Machinery and weather

Mechanical watches are faster in cold weather.

No matter how long the error of the mechanical watch is, if the error is very unstable and irregular, it is likely that it is "magnetic" that leads to inaccurate travel, and it is best to send it for degaussing.

The speed change of mechanical watches is also related to the environment. According to the principle that an object expands with heat and contracts with cold, when the temperature rises, the hairspring that controls the accuracy of the mechanical watch becomes longer, the swinging frequency slows down, and the slow difference increases, and vice versa. So generally speaking, watches go slowly in summer and fast in winter.

Extended data:

Maintain common sense:

1, when wearing a watch, the sweat on your hands is corrosive to the case, so always wipe the case with a soft cloth. When you don't wear a watch, put a plastic watch holder on it.

2. Don't open the back cover of the watch at will to avoid dust entering the movement and affecting the normal work of the watch.

3. Don't put the watch and mothballs together in the wardrobe, lest the watch oil go bad.

4. Don't put your watch on equipment with strong magnetic field, such as mobile phone, stereo, TV, etc. , so as not to be affected by magnetization.

5. For watches that are not worn for a long time, wind them regularly once a month, so that the parts will not be in a static state for a long time and the lubrication of the movement in the watch will be ensured.
