Engineering Paradigms
Passive Shielding
Focuses on diverting magnetic flux lines away from the sensitive escapement using high-permeability Faraday cages.
- Utilization of soft iron (Mu-metal) internal housings.
- Industry compliance with ISO 764 anti-magnetic standards[cite: 2, 3].
- Historical benchmark for professional pilot and tool watches[cite: 2].
Intrinsic Immunity
Eliminates magnetic sensitivity at the molecular level by replacing ferrous components with non-paramagnetic alloys[cite: 2, 3].
- Implementation of Sycilium (Silicon) hairsprings and balance wheels[cite: 2, 3].
- Application of Nivagauss™ alloys to resist fields up to 1.5 Tesla[cite: 2, 3].
- Requirement for METAS Master Chronometer certification[cite: 2, 3].
Environmental Impact Standards
| Environmental Field | Gauss Rating | Mechanical Accuracy Impact |
|---|---|---|
| Daily Electronic Exposure | ~50 – 100 Gauss | Minimal to slight rate deviation (approx. +10s/day)[cite: 2, 3]. |
| Standard ISO 764 Field | ~60 Gauss (4,800 A/m) | Deviation must remain within ±30 seconds per day[cite: 2, 3]. |
| High-Tech Industrial Field | 15,000 Gauss (1.5T) | Zero deviation in Master Chronometer certified movements[cite: 2, 3]. |
Technical Maintenance FAQ
A sudden, persistent acceleration in the beat rate (often exceeding 30 seconds per day) is the primary symptom. A manual verification can be performed by placing the timepiece near a traditional magnetic compass; any needle deflection indicates residual magnetism[cite: 2].
Calibrated Turns Per Day (TPD) settings prevent excessive wear on the mainspring and slippage of the bridle. Our technical database indexes over 2,000 luxury models to ensure optimal winding tension for specific calibers.
Modern shielded winders provide a safe storage environment. However, for timepieces featuring “Intrinsic Immunity” (Silicon hairsprings), the ambient magnetic field of the winder motor poses no risk to chronometric precision[cite: 2, 3].
Silicon components are entirely non-paramagnetic and thermally stable, allowing for thinner case profiles and exhibition sapphire case backs without compromising magnetic resistance[cite: 2, 3].
