Why do Longines watch hands fall off? What should I do if the watch pointer drops?

1, it is common for the hands to drop. When the watch is hit hard, it may cause the hands to fall off. If the hands of the watch drop, it is recommended to stop the watch immediately to avoid scratching the dial when the watch moves. 2. Watch hands fall off: When the watch shakes violently, the hands may fall off, especially the second hand. If the second hand (including a small second hand or a pointer with other functions) has dropped, it may get stuck between the hour hand, the minute hand and the dial, so if the watch continues to move, the second hand will be moved and scratched on the dial, resulting in scratches on the dial. Of course, if you have to dial the needle at this time, the situation will be even worse. You know, the dial is of high value, and some accessories are not easy to find.

1, the gap between the hour hand and the dial becomes smaller: the distance between the hour hand and the dial is the shortest. If there is no safety gap, it will rub against the dial, causing arc scratches on the dial, including the night light on the hour hand, and the night light powder will also be rubbed off. In addition, when the position of the hour hand is too low, it rubs on the logo of the dial, and when the position of the minute hand is too low or the distribution shaft is skewed, the front end of the minute hand rubs on the time symbol of the dial. This will not only cause scratches, but also bring faults to the watch when walking.

3. Blue steel hands rust: Although blue steel hands are high-grade and beautiful, they rust easily when they are wet. When the rust grows down, it will rub the dial and cause arc scratches on the dial. This rust is still difficult to wipe off when it is repaired. The rust component should be called "iron oxide". In ancient times, the ancients used it to draw caves and rock walls, which can be preserved for thousands of years.

Luminous hands are also harmful to the dial: especially old watches, because at that time, luminous materials were all promethium, which was a radioactive element, which was not good for people's health; Now the luminous materials of watches are all tritium, which is very safe. Watches that are not used for a long time, such as collectibles, need special attention. If the hour hand and the minute hand are always fixed in the same position, the night light on the pointer will do harm to the dial. If cymbals are used as the night light material, the color of the dial may be changed, mainly the silver ray dial, but other types or colors may not, and the color change position just corresponds to the position of the pointer.

4. If you find that the hands of the watch move or fall off, you must stop the watch immediately. If there is no second stop device, pull out the watch handle and let the watch stop gradually. Never set hands and wind up at this time! You can put the watch glass down and send it to the watch after-sales maintenance center for repair in time.

In case the watch shakes violently, you should also carefully observe the hands, especially whether the distance between the hour hand and the dial has changed. When the blue steel pointer is found to be rusty, it should also be repaired in time.
