Cleaning and lubricating the movement of a watch, referred to as "oil washing", is a routine and very important work in watch maintenance. The purpose of oil washing is to adhere to the cleanliness of watch parts and the necessary lubrication of machine parts, so as to ensure the accuracy of watch parts, improve the travel accuracy of watch machines and prolong the service life of watch machines. Under normal circumstances, the instrument is generally washed once after two years of use. Under normal circumstances, oil washing is often carried out while adjusting and repairing parts. In addition, while checking the instrument failure, when the following problems are found, the instrument must also be washed with oil:

A. The lubricating oil in the movement is dry or sticky. This will increase the resistance of the movement of the parts and make the watch machine inaccurate.

B.there is too much lubricating oil in the instrument. This will cause oil to overflow everywhere and pollute parts, especially the escapement speed regulating mechanism, thus making the meter stop or obviously inaccurate.

C. Foreign objects enter the movement, such as dust particles, metal particles and fine fibers. This will cause the transmission mechanism of the watch machine to be blocked, making the watch machine unable to walk or even stop.

D, parts rust.

If there is anything wrong with your watch, you can take it to Guangcheng Watch Shop, Room 602, Block B, Yi Yin Global Center, No.42 Yaohang Street, Haishu District, Ningbo, and ask the master to check and repair it for you.
