It is normal for a new mechanical watch not to move without winding. If you hold it in your hand without the upper bar will begin to move, and keep moving up, indicating that the watch in the static movement, the clockwork is not released, the pendulum stopped swinging, held in the hand with the help of the external vibration of the right to begin to move, this piece of the watch quality is not considered to be the most good.

When the new watch stops walking, gently broadcast shaking with your hand, the second hand should start walking. Does not go, explains the sensitivity is not high; If the second hand walking time is not long, generally in one or two minutes, up to three or four minutes or less, explains the watch quality is good, in the static walking, the clockwork has been all put out. If the second hand moves in five or six minutes or more, it means that the watch is in static movement, the clockwork has not been put out of the pendulum has stopped swinging, the quality of the watch is poorer. The second hand stops after one or two minutes of movement after shaking by hand, which is caused by the higher sensitivity of the balance wheel by the staff force of shaking. The above said walking time after shaking is only a reference number, because the attenuation coefficient of each kind of pendulum is different, at the same time, this method is not the only way to judge a piece of watch, because the clockwork is loose and tight and the transmission of the wheel system are allowed to have a certain degree of fluctuation.
Therefore, even a good watch out there every time such as the phenomenon of the above measurement method is not repeated, so this method is only a valuable reference number one of the methods.
