Seiko 6105 question about serial number
 
Hi,


I'm new here, but i'm collecting watches for a while now. I do own a couple of 6139 and 6138, though.


I've recently (yesterday) acquired a Seiko 6105-8000 and i have a question regarding the serial number on the back, 8405491. Also on the back there is "Japan X". What does it means? Normally I've only seen six digits serials on Seikos.


Thank you,
Mihai

Seiko switched between 6 and 7 digits in the late 60's. Your watch is from April of 1968. I am not certain what all the various case markings of Japan X or Japan A are, it could have been a code for which line or factory they were made in. Others may have a more solid answer on this?


Congrats on acquiring a 6105-8000, please post pictures!!

Good link Gabe. There is one mistake on it though in that the author states that 'S' is used for September, when in reality September is represented by a '9'.
