Mainspring
A mainspring is a crucial component in mechanical watches that acts as the power source. Think of it like a battery in a modern watch, but it's actually a tightly coiled metal ribbon that stores energy when wound and gradually releases it to power the watch. Watch repair specialists and watchmakers frequently work with mainsprings, as they need to be maintained, replaced, or adjusted to ensure accurate timekeeping. This component is fundamental to traditional watchmaking and appears frequently in job descriptions for watchmakers and watch repair technicians.
