Bump. O:)

Please humour me on this and show me or tell me about the "newest" 7 digit Seiko case back you have, please. :-*
Ah, you mean the oldest. I was going to post a newer model that went into production 2009 and I have seen a 0 dated caseback for this year (no pic sorry).

I have seen this on Yeoman's weblog - SKZ283 model "Starfish"

Sorry i mean a 7 digit serial number instead of the newer 6 digit # they were last used in the late 60s i believe.
So after 5 minutes of going through all my late 60's watches not one of them has a 7 digit caseback #, so now I need one.


Thanks thread....
I would be interesting in knowing why there are so many six digit serial numbers prior to 1970. ???

I'm a little suspicious of that 6105 caseback. From what I've seen, everything coming out of Suwa after mid 1968 was six-digit . I've seen several 7-digit serials on 8000/09s to that period (and there have been a few posted here in the past and one on the database). I wonder if that caseback is a service part, but I'm not sure how that would explain the serial number. There were certainly watches that date before the one you've pictured, made at Suwa, that have six-digit numbers. A puzzle.....

EDIT: Sorry, but I meant to write that I have seen 8000/09 casebacks to mid '68 (I was double-tasking -- always risky when trying to post....) I've amended my original post. Hopefully someone who has seen a lot of these in hand will reply (Mike? Rick?)

Great stuff Russell but disappointing i thought my January 1969 was the latest one !! :'( :) :) 8)
Cheer up young fella, Does' it mean ? Example your Jan 1969 ends with the #s --300 and my Jan 1969 ends w/# 391 Does that mean that Mine
was 91 Watches latter, is That how the Numbers work?????
No Russell the last 5 numbers are how many were produced in that month alone.

Well John i do know that the Belles in general only had 7s in 1966 and 67 then changed too 6.

I think from what i can make out the only thing you can be 100% sure about with Seiko is that you can not be 100% sure !! ;)
