The professional Clean Factory for high-end watches is not ordinary cleaning, but a standardized process of fully disassembling, ultra precision cleaning, re lubrication and calibration of the movement, case and strap in a dust-free and constant temperature environment. It is usually completed by the brand’s official service center or third-party factories with international qualifications. The following are the mainstream professional high-end watch cleaning/maintenance factories and service centers in China:
