A professional factory/center specializing in the Clean Factory and maintenance of mechanical/quartz watches in China, with a 100 level dust-free workshop, fully automatic washing machine, and Swiss standard process as the core, covering the entire process of deep cleaning, appearance refurbishment, and waterproof testing of the movement. The following are mainstream authoritative institutions and core services:
Professional cleaning factory core services and processes (universal for mechanical/quartz watches)
Standard process (factory level)
Initial inspection: waterproof, travel time, appearance inspection, issue report
Completely disassembled: case, strap, movement, dial, and hands separated
Cleaning: The movement is cleaned using a German Elma fully automatic watch washing machine (with multiple slots of ultrasonic waves and specialized cleaning solution), and the case/strap is manually cleaned with ultrasonic waves
Drying/Inspection: Dry in a dust-free environment, check for wear/corrosion
Lubrication/Assembly: Swiss Moebius oil for mechanical watches, cleaning circuit contacts for quartz watches
Calibration: Witschi calibrator calibration accuracy
Waterproof test: Air pressure/water pressure test (10-1000 meter level)
Re inspection: Secondary confirmation of travel time, appearance, and waterproofing
Cleaning classification (by depth)
Basic cleaning: Ultrasonic cleaning of watch case/strap, wiping of watch mirror, dust removal of gaps (daily maintenance)
Deep cleaning (mandatory maintenance):
Mechanical watch: fully disassembled core → ultrasonic+manual precision washing → drying → Moebius original oil lubrication → assembly → calibration → waterproof testing
Quartz watch: movement disassembly and cleaning → circuit/coil cleaning → battery compartment rust removal → waterproof ring replacement → time calibration
Appearance cleaning/refurbishment: polishing of case/strap (brushed/mirrored), cleaning of scale/pointer, repair of scratches on watch mask
