What should I do if the hour hand of a mechanical watch is not accurate? What is the reason for a mechanical watch to be fast?

Mechanical watches are one of the more popular types of watches. Many people will consider mechanical watches when buying watches. Mechanical watches are more collectible and more upscale. So what should you do if the hour hand of a mechanical watch is inaccurate?

When the hour hand of a mechanical watch is inaccurate, the best way is to take the relevant items to a specialty store to adjust the time, or choose a regular watch shop with rich repair experience for repair and maintenance. Due to its own structural problems, mechanical watches are easily affected by the earth's gravity, and the horizontal and vertical position deviation will cause the hour hand to be inaccurate.

1. The internal movement is magnetized

The internal movement of a mechanical watch is very powerful, but if it is affected by a magnetic field, it will not keep accurate time. The inner part of a mechanical watch is a very important part. If there is a large circle or it is adsorbed, it may be misaligned and the movement may be inaccurate. If the watch is only a few minutes fast, you can observe it for a while. If the watch is two hours faster than normal, it should be repaired in time.

2. The hairspring device is deformed

When the balance wheel inside the watch rotates, it will mostly stretch and contract. Since there is a defect in the state of the balance wheel, the stretching will be limited. If the swing amplitude is large, the cycle will be shortened. At this time, the total time of the watch will be inaccurate. The main reason is that the watch may have been hit hard or vibrated, so this situation will occur. There is another rare situation. For example, if a fine fiber is accidentally hung on the hairspring, it will also cause the watch to run too fast.

3. The watch is old

In addition, if the watch is old or in disrepair, the working efficiency of the movement will decrease, and the swing amplitude will also be significantly reduced. Therefore, the mechanical watch may run too fast or too slow. Every watch must be carefully maintained and maintained on schedule. Only in this way can the watch be worn for a longer time and the timekeeping can be more accurate. It is recommended not to wear one watch all the time, but to wear it alternately with other watches.

There are many reasons why the hour hand of a mechanical watch is inaccurate. The first reason may be insufficient kinetic energy. Mechanical watches are usually wound manually or automatically. Insufficient power is one of the most important reasons that can easily lead to inaccurate mechanical watches. The hour hand may also be inaccurate due to impact. No matter what kind of watch it is, it cannot withstand impact. Once it is hit hard, such as shaking your hands or vibrating during exercise, it will cause the parts in the mechanical watch to become loose or even scatter. Another reason may be that it is not maintained in time. After a mechanical watch is used for a long time, a lot of dirt will be deposited in the watch, which increases friction and causes the hour hand to be inaccurate.

(1) When wearing a watch, the sweat on your hands is corrosive to the watch case. The all-steel watch case is made of nickel-chromium alloy and has better corrosion resistance. The semi-steel watch case is made of copper and is easily corroded by long-term contact with sweat. You should wipe off the sweat frequently with a soft cloth or put a plastic watch holder on it to prevent it from being corroded by sweat.

(2) Do not open the back cover of the watch at will to prevent dust from entering the movement and affecting the normal operation of the watch.

(3) Do not place your watch in a closet with mothballs to prevent the watch oil from deteriorating.

(4) Do not place the watch on an amplifier, stereo, or television to avoid magnetization.

(5) Watches that are not worn for a long time should be wound up regularly once a month. Automatic watches should be gently swung back and forth for a few minutes or worn on the wrist for a period of time to allow the spring to be automatically wound up. This will prevent the parts from being in a static state for a long time to ensure the operation performance of the watch.
