Introducing Richard Mille Unveils the New RM 75-01 Flying Tourbillon Sapphire

Richard Mille continues to blur the lines between horology and modern architecture with the new RM 75-01 Flying Tourbillon Sapphire. As its name suggests, the case is crafted entirely from sapphire crystal and draws inspiration from Gothic art.

Measuring 32.90mm in width and 46.75mm in height, the sculptural case required over 1,000 hours of machining and polishing, an impressive testament to the extreme technical demands of working with such a notoriously challenging material. The caseback, also fully made of sapphire in either lilac pink, sapphire blue, or clear sapphire offers a view of the movement and maintains a water resistance rating of 30 meters.

At first glance, the dial of the RM 75-01 resembles a mechanical landscape more than a traditional watch face with its skeletonized design. It’s framed by a red gold flange and accented with polished steel indices treated with Super-LumiNova, enhancing visibility in low light. The layout includes central hours and minutes, a function selector at 3 o’clock, and a skeletonized 72-hour power reserve indicator at 11 o’clock. The true centerpiece, however, is the flying tourbillon at 6 o’clock.

Powering the watch is the CRMT5 calibre, a manually wound movement that operates at 21,600 vibrations per hour (3 Hz). Built with Grade 5 titanium bridges and a PVD-coated baseplate, it delivers both robustness and lightness. Traditional hand-finishing techniques, such as polishing, sandblasting, and anglage, pay tribute to the craftsmanship behind the futuristic aesthetic. Even the gears are optimized with a pressure angle of 20° to improve torque transmission. Each watch is paired with a rubber strap, and pricing is available upon request.
