I found a 78 series on this page http://www.mr-coo.com/battery/seiko/seiko.html which also looks like late 70s (79-80). This site is in general a good source of info for 70s and 80s quartz watches with lots of pictures. Finally, the 82s, which I think are often SilverWaves, I would put at 1980-81. As long as you get the starting point more or less correct, there should not be any major problem in dating from the serial number as none of these watches would have been produced for 10 years.
