Multisport Smartwatch

KOSPET MAGIC 4 is designed to be more powerful than the previous generation, thanks to the revolutionary design of the watch materials and manufacturing process, while remaining ultra-lightweight, the watch is very comfortable to wear while doing sports or sleeping.https://www.kospet.com/products/kospet-magic-4-smartwatch
Timing instrument of mechanical vibration system, such as pendulum clock, pendulum wheel clock, etc. Its working principle is to use a vibration system with constant period and continuous vibration. Multiply the vibration period during vibration by the number of vibrations, which is equal to the elapsed time. Time = the vibration period of the watch × Number of vibrations. It is generally composed of energy, gear train, escapement mechanism, vibration system, pointer mechanism and additional mechanism. Power -- the spring or heavy hammer provides the energy for the working of the mechanical clock. Through the growth rate of the gear train, the last bar can run continuously for many days at a time. The escapement mechanism makes the timing frequency of the clock conform to people's　second　concept. The pendulum or balance wheel controls the speed of the clock, and the time (moment) mechanism tells people: what time is the last ring just now.
