As only 1 digit is used for the year this will only show you the last digit of the year, the decade cannot be found from the serial number, more on this later.

For the second digit covers up to September. So the serial number could be May , May , May , May etc.. There are visual clues as to which decade the watch may be from but the easiest way is by using the Seiko movement number, if you can find the date range for the particular Seiko movement you are likely to be able to pinpoint the exact date. It tells you the month the watch was manufactured.

The remaining four digits of the serial number indicate the production number for the watch. If your last for digits are then you have the first watch made for that model reference number. If you were paying close attention you may have noticed we asked for the case code in the form above but we did not mention using it when calculating the date.

You can leave that field blank and still find the date for your watch however if you complete the field we will provide a listing of watches from our Seiko catalogs that match the movement and case code.

What you see here is in large part thanks to this excellent Quartzimodo article How to tell when you Seiko watch was made. Unfortunately the Jayhawk Production Date Calculator by John Gauch which is linked to in the Quartzimodo article no longer seems to be available, so we built our own.

It does not seem to be as well known and we hope that our movement database is more complete and that our instructions are more helpful. As with any part of WatchSleuth we encourage people to contact us with suggestions, corrections or any other information that would make our site more useful.
