SERIAL-NUMBER-DECODER.CO.UK

The Seiko watch serial number decoder

Find the manufacture date of your Seiko watch.

Enter the serial number and movement from your Seiko watch in the boxes below. The date of manufacture will be calculated using the first 2 digits of the serial number and my database of movement manufacture dates. You will also be given an ebay link to check its value, useful links such as manuals etc(if available) and for quartz models the battery information.
If more than one manafuacture date is returned then either I lack the data for that movement or the movement was made for over a decade. For details of my database click here. For infomation about how this works and how to decode a serial yourself click here.

Neither boxes are case sensitive although both the serial and movement code can contain the letter S, which can look very similar to a 5. If it fails please double check that.
