    Old? Seiko mechanicals. Hi. Q.?

    These 2 cheap purchases have appearance and feel of high quality. Never saw 3 sets of jewel shock mounts any where else. 1960? Opinions?
    Pressmatic means push to set date. Bellmatic is very loud melodic bell sound far nicer than any other w.w. alarmer. It is kind of fat to accomodate date and alarm system. Tried Seiko WUS forum in Nov. without much response.

    Very nice. I don't collect Seikos (yet) and don't know much about them. But you might like this site about bellmatics.

    Thanks for really fine interesting reference. Learned 27 jewel is rare; most are 17, and waterproof marking means before 1970. Also how to reset alarm scale accuracy. Amazing variety of Bellmatics up to 1977.

    From the Seiko date calculator

    The bellmatic comes out as "Production date Jan, 1968."

    You don't show the serial # of the Pressmatic but you can enter it yourself!

    They both look great. That Bellmatic would make a great birth year watch for me!

    Thank you for posting two very nice examples. I am far from being very technically knowledgable but I am struck by the enormous number and variety of movements produced by Seiko. I realize that there are myriad Swiss movements but, and I'm certainly open to correction on this, there does not seem to be a single manufacture with comparable variety. It makes the brand all the more interesting to me.

    The Seiko Bellmatic has a Cal. 4006A:

    The other has a Cal. 5106A, a review of which can be found here:

    heres a great resource on all the Seiko varieties courtesy of the much missed isthmus

    presmatics are definitely regarded as high quality, while bellmatics are more 'utility' watches and utilize 'work horse' movements. multiple shock protected jewels were a very common feature on mid to high end seiko movements of the time.

    thanks,

    Wonderfull references. Amazing variety. Clearly Hi. Q. as I asked. Confirms my opinion. Very interesting. The more I know the more I know how little I know. I will be paying better respectful attention To old Seikos.

    I'm sorry but the Seiko date calculator does not work, it has wrong "guessed" informations. For instance, my Monster was produced in 09/2009, but the calculator shows it was made in 1999, my mini sumo was produced in 2008, but in the calculator it shows 1998, no further explanation needed.

    All ou have to do it to see the serial number in the caseback, the first number is the year of production ( you will have to guess the decade ) and the second number is the month it was produced, the rest of the numbers are for internal (Seiko) information.

    Hope it helps, see you around.
