Professional watch Clean Factory and maintenance services primarily fall into two categories: exterior cleaning and maintenance, and deep cleaning and maintenance of the movement. The service processes vary slightly for watches with different price points and functions (quartz watches/mechanical watches, waterproof watches/non-waterproof watches), as follows: Exterior cleaning and maintenance (basic items, applicable to all watches) Dismantling components: First, remove the strap and clasp, and separate the case from the crystal (if the crystal is detachable).
Targeted cleaning of metal straps/cases: Use a soft-bristled brush with a neutral detergent to scrub away dust and sweat stains from the crevices. For stubborn stains, use an ultrasonic cleaner for oscillating cleaning. Afterwards, rinse with clean water, dry, and finally polish and buff (to remove fine scratches).
Leather strap: Wipe with a dedicated leather cleaner, avoid getting it wet, and apply leather care oil after cleaning to prevent drying and aging.
Rubber/silicone watchband: Simply scrub with a cleaning agent and wipe dry.
Inspection and replacement: Inspect the watch glass, bezel, and crown for any signs of looseness or damage, and check the waterproof gasket for any signs of aging. If any issues are found, replacement will be recommended.
Deep cleaning and maintenance of the movement (core project, mainly applicable to mechanical watches) After long-term use, the lubricating oil in the movement of a mechanical watch will dry up and generate oil sludge, leading to inaccurate timekeeping. This is the core purpose of deep maintenance, and the process is relatively complex: complete disassembly: professional technicians will disassemble hundreds of components (gears, springs, balance wheels, etc.) of the movement one by one and place them in categories.
Cleaning components: Use a dedicated cleaning solution (divided into initial cleaning and fine cleaning) or an ultrasonic cleaning machine to remove oil sludge, dust, and dried lubricating oil from the components. Afterwards, use a professional reagent to dry them to avoid rust caused by residual moisture.
Reassembly and lubrication: According to the original factory standards of the movement, reset the components one by one, and precisely apply specialized lubricating oil to key areas such as gear meshing points and bearings to ensure smooth operation.
Debugging and calibration: After assembly, use a watch calibrator to test the accuracy of the watch’s timekeeping (including parameters such as daily variation, amplitude, and bias). Based on the test results, adjust components such as the balance wheel and hairspring until the error standards are met.
Waterproof test: For waterproof watches, professional waterproof tests (such as pressure water testing) will be conducted after maintenance to ensure that the waterproof performance meets the standards.
Service precautions Service cycle: For quartz watches, basic appearance maintenance is generally sufficient every 2-3 years; for mechanical watches, it is recommended to undergo deep cleaning and maintenance of the movement every 3-5 years.
Price difference: Basic appearance cleaning and maintenance are relatively inexpensive, ranging from tens to hundreds of yuan; deep maintenance of mechanical watch movements is more expensive, with prices varying from hundreds to thousands or even tens of thousands of yuan, depending on the watch brand (general brand / luxury brand) and the complexity of the movement.
Selection of channel: It is recommended to choose official after-sales service of the brand or a formal watch repair and maintenance institution to avoid damage to the movement or affecting the waterproof performance due to non-professional operation.
