Why does your mechanical watch always running faster or slower?

Many people's mechanical watches are either fast or slow. As long as you pay attention to the following matters, your watch will provide you with accurate time for a long time.

Swing violently

The balance wheel of the mechanical watch is constantly rotating rapidly. Under normal circumstances, its swing is very accurate at 220--320. If the arm swings violently, the balance wheel inside the watch will also intensify the swing. Once the balance wheel exceeds the rotation tolerance range and the swing exceeds 320 or 350, it is easy to strike the pendulum phenomenon, and the running time will be inaccurate.

Therefore, when wearing a mechanical watch for strenuous exercise, it is best to take it off.

Magnetized

If your watch is often placed with your mobile phone, then you should pay attention, because the mobile phone has strong magnetism, which can easily make your watch magnetic. Once the watch is magnetized, the swing of the balance wheel will be very small, and the time will be fast and slow.

Therefore, the watch must be kept away from anything with magnetic properties.

Cleaning and maintenance

The time is inaccurate. It is indeed a very troublesome thing for people who rely on watches to see the time. The average daily error of automatic mechanical watches is within +/- 15 to 30 seconds. It is normal.

A mechanical watch is also a small machine. It rotates indefinitely and does not stop. After a long time, the lubricating oil in it will dry out, and the movement will be somewhat dirty, which will cause the swing of the balance wheel to drop below 200, and the running time will also be inaccurate.

Therefore, the mechanical watch has been used for a long time and needs to be cleaned and maintained.
