Here’s a great database where you can load in information on watches, and an AI tool automatically searches for the parts across the web.
It doesn’t have every source…but a lot !
It was created by a lovely watchmaker named Emmy. She lives and works out of Halifax Nova Scotia
It can be a bit “wonky” at times,..so you might have to start at her homepage and then click on the Watch Database tab in order for it to work correctly
