Rotor
A rotor is an essential part in automatic (self-winding) watches that helps keep the watch running without needing to be manually wound. It's a weighted piece that swings when the wearer moves their arm, converting this movement into energy that winds the watch. Think of it like a mini windmill inside the watch that captures energy from everyday movements. When watchmakers mention rotors in their experience, they're talking about their ability to work with automatic watch movements, which are more complex than manual-wind watches. The term might also appear as "automatic winding system" or "oscillating weight" in job descriptions.
