Mercier & Fils Technologies
Your caliber deserves its own settings. Mercier & Fils combines winding precision, watch support and access control in a range spanning two-watch Mazarin and Rivoli winders to sixty-slot Régent safes.
Coil Winding®: precision you can measure
650 TPD programmed. 646.7 turns per day measured over seven days: a −0.51% deviation. Coil Winding® gives each watch its own winding program, with independent turns-per-day and rotation-direction settings.
7-day continuous test
23.4 dBA with 12 modules
At the watch position
These reference results were recorded on the Rivoli 12. Our tests cover the entire Mercier & Fils range, which shares the same motor and integration design; observed results are very similar. View the method and readings.
Rolex, Patek Philippe, Audemars Piguet, Omega: compatible with your caliber
650–2,200 TPD. Clockwise, counterclockwise or alternating rotation. An independent program for every watch. A Rolex and a Patek can share the same Mercier winder while retaining different settings.
| Caliber | Program | Mercier compatibility |
|---|---|---|
| Rolex 3235 · Datejust / Submariner Date | 650 TPD · BOTH | Yes — alternating rotation |
| Rolex 3230 · No-date Submariner | 650 TPD · BOTH | Yes — alternating rotation |
| Patek Philippe 26-330 S C | 800 TPD · CCW | Yes — counterclockwise rotation |
| Audemars Piguet 2385 · Royal Oak Chronograph | 800 TPD · CW | Yes — clockwise rotation |
| Omega 8800 · Seamaster | 650 TPD · BOTH | Yes — alternating rotation |
The Rolex Perpetual rotor, the unidirectional winding of the Patek Philippe 26-330 and the bidirectional winding of the Omega 8800 illustrate different architectures. Coil Winding® applies the turns-per-day and direction settings specified for the caliber concerned.
Our database brings together over 5,800 watch references, 86 brands and more than 200 caliber and variant designations. Find your exact watch reference, then set its module.
Find my watch settingsTechnical sources and compatibility
The TPD and direction settings in this table are recommendations from our Mercier & Fils TPD guide. Manufacturer documentation describes the movements: Rolex 3235 and Perpetual rotor, Patek Philippe 26-330, Omega 8800, Audemars Piguet 2385. These manufacturer sources are not presented as official TPD recommendations. Compatibility means the ability to apply the winding program; it does not imply affiliation with or endorsement by the named manufacturers.
Seven days of measurement. Results you can inspect.
Internal Mercier & Fils test on Rivoli 12, 650 TPD / BOTH, over seven continuous days, at an ambient temperature of 22.3 °C.
| Day | Measured turns |
|---|---|
| 1 | 648 |
| 2 | 646 |
| 3 | 647 |
| 4 | 645 |
| 5 | 650 |
| 6 | 644 |
| 7 | 647 |
| Average | 646.7 turns/day |
Total: 4,527 turns. Deviation calculated from the unrounded average: −0.51% relative to 650 TPD. Daily counts range from 644 to 650 turns.
Sound: one module and twelve modules running
At 30 cm, measured levels are 20.1 dBA LAeq with one active module and 23.4 dBA LAeq with all twelve modules active. Background noise before the test was 18.6 dBA. These readings include background noise; they are not background-corrected source-only values.
Magnetic field: a +1.3 µT variation
At the watch position, the measured field rises from 47.8 µT with the device switched off to 49.1 µT during operation, an observed difference of +1.3 µT.
Instruments and measurement context
- Sound: NTi Audio XL3 with M2914 microphone.
- Magnetic field: Metrolab TFM1186.
- Actual rotations: Keyence LR-Z sensor with NI USB-6001 acquisition.
- Temperature and humidity: Testo 440 with 0636 9771 probe.
- Power consumption: Rohde & Schwarz HMC8015, part of our test equipment; no consumption result is published here.
- Positioning: micrometric support / tripod.
LAeq describes an A-weighted equivalent sound level. The twelve-module configuration is that of the tested Rivoli 12. The 22.3 °C reading describes ambient temperature, not internal temperature rise. The 1.3 µT difference compares two total-field readings; it is not an antimagnetic certification of a watch. These are internal test results, separate from independent certification.
Flex Mount®: support that adapts to your watch
The telescopic Flex Mount® cushion adjusts the holder to the bracelet. Metal, leather or rubber: the watch receives tailored support, with a stated capacity for cases up to 55 mm. Adjusting the holder complements the motor settings for stable rotation.
BioLock®: your collection at your fingertips
BioLock® provides fingerprint access on equipped models. Biometric access simplifies everyday use and authorized shared access. For Régent safes, the protection level and lock depend on the selected configuration.
From 2 to 60 watches. One commitment to quality.
Mazarin and Rivoli winders and Régent safes cover collections of 2 to 60 watches. The range complies with CE and RoHS requirements. Our quality management system is ISO 9001 certified.
