Identification of a pocket watch part

Post by DannyO »

Hi folks. Just wondered if anyone knows what this part is called? It's a cog with some sort of chain on it that has broken. It looks a little like a tiny bike chain!

Thanks!

Dan

It’s called a fusėe and it is a device that was invented in or around the 17th century to even out the torque of the main springs used in clocks and watches at the time, in order to achieve more even timekeeping as the spring ran down.

The fusee chain snapping is a common problem and unfortunately not easy to solve. Two possibilities:

1. find a replacement chain on ebay or the like, making sure you get the end hooks. You'll need to measure with a micrometer.
2. Remove the broken link and re-rivet, a good watchmaker can do this but it will cost.

The chain snapping is usually caused by winding the fusee the wrong way, it has to be wound anti-clockwise when looking down the key or winding stem. Been there, done that - Idiot :oops:
