Seiko Date Tool

[andrema]

Have you ever wanted to know when your Seiko was produced? Well I have!!! I ran across this site the other day...

To find the production date of your Seiko watch, enter the movement number and serial number from the back of your watch below, and hit "Calculate". This system uses the start date of a movement and the digits of the serial number to calculate the production date. When a movement is in production for more than 10 years (eg. 7S26), the first possible date is reported.
