Welcome to my labour of love! I’m a Seiko watch fan living in Japan and over the past few years I’ve been collecting details and links about Seiko watch movements, partly to help with repairing them, partly just out of curiosity. I’ve now made the database public here (although it's still a work in progress) so hopefully it'll be useful to other watch collectors and restorers.
Because all the data is collected by hand, it’s possible I’ve made mistakes. If you spot any, feel free to let me know using the form below.
In the meantime, a good starting place is the main Seiko movement list. You can also get news and discussion in your inbox with my free Seiko newsletter. Thanks for stopping by!
