Introducing the Seiko Date Finder

Posted Feb 21, 2016

We built a calculator to help you find out when your Seiko watch was made. It includes instructions for finding your model and serial number on the caseback of your watch as well as a description of how the calculator works. We found production date ranges for hundreds of Seiko movements to help make the calculator work and we'll continue to research additional movements in the future to expand our coverage. Check out the Seiko Date Finder today!
