Brand Watch Clean Factory is a professional organization dedicated to deep cleaning, maintenance, refurbishment, and repair of high-end watches. Its core is to use dust-free environment, precision equipment, and brand certified technicians to restore the appearance and movement performance of watches according to the original factory standards. It is commonly used in brand official after-sales or large luxury maintenance centers.
1、 Factory positioning and core capabilities
Service targets: Rolex, Patek Philippe, Audemars Piguet, Vacheron Constantin, Universal, Omega, Longines and other luxury/high-end brand watches in all categories.
Core value: Different from ordinary watch repair shops, it has the ability to disassemble and clean at the original factory level, polish at the micrometer level, adjust the movement, rebuild waterproofing, and replace parts. It can handle antique watches and complex function watches (tourbillon, perpetual calendar, three questions).
Typical scale: The professional factory covers thousands of square meters and is equipped with dust-free workshops, precision instrument rooms, polishing areas, and quality inspection areas; The team includes Swiss/brand certified senior technicians, watchmakers, and polishers, with core technicians requiring brand training and certification.
2、 Core service projects
- Deep cleaning of the movement (core)
Full disassembly: Non marking disassembly of needles, disassembly of dials, disassembly of the entire movement, and classification of parts into dedicated trays.
Precision cleaning: Ultrasonic cleaning machine+multi-stage specialized cleaning solution (oil removal, oxidation removal, rust removal), to remove micron level oil/dust; Hand washed key components (hairspring, gear teeth).
Inspection and replacement: Microscopic examination of gear wear, deformation of balance spring, and loss of shaft tip, and replacement of non-conforming original parts.
Accurate oiling: Inject multiple small amounts of oil (mainspring, wheel system, escapement) according to the original factory specifications to reduce friction and ensure precise timekeeping. - Cleaning and refurbishment of watch case/strap
Basic cleaning: Ultrasonic cleaning of the watch case, strap, and clasp to remove sweat stains, dirt, and oxide layers.
Polishing and wire drawing: Micron level polishing (mirror/satin/wire drawing), removing scratches and bumps, restoring the original factory texture; Precious metals (gold/platinum) require gold replenishment/laser welding to repair deep marks.
Waterproof reconstruction: Replace the waterproof rubber ring, sealing ring, and crown tube, conduct a dry/wet dual waterproof test (30-200 meters), and restore the original factory waterproof level. - Appearance and functional repair
Dial/pointer: Clean the dial, replenish glow in the dark, repair the pointer; Non marking disassembly and assembly to avoid damage to the dial/pointer.
Mirror replacement: Replace sapphire/mineral glass mirror and calibrate waterproof.
Complex function calibration: Testing and calibration of calendar, moon phase, timing, tourbillon and other functions to restore original factory accuracy. - Specialized services
Antique watch restoration: cleaning with ancient methods, replicating parts, restoring movements, and preserving historical value.
Customized maintenance: Regular maintenance according to the brand manual (mechanical watch 3-5 years/time, quartz watch 2-3 years/time).
Authenticity verification: Verification of movement/appearance/coding, and issuance of authoritative reports.
3、 Standard Operating Procedure (10 Steps)
Pre check reception: Verify the model, serial number, appearance/movement status, record any issues, and confirm the service plan.
Appearance protection: Apply protective film to prevent polishing/cleaning damage.
Full watch disassembly: Disassemble the strap → watch case → movement → dial/hands → disassembly of all movement components.
Movement cleaning: manual pre washing → ultrasonic multi liquid cleaning → drying → microscopic inspection.
Case/strap treatment: cleaning → polishing/drawing → gold plating/laser welding → drying.
Assembly and oiling of the movement: parts reassembly → precise oiling according to original factory standards → functional calibration.
Waterproof reconstruction: replace seals → watch case assembly → vacuum/pressure waterproof testing.
Travel time calibration: Six directional calibration, with daily error controlled within ± 5 seconds (mechanical meter).
Final inspection quality control: full inspection of appearance, travel time, waterproofing, and functionality, with high-definition archiving.
Delivery packaging: Clean appearance → Special packaging → Warranty card (usually 1 year) → Delivery.
4、 Key equipment and environment
Cleanroom: Class 10000/Class 1000 cleanliness, anti-static, temperature controlled, and humidity controlled, preventing the movement from being contaminated with dust.
Core equipment:
Ultrasonic cleaning machine: multi tank and multi liquid, suitable for different materials/dirt.
High magnification microscope: 100-200 times, detecting microscopic wear.
Travel time calibrator: imported from Switzerland, six directional calibration, accuracy of 0.1 seconds/day.
Waterproof tester: imported from Germany, dual testing of dry vacuum and wet pressure.
Polishing machine: Swiss precision polishing system with micrometer level removal capacity.
Laser welding machine: repair deep scratches, bumps, and restore the original factory appearance.
5、 Technician qualifications and technical standards
Qualification requirements: The core technician must have graduated from a Swiss watchmaking school or obtained official brand certification (such as Rolex or Patek Philippe certification), have at least 5 years of experience in the same brand, and be proficient in movement structure and original craftsmanship.
Technical standards: Strictly follow the Swiss watchmaking standard (ISO 3159) and the brand’s original manual, with 100% genuine parts, waterproof, timekeeping, and appearance all meeting factory standards.
6、 Key points for factory selection
Qualification certification: Priority brand official authorized after-sales or large luxury maintenance groups (such as Siku and Hengdeli), technicians need to have brand certification certificates.
Equipment environment: There must be a dust-free workshop and a complete set of Swiss/German imported equipment, and “roadside small shop” style workshops are rejected.
Transparent process: Supports full process visualization (monitoring/live streaming), allowing for viewing of the entire disassembly, cleaning, and assembly process.
Warranty commitment: Provide a warranty of at least 1 year, specifying the warranty scope (movement, waterproofing, polishing).
Price reference: Basic cleaning and maintenance (mechanical table) 500-2000 yuan; Deep maintenance (full disassembly+cleaning+oiling+waterproofing) 2000-5000 yuan; Complex function table/precious metal table priced between 5000-20000 yuan, based on brand, complexity, and material.
7、 Common Misconceptions
❌ Misconception 1: “Ultrasonic cleaning can damage the watch” – Professional factories use specialized cleaning solutions with precise parameters to only remove dirt without damaging the coating/parts; Only household cleaning machines used in ordinary stores can damage the watch.
❌ Misconception 2: “Mechanical watches do not need to be washed frequently” – they must be washed every 3-5 years, otherwise oil stains will deteriorate and dust will wear down the movement, resulting in inaccurate timekeeping and shortened lifespan.
❌ Misconception 3: “Polishing will thin the surface” – Professional polishing only removes micrometer level (0.01-0.05mm), and it will only become significantly thinner after normal maintenance for more than 10 times; Excessive polishing in ordinary stores will ruin the watch.
