What should you note when servicing a mechanical watch?

　　For a mechanical watch, it is recommended to carry out appropriate maintenance every 1 to 2 years, which includes replacing water-resistant seals, testing timekeeping performance and movement power consumption, cleaning the movement, and maintaining the exterior. Such maintenance services will effectively extend the service life of your mechanical watch.

　　Precautions for mechanical watch repair and maintenance

　　Do not open the case back of a mechanical watch casually, so as to prevent dust from entering the movement and affecting its normal operation. Do not place the watch in a wardrobe containing mothballs to avoid deteriorating the watch oil. Do not place the watch on power amplifiers, speakers, or televisions to avoid magnetization.

　　A mechanical watch stored for a long time without being worn should be wound regularly once a month, while an automatic mechanical watch should be gently swung back and forth for a few minutes or worn on the wrist for a period to wind automatically. This ensures that the components do not remain stationary for long periods, guaranteeing the running performance of the watch mechanism.

　　If an ordinary mechanical watch gets damp, dry cotton can be pressed onto the watch, and it can then be warmed with a 40-watt incandescent bulb for 5 minutes to completely evaporate all the moisture inside the watch.

　　When unpacking a mechanical watch, be sure to keep the packaging box used to protect the watch. These packaging boxes provide the safest protection for the watch, preventing it from being dropped or impacted.

　　Refurbishment of mechanical watch crystals. Once the crystal has been scratched with many lines, you can apply one or two drops of clean water onto the crystal, squeeze on a little toothpaste, and rub it to remove the scratches and make the crystal look like new. As long as you maintain the mechanical watch properly during daily wear, the watch can last for many years.

　　Precautions for daily mechanical watch maintenance

　　1. Do not use the watch in hot baths, saunas, or environments with significant temperature fluctuations (including water-resistant watches).

　　2. Do not operate the watch buttons or adjust the crown while underwater.

　　3. Please clean the bracelet and case regularly; for leather straps, avoid contact with water, moisture, and cosmetics, and keep them out of direct sunlight.

　　4. Please keep the watch away from magnetic fields; avoid prolonged proximity to electrical appliances, mobile phones, and magnets.

　　5. Do not disassemble the watch under any circumstances.

　　6. Please avoid subjecting the watch to impacts or drops.

　　7. Please do not adjust the watch date between 22 and 2 to avoid causing damage and inaccurate calendar jumps.

　　8. If the watch exhibits any abnormalities, it should be taken to a specialized watch shop for inspection immediately.
