Default Seiko Serial Numbers

It's common knowledge the first 2 digits are year and month of manufacture.

And when the second digit is N = November and D = December

Can anyone confirm, from actual evidence, what is used for October.

When Googling there are conflicting statements.

I've always seen "0" on watches for October. Not "o" but "0" .... I've never seen anything different that I recall.

Yes, it is the zero digit for October.

that looks like an O but it's on a newer, current watch. And those are laser etched (?) as opposed to stamped so it's probably just as easy to make it correct with an O instead of a 0.

I assumed in the old days they used the 0 for an O for time/$ savings - I'm sure the N and D were extra work and why bother with the O when a 0 will do the job ...

All speculation on my behalf but seems reasonable.

Reply from Seiko UK CS,

Hi Mr *****,

Yes, October is denoted with an O not 0 (zero).

Kind regards,
Carol.
CS Dept.


Which I suppose answers the Q for modern watches and most probably mwander interprets correctly as to why.

Perhaps we can assume old, stamped, serial numbers to be 0.

I hope Martin doesn't mind:


(from here: https://adventuresinamateurwatchfett...tic-6218-8971/ )

You can see that Seiko used the same shape for October and zero.

Will be Hoping the answers are Found. Especially ser#s starting with D. For a long time it was accepted that SEIKO facts were at times not so reliable, Seiko being Seiko?? Maybe this is just one of those Times??Does not stop me from loving Seiko just would be nice to know TIA

It was established a long time ago the the 0(zero) was used for October because it is the 10th month.
Seiko seem to have forgotten that and are now apparently using O(capital O).
In the end, it really makes no difference because to most people the O and the 0 look the same.
