A watch clutch is a mechanism in a watch movement that helps to keep the hands from slipping or jumping. It consists of two discs, one inside the movement and the other on the outside, that are connected by a spring. The outer disc is pushed against the inner disc when the spring is released creating a secure connection, allowing the hands to move smoothly and accurately. A clutch is often used in mechanical watches to ensure that the hands move at the correct speed and do not slip or jump.
