Watch Maintenance Knowledge Q & A

1. Why do mechanical watches have to be regularly sent for maintenance even if the watch runs normally?
The mechanical watch needs to be lubricated regularly to keep it running smoothly. Over time, the effect of lubricating oil will become worse, and the friction between machine parts will increase, resulting in wear and inaccurate travel time. In addition, friction will produce very fine dust and wear the parts of the watch movement.
2. How often do mechanical watches need to be maintained?
Most are every three to five years.
3. What are the precautions for adjusting the calendar?
Please avoid adjusting the date between 21:00 and 4:00, because this operation is easy to cause damage to the watch and incorrect calendar jump. Due to different watch models, the restricted area of calendar adjustment will be different. It is recommended that you refer to your watch operation manual.
4. How to basically clean the appearance of the watch?
General dirt can be gently wiped off with the old soft toothbrush at home every few months. However, it should be noted that if you don't know the waterproof performance of the watch, you should wipe away the debris with a dry toothbrush. For those watches that clearly list the waterproof performance (if you don't know the waterproof performance of the watch, you should first go to the maintenance center for waterproof test). You can wet the toothbrush with a small amount of diluted mild soap bubbles, and then gently brush the soap bubbles and dirt with clean water. The plastic strap can be cleaned by the above method, but the leather strap should be treated with extra care.
5. How often does the waterproof function of the watch need to be tested?
All waterproof watches need to be tested every time the battery is replaced or the case is opened for any reason. That's because the waterproof gasket will fall off after the case is opened. These washers (or type 0 washers) are located in the case, at the connection between the case and the rear cover, crown and surface crystal. For this reason, when the battery in a waterproof watch needs to be replaced, it is very necessary to take the watch to the maintenance center with waterproof performance testing instrument. In some cases, the waterproof performance needs to be tested even during battery replacement.
6. Do you need to write on the mechanical watch every day?
If you do, your watch will go more accurately. If you're not going to wear a watch, you'd better put it on. In this way, the movement lubricant can be prevented from condensation. Of course, this does not apply to automatic movement or automatic wristwatch. This kind of watch only needs to be listed at the beginning to make it go. If the wearer is very active and wears it for 12 to 15 hours a day, it will always remain full.
7. When you set the watch, does the rotation direction of the crown have anything to do with it?
On most mechanical watches, there is no effect. But for some mechanical watches, especially those with calendar function, you should only move the pointer clockwise. The adjustment direction is included in the manufacturer's operating instructions. On a quartz watch, it doesn't matter in any direction. However, the manufacturer points out that the gap in the minute hand can be eliminated by setting the watch in the following way: rotate the minute hand clockwise until it is adjusted to the corresponding position a few minutes ago, and finally rotate counterclockwise to return it to the correct position.
8. If you don't wear a watch for a few days and pull out the handle of the quartz watch, you can save the energy of the battery. Is this true?
Pull out the handle shaft because the gear and pointer are no longer running, which can save energy by 75% to 80%. However, when you consider that if a silver oxide battery is left unused, it will only lose 5% to 8% of its energy every year. Finally, the savings are almost even with the rest after the loss. Another argument against using this method to save energy is that if the gears in the gear train remain stationary for a long time, the lubricant will condense.
9. Will cold and heat affect the accuracy of the watch?
Both hot and cold will affect the time recording ability of quartz watch. The extremely stable vibration of quartz crystal is the guarantee of the invincible accuracy of quartz watch. After being cut, they perform best at room temperature. When the temperature reaches 38 degrees, it slows the watch by 1 second every day. Extreme temperatures can also affect the accuracy of mechanical meters. One reason is that cold and heat will make watch movement parts expand or contract; Another reason is that cold and heat will affect the viscosity of the lubricating oil of the movement, and then affect the accuracy of the movement.
10. Can I wear a mechanical watch during exercise?
It is generally not recommended to wear it during exercise. All of our mechanical watches today are equipped with shockproof devices to protect the pivot of the balance wheel shaft, the most vulnerable part of the watch movement, which is most vulnerable to impact and damage. For example, this device is usually used to protect watches from impact when hitting tennis or golf. Nevertheless, sometimes a small change, such as a heavy bump, will not only damage the balance wheel, but also damage the rotor shaft. It is used to protect the gear train of some automatic movement.
