BWCMG Watch Parts Database

The Guild is pleased to announce the opening of the new Watch Parts Database. This free tool allows you to manage your parts stock. On top of that, you can share your parts with others. If you are a watchmaker, a parts seller, or just someone who bought a lot of parts on eBay, it doesn't mattter.

Just register, and you are ready to go. This site is also a great management tool for watch parts, no matter if you want to sell parts or not. You can mark your stock as hidden, or set minimum stock levels for yourself. With unlimited amounts of hierarchical stock locations, no part will ever get lost again in your workshop (unless you drop it somewhere and you can't find it.
