Richard Mille RM 63-02 Automatic Worldtimer


the Richard Mille RM 63-02 Automatic Worldtimer revolutionizes the operation of the worldtimer complication by shifting time zone adjustment from a push-button or crown directly to a rotating bezel. The micro-blasted 5N red gold bezel features ball bearings and integrates a dedicated gear directly connected to the hour wheel within the movement. Rotating the bezel to position the current city at 12 o'clock instantly adjusts the local time, while simultaneously updating the remaining 23 cities displayed on the periphery. This interaction between case and movement eliminates the cumbersome operation of traditional systems.

A large, black rhodium-plated, circular-brushed bridge on the dial side reveals the worldtimer mechanism and frames the outsized date display at 12 o'clock. Two skeletonized titanium discs display the date, adjusted via a gold pusher at 11 o'clock. Richard Mille's signature function selector, located at 4 o'clock, features a visible titanium disc that cycles between neutral, winding, and hand-setting positions. World time is read on the inner edge of a scale marked in 24-hour increments, with a two-tone rose gold and burgundy disc distinguishing day and night. The 0.40 mm sapphire crystal dial, anti-reflective on both sides, virtually disappears, offering a clear view of the movement beneath.

The CRMA4 caliber, developed entirely in-house by Richard Mille, features a baseplate and bridges machined from grade 5 titanium, micro-blasted and electro-plasma treated to increase rigidity and ensure precise surface flatness. Measuring 33.50 mm in diameter and 7.73 mm thick, it oscillates at 28,800 vibrations per hour and is equipped with a free-sprung variable-inertia balance featuring four small weights on its beryllium copper balance wheel. This configuration eliminates hands entirely, improving chronometric stability. The fast-rotating barrel rotates once every five hours, rather than the usual 7.5, reducing periodic internal spring sticking. Furthermore, the 20° pressure angle of the involute tooth profile throughout the entire train compensates for deviations in hub centering due to temperature fluctuations and daily use. Hand-polished chamfered edges, micro-blasted recesses, filed edges, and a gray electroplasma treatment on the baseplate, combined with a Titalyt coating on the bridges, create a finish that reflects specific performance requirements rather than arbitrary decoration.

The Richard Mille RM 63-02 case, comprised of four parts and nearly 200 individual components, measures 47.00 x 13.85 mm and features a satin-finished 5N red gold bezel with polished bevels and a grade 5 titanium case middle. The bezel performs a dual function: adjusting the time zone while maintaining the integrity of the case, sealed with two nitrile rubber O-rings and ensuring water resistance to 30 meters. The bezel requires precision engineering, verified through 5,000 complete rotations. The case is assembled with twelve spline screws in grade 5 titanium. The sapphire crystal has a Vickers hardness of 1,800, is 1.10 mm thick at the center (increasing to 1.64 mm at the periphery), and is anti-glare treated on both sides. The case comprises three parts, containing a total of 106 components, 12 of which are dedicated to controlling the worldtimer bezel, while the remaining 86 Calibre CRMA4 components are directly used for the worldtimer function.

The RM 63-02 Automatic Worldtimer places the time zone adjustment function on the rotating bezel, transforming the action that typically requires a deliberate push of a button into a natural rotational motion, thereby resolving the fundamental contradiction between the convenience of a complication and the precision of mechanical engineering. The integration of the bezel into the movement, with a dedicated gear acting directly on the hour wheel, represents a true problem-solving approach rather than an incremental improvement. Limited to 100 pieces, the RM 63-02 in 5N red gold and titanium showcases Richard Mille’s ability to reinvent established complications through the art of materials science and engineering. The brand has created a world timepiece that prioritizes intuitive operation without sacrificing rigorous watchmaking, perfect for those who frequently travel between multiple time zones.
