The creation and production of watches are based on a simple and witty invention, that is, "clockwork", which can tighten and store energy and slowly release energy to push the running devices and hands in the watch to achieve the function of displaying time. This spring device in the watch is called the main spring. Wearing a watch has no special significance, just to make it convenient for people to know the time and arrange their own schedules. Of course, different watches have different uses. ....
But according to the research of medical experts, taking the watch to the left hand will oppress people's nerves, which (I don't know what nerve it is) is not good for health. Taking it to the right hand is good for blood circulation and heart function. (It seems that the main blood supply artery is in the right hand. )
