2, check the sensitivity of watches the sensitivity of the watch is flexibility for the swing sway
. Examination methods are: 1) with a silght shaking for the watch which can not be winded but had stopped walking in order to observe the second hand move around: if the second hand stopped moving around in a very short period of time, it indicates the watch can finish the winding (the winding torque-free) after winded,which means a high sensitivity; if the second hand to move around a long time, it indicates only full winding watch can not be completed all the post (that is winding also stored torque), sensitivity is not high or table machine is faulty. 2) had not had any winding watch stopped walking and slowly turned his head to observe the second hand start: The rotation of the article to less second hand description of the earlier start of the table the higher the sensitivity; the other hand, the sensitivity of low or table machine has other faults. But pay attention to watch as gossamer Quickly stiffness than traditional frequency (18,000 cycles / hour) on the table a little more than winding confidential to swing. High sensitivity of watches, it will walking for a long time after a winding.
