How to Find the Model Number on My Seiko Watch

Updated February 21, 2017

Classic watches manufactured by Seiko have a serial number that decodes the year and month they were manufactured, the movement of the watch and the model number. Since Seiko has produced a variety of styles, designs and brands of watches, the model number is a good way of identifying the exact make and model. Whether you need the model number to find a replacement piece for your watch or are looking to obtain an appraisal, the model number is hard to see but easy to find.

Turn your Seiko watch over so the back plate is facing up. Use a soft cloth to protect the surface of the watch from scratching when putting the face of the watch on a table. Use a light to make any engraving easier to find.

Look at the back plate and edges with a magnifying glass for a 10-digit serial number. The serial number consists of a series of letters and numbers that are engraved on the back cover.

Decode the serial number to find the model number. The last four digits will give you the model number you are searching for.
