The manufacture date decoder

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 and if available useful links such as manuals etc.
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 other brands, musical instruments or other collectibles try

Movement :


Thanks to all those who have donated so far, I really appreciate it. The volume of traffic means I had to move to paid servers. I will never charge to see results and dont want too much getting in the way.
