Richard Mille - RM 30-01 Automatic with Declutchable Rotor (blog)
2023-09-04
Richard Mille is launching the new RM 30-01 Automatic with Declutchable Rotor, a timepiece that benefits from the aesthetic solutions and technical advances that are adopted with each new design and focuses on ease of use despite its great mechanical complexity.info: xtime-store
The sculptural 42.00 x 49.94 x 17.59 mm tonneau-shaped case is presented in two variations: one featuring a case back and bezel in 5N red gold teamed with a case middle in grade 5 titanium, while the other is entirely machined in this hypoallergenic material, which boasts exceptional resistance to corrosion and shocks. info: xtime-store
Its weight, which has been reduced as much as possible (96 grammes including the strap), and its ergonomics contribute to exceptional comfort on the wrist. info: xtime-store
Both versions are enhanced by flawless finishes with satin-brushed surfaces and polished bevels. The tripartite case is water resistant to 50 metres / 165 feet, ensured by 2 Nitrile O-ring seals. The case is assembled with 20 spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.info: xtime-store
Combining titanium and sapphire, the double dial boasts a reinterpreted skeletonised design that helps to establish graphic balance. The grade 5 titanium bridges and baseplate create perspective and depth through the multiplication of their parallel segments. The 1.50 mm thick sapphire crystal features an anti-glare treatment on both sides.info: xtime-store
Semi-instantaneous, the oversized-date display is placed in a horizontal aperture at 4 o’clock.info: xtime-store
The function-selector, clutch engagement and power-reserve indicators are arranged in a completely new way, highlighted by coloured transfers for added emphasis.
The function selector is very easy to use. In a manner similar to a car’s gearbox, a push-button located at 2 o’clock allows one to select the hand-setting, date-setting and winding functions with a simple push. The indicator positioned on the dial above the oversized date informs them of the chosen option at all times: W for winding, D for date correction, and H for setting the hands.info: xtime-store
To remove any tension linked to winding, the RM 30-01’s variable-geometry rotor automatically declutches once the power reserve reaches 55 hours by disconnecting itself from the winding mechanism.info: xtime-store
It thus enables the 4Hz (28,800 vibrations per hour) RMAR2 calibre to operate when the barrel torque benefits from the best constant torque/power ratio. When energy starts running short as soon as the 40-hour power-reserve threshold is crossed, the rotor reengages to rewind the barrel spring. It also allows the oscillating organ to operate while delivering excellent chronometric performance.
It is possible to observe these phases on the clutch engagement indicator located at 11 o’clock, which shows the wearer whether the rotor is operating in the winding phase (on) or is disengaged (off).info: xtime-store
The price of the Richard Mille RM 30-01 Automatic with Declutchable Rotor RM 30-01 is CHF 185,000 for the titanium edition and CHF 225,000 for the rose gold and titanium version. Both prices are excluding sales taxes). info: xtime-store
