Overview
Titanium execution of the declutchable rotor automatic
The titanium RM 030, in the model’s tonneau case of 50.00 × 42.70 × 13.95 mm on a black strap. The case is tripartite, water resistant to 50 metres through two nitrile O-ring seals, and assembled with 20 grade 5 titanium spline screws and abrasion-resistant 316L stainless steel washers.
The calibre RMAR1 provides hours, minutes, seconds, date, a winding indicator and a power-reserve indicator, with the rotor declutching at 50 hours of reserve and re-engaging at 40.

Design and engineering
- Declutchable rotorThe mechanism combines automatic clutching and declutching of the winding system with a torque sensor, so the spring is held at an ideal tension.
- Winding indicatorAt 12 o’clock; the power-reserve scale sits at 9 o’clock and the date at 7.
- Free-sprung balance with variable inertiaGlucydur®, four arms, moment of inertia 4.8 mg·cm², lift angle 53°.
- Titalyt®-treated titanium movementWet-sandblasted grade 5 titanium with a Titalyt® treatment.
- Case machining86 preparatory operations, 49 of them striking, before cutting and milling.
