Description

Technical Field

[0001] The utility model relates to the technical field of movement clamping, in particular to a clamping device for processing watch movement. Background Art

[0002] A watch, or wristwatch, is an instrument worn on the wrist to tell time and keep track of the time. A watch is usually made of leather, rubber, nylon, stainless steel, etc., with a strap that shows the time tied to the wrist. The watch head is a precision instrument used to indicate time. The principle of the instrument is to use a vibration system with a constant period and continuous vibration as a standard. If you know the time required for the vibration system to complete a full vibration of the watch (vibration cycle) and calculate the number of vibrations, then the time after so many vibrations is equal to the vibration cycle multiplied by the number of vibrations. That is, time = vibration cycle × number of vibrations.
