Richard Mille RM 63-02 Automatic Worldtimer

Complication Made Invisible
The RM 63-02 Automatic Worldtimer celebrates travel in horological form, incorporating a technical complication that transcends time and place in the elegant and distinctive Richard Mille style. An ingenious time zone setting mechanism allows the wearer to instantly read the local time anywhere, making this new watch a valuable companion for frequent travelers.

A Quest for Simplicity

The RM 63-02's most striking feature is its reinterpretation of the worldtimer complication. Unlike traditional watches, which use a crown or pushers to adjust the time, Richard Mille's movement and case engineers worked together to place this function directly on the rotating bezel.

CRMA4 Caliber
Automatic movement with hours and minutes, an oversized date, and a 24-hour universal time display.

Grade 5 Titanium Baseplate and Bridges
Micro-blasting of grade 5 titanium treated with electroplasma imparts exceptional rigidity to the entire assembly, along with the precise surface flatness required for flawless operation of the gear train.

The skeletonized baseplate and bridges undergo rigorous and comprehensive testing to optimize their durability.

Thanks to the micro-blasted 5N red gold bezel, equipped with ball bearings, travelers can select a city and instantly advance to the desired time zone with a simple turn. A gear integrated into the bezel, connected to the hour wheel, simultaneously adjusts the local time of the city at 12 o'clock and updates the times of the other 23 cities on the bezel. A 24-hour graduated ring within the bezel makes it easy to read the time at any given moment. The two-tone rose gold and burgundy dial distinguishes day from night and automatically adjusts for each time zone.

Function Selector

A pusher at 4 o'clock selects neutral, winding, and manual setting with a simple press, similar to a car's gearbox. An aperture at 4 o'clock displays the selected function: N (Neutral) - W (Winding) - H (Hand-Setting).

Gear Teeth

The watch's entire going train, the primary mechanism transmitting power to the movement, features a special tooth profile. The teeth have a 20° pressure angle. This system compensates for any differences that may arise between the centers of individual teeth, such as those caused by temperature fluctuations and normal use, and facilitates optimal transmission of torque to the balance, ensuring exceptional chronometric precision.

Case

The RM 63-02 features a round case measuring 47 x 13.45 mm, crafted from satin-finished 5N red gold with polished chamfers and a grade 5 titanium caseband whose finish mirrors the front. The case's contours are designed for ease of use and all-day wearing comfort, particularly thanks to the multi-radius milling process on the caseback, a hallmark of the brand. The three-part case comprises 106 components, 12 of which are dedicated entirely to controlling the world time bezel. A further 86 parts of the Caliber CRMA4 contribute to this function.

This innovative design requires extreme precision in all components to ensure the optimal and long-lasting operation of this complication. Its reliability is verified by testing it through over 5,000 complete rotations, including checking the case seals every 1,000 rotations to ensure water resistance to a depth of 30 meters.
