6 Maintenance guide for mechanical watches Mechanical watches work based on the power of the spring The watch is operated using the power of a unwinding spring that is wound manually or automatically. By maintaining the winding of the spring, accuracy is preserved. The spring is wound by wrist movement In a mechanical watch, the necessary time to wind the spring sufficiently is 8 to 10 hours when the watch is worn on the wrist. When the spring is unwound, the watch stops but this is not a failure Even if the spring is wound all the way, the watch stops in case you don’t wind the spring for about two days manually or automatically.
