The Richard Mille RM 67‑01 is the brand’s first ultra-thin tonneau-shaped automatic watch, combining elegant design with technical excellence. Its titanium case measures just 7.75 mm thick and 38.7 × 47.5 mm in size, crafted through over 200 precise machining steps.
Inside, the skeletonised CRMA6 calibre is only 3.6 mm thick and features a free-sprung balance, platinum rotor, and 50-hour power reserve. Functions include hours, minutes, date at 5 o’clock, and a function selector at 2 o’clock. The open-worked dial with Arabic numerals and sapphire crystal front and back highlights its mechanical beauty.
A marine-style watch with a self-winding mechanism and a date display. Equipped with a balance spring, lever and escape wheel made of silicone. It has a sapphire case back and is water resistant to 5 bar (50 m). The diameter of the watch is 33.8 mm.
Available in a steel version with a frame set with 50 diamonds weighing 1.16 ct. The dial is available in blue or silver-plated, decorated with 8 diamonds weighing 0.09 ct. It has a gold oscillating mass, hand-engraved on the rose-shaped engine, and a steel bracelet.
With slightly reduced dimensions but still retaining the iconic wide dial opening of the TONDA PF Micro-Rotor, the TONDA PF Automatic 36 mm is perfectly suited for those with slender wrists or for those who prefer the current trend of slightly smaller vintage-style timepieces.
