Watchmaker tools can vary dramatically depending on the type of watches that are being built and serviced. Certain things like a loupe, screwdrivers, timegraphers, and caseback tools are all standard, but many manufacturers have proprietary tools that must be used to properly service their watches. Additionally, other tools like a lathe must be used should you need to fabricate new parts while restoring a vintage timepiece where replacement components simply are not available.
