The Seiko serial number database

Details of the Seiko movement database

Below is live information about the current Seiko movement database, it is updated regularly (scroll to the bottom to see last updated date). I am notified of movements which are searched for but not in there yet, when this happens I try to update it to include those missing Seiko movements. Click on the movement number to view the information I hold for that movement. Please feel free to contact me if you find anything you think is wrong or have information that is not currently in the database.

Some of the dates contained in the database are approximate but when used with a serial number are accurate enough to narrow down the decade.
