Generally speaking, there are several reasons for dust on the dial of a watch: First, the dust entering during use is not well sealed, usually it is either dust or water; The second is the dust that enters before leaving the factory. The dust on the dial is not from the outside, but caused by internal wear.
Dust enters the watch dial, usually due to gradual infiltration during long-term wear. If only fine dust enters, it does not need to be cleaned without affecting the appearance and use. However, if a certain length of dust such as hair or acrylic fiber enters the watch dial, it needs to be noticed, because such dust is likely to cause the movement to run. In this way, you have to go to a professional maintenance point for cleaning immediately, and you should also consider the problem of resealing after cleaning. Need to have an agreement with the maintenance point, otherwise, in order to clean the watch, the waterproof and dustproof function of the watch is worthless.
You can take your watch to Room 2 1 Floor 2 109, North Tower, Suning Plaza, Wuxi Renmin Middle Road109, and ask the master to take a look at it for you.
