Overview
Red gold execution of the declutchable rotor automatic
This RM 030 carries an 18k red gold case in the model’s tonneau of 50.00 × 42.70 × 13.95 mm, on a black rubber strap.
The calibre RMAR1 is a skeletonised automatic movement with 40 jewels running at 4 Hz. Its rotor declutches from the winding barrel when the power reserve reaches 50 hours and re-engages at 40, so the mainspring is never held at full tension and torque delivery stays in its best range.
Key details
Design and engineering
- Declutchable rotorFour years of development went into the concept, which links automatic clutching and declutching of the winding system to a torque sensor.
- Winding indicatorAt 12 o’clock, reading on when the rotor is winding the barrel and off when it is disengaged.
- Titalyt®-treated titanium movementBaseplate, bridges and balance-cock in grade 5 titanium, wet sandblasted and Titalyt® treated; barrel bridges PVD coated.
- Movement mountingNo casing ring; the movement is carried on chassis mounting rubbers fixed by four grade 5 titanium screws.
- Case assembly20 grade 5 titanium spline screws with abrasion-resistant 316L stainless steel washers, two nitrile O-ring seals for 50 metres.
