Cannon Pinion
A Cannon Pinion is an essential part in mechanical watches that helps show the correct time. It's a small tube-shaped component that fits in the center of the watch and connects to the minute hand. What makes it special is that it can turn while staying firmly in place, which is crucial for accurate timekeeping. When watchmakers mention this in their experience, it shows they understand the core parts of watch movements. Think of it like the middle gear in a bicycle that helps transfer power from the pedals to the wheel, but for watches.
