NEW forum where you can help me add to my database

The Seiko manufacture date decoder

Enter the serial number and movement from your seiko watch in the boxes below. The date of manufacture will then be calculated using the first 2 digits of the serial number and a database of movement manufacture dates. You will also be given a link to check its value and if available useful links such as to manuals etc (I am currently adding these to the database).
You may be returned more than one date option, this is either because I lack the data for that movement or the movement was made for more than a decade.
