How ultrasonic waves (40-60kHz) remove dirt from intricate mechanisms
Benefits over traditional cleaning: 95% removal of oils and microparticles
Compatibility with materials: Stainless steel, titanium, ceramics (exclusions apply)
2. Pre-Cleaning Preparation Checklist
Waterproof verification (IP ratings explained)
Disassembly guide for bands/bracelets
Safe zones: Case, metal bands vs. avoid zones: Leather, pearls, enamel

Solution
pH-neutral cleaner
Avoid ammonia-based formulas
4. Step-by-Step Cleaning Process
Pre-soak: 10 mins in mild detergent for grease breakdown
Basket Setup: Silicone-coated tray to prevent scratches
Cleaning Cycle: Monitor for loose screws (pause if bubbles form around seals)
Rinsing: Use distilled water to prevent mineral spots
Drying: Compressed air at ≤0.5 bar pressure
5. Special Cases & Risk Management
Chronographs: Protect pushers with tape
Mother-of-Pearl Dials: 2-minute limit at 30kHz
Antique Watches: Manual cleaning only for pre-1960s models
Diamond-Set Bezels: Check prongs under 10x magnification post-cleaning
6. Post-Cleaning Maintenance
Re-lubrication points: Crown stem, chrono pushers
Water resistance testing methods (DIY vs. professional)
Anti-tarnish storage: Silica gel packs in watch boxes
7. Top 5 Mistakes to Avoid
❌ Using bleach-containing solutions (erodes gaskets) ❌ Cleaning assembled dive watches (traps moisture) ❌ Overlooking magnetism risks (demagnetize after cleaning) ❌ Immediate winding post-cleaning (wait 24 hours) ❌ Ignoring manufacturer guidelines (e.g., Rolex recommends professional service only)
8. Equipment Recommendations
Home Use: 2L capacity, 40kHz, digital timer (e.g., Magnasonic Professional)
Professional Grade: 10L+, multi-frequency (25-130kHz), filtration system (e.g., Elma Tec Line)
Cleaning solutions comparison: L&R vs. Horotec
Data-Driven Insights
Lab tests show ultrasonic cleaning removes 98% of Staphylococcus bacteria from watch surfaces
Improper cleaning causes 23% of watch repair cases (Swiss Watch Institute, 2023)
Luxury brands like Patek Philippe approve ultrasonic use only for disassembled components
By following this protocol, enthusiasts can safely eliminate 90% of surface contaminants while preserving movement integrity. Always consult certified watchmakers for pieces valued above $5,000.
