Sensitivity Of Watches
- Sep 06, 2017 -

The sensitivity of the watch refers to the flexibility of its balance wheel to automatically swing. The Check method is:

1 A watch that would not have been on the wind had ceased to walk, and gently shook to observe the movement of the second hand by shaking the power: if the seconds are stopped in a very short period of time, it means that the watch can be fully completed after the full winding (that is, the wind torque), high sensitivity; if the second hand continues to walk for a long time, It means that the watch can not be fully completed after the full spring (that is, the spring is also stored torque), the sensitivity is not high or the table machine is faulty.

2) will not be on the spring to stop walking the watch, slowly turn the head, observe the second hand start the situation: the less the rotation of the top, the more the first time to start the table to explain the higher the sensitivity of the meter, and conversely the low sensitivity or other failure of the table machine. But pay attention to the rapid hand-waving table by Yu Yings stiffness, than the traditional frequency (18,000 times/hour) of the table confidential more than a little wind-up to play. A watch with a high sensitivity has a longer time to move after a full spring.

Between the hands and the table mirror, the dial and the three needles should maintain a certain spacing, otherwise each other produces rub and affect the normal operation of the table machine. The examination can be observed by dialing the needle. The position of the hour hand and the minute hand and the coordination of each other is normal check method is: The minute hand and the hour dial to 3 points, 9 points, to observe whether the two needles are at right angles, dial to 6 points, two stitches into a straight line.
