Seiko Serial Number Decoder

This is a great tool to use to date your Seiko. Seiko watches have a 6 or 7 character serial number on their casebacks. The second character can be a letter but the rest are all numbers. You can use the Seiko serial number in conjunction with the movement number to calculate the year of manufacture.
