Today we’re highlighting a single repair done as part of a service. I think it’s an interesting job that involves a sleeve with 0.15mm walls.
Pocket Watch Fusee Ratchet Wheel
I recently was working on a late 1700s watch that was missing a ratchet wheel for the fusee and it’s retaining screw. There was also some damage to the locating pin and a lot of scratches on the surface the wheel would have sat on. The damage needed repairing and the wheel and screw replacing. You can see in the drawing below the wheel would be just 8.7mm in diameter - quite a challenge!
