When the watch is accidentally scratched or cracked by the key, it can be used temporarily. However, for the watch with precise operation, the waterproof and dustproof performance of the watch will decline at this time, and it should be replaced in a professional watch shop as soon as possible. When there are scratches or slight scratches on the mirror surface of the watch, you can first drop one or two drops of water on the mirror surface of the watch, then squeeze a little toothpaste, and then wipe it back and forth with a cotton ball to remove the scratches and make the mirror surface as new.

As for serious damage, such as cracking, broken corners and serious damage, when the dial is full of debris, the following measures need to be taken immediately: the first thing to do is to stop the watch. Pull out the watch handle to stop the watch. Pulling out the watch handle can stop the watch and prevent the pointer from driving the glass to scratch the dial and calendar plate. Never set the hands and adjust the calendar quickly, and never try to take out the broken glass of the dial yourself. When sending the watch to the watch shop for maintenance, it is necessary to put the watch flat (preferably with the glass face down) in the box, and violent vibration and shaking are not allowed during maintenance. In the process of maintenance, tell the maintenance personnel not to let the glass fragments hurt the dial and hands.
