1. The secondary outer ring of the hairspring rubs the outer column of the hairspring. In this case, it is necessary to adjust the gap between the secondary outer ring of the hairspring and the outer post of the hairspring, so that there is a reasonable safe distance between them. What if Jaeger-LeCoultre watches are not allowed to keep time? If possible, these things need to be handled by professional institutions. Don't show off yourself, lest you lose more because of small things.

2. Insufficient kinetic energy. If the kinetic energy is insufficient, you can manually wind up the spring. An automatic watch with a 24-hour error of 45 seconds at room temperature is a normal error. Because automatic watches must be automatically wound by the swing of their arms, they must be worn for more than eight hours every day to ensure accurate timing.

3, the watch is magnetized, which will also cause the watch to be inaccurate. Find an unmagnetized iron ring, put the watch in the ring and put it on slowly. After a few minutes, the watch will be degaussed and restored.

When we are wearing a watch, the watch is violently shaken, which will cause the parts in the watch to be loose and misplaced, thus making the watch inaccurate. We need to go to a professional watch repair center for testing.

5, the watch into the water will also lead to the watch is not allowed. At this time, you can wrap the watch tightly with several layers of toilet paper or absorbent flannel, and bake it at a distance of 40 watt bulb 15 cm for about 30 minutes to eliminate it. Never bake the watch directly by the fire to avoid thermal deformation.
