There's something fundamentally appealing about a world-timer complication. Richard Mille unveiled their first Worldtimer complication paired with a tourbillon as far back as 2013. The RM 58-01 Tourbillon World Timer was designed for frequent travelers and others alike. This timepiece made a strong impression thanks to its remarkably easy-to-use multi-time-zone mechanism. When designing the RM 58-01, Richard Mille’s goal was to simplify the setting of this complication as far as possible, notably by removing the pusher. Then in 2014, Richard Mille unveiled the first iteration of the RM 63-02 Automatic World Timer at the SIAR in Mexico City, fully cased in titanium.
Things to Know About the Watch
Now comes the RM 63-02 Automatic Worldtimer in 5N Red Gold and Titanium in a 100-piece limited edition that repositions this classic complication for the modern collector who values both innovation and intuitive functionality. What immediately distinguishes the new Richard Mille RM 63-02 is its bezel-integrated time zone adjustment system.
Rather than fiddling with pushers or pulling out the crown, travelers rotate the micro-blasted 5N red gold bezel—mounted on ball bearings for smooth operation—to select their destination city and adjust the date with the pusher at 10 o’clock. A dedicated wheel connects the bezel directly to the hour wheel, instantly adjusting local time while simultaneously updating all 24 time zones displayed around the dial.
It's an elegantly simple solution that required complex engineering. The bezel mechanism alone comprises 12 dedicated components in the case, working in concert with 86 additional parts within the Calibre CRMA4 movement. Richard Mille tested the function through 5,000 complete rotations, verifying water resistance every 1,000 cycles to ensure the complication's durability matches its ingenuity. The pusher at 4 o’clock allows one to select the neutral, winding, and hand-setting functions of the crown. An aperture at 4 o’clock indicates the selected function: N (Neutral), W (Winding), or H (Hand Setting)—the indication on previous models was less visible.
The 47 mm round case presents an interesting departure from Richard Mille's typical barrel-shaped aesthetic, executed in a two-tone combination of satin-finished 5N red gold and grade 5 titanium. At 13.85 mm thick, it maintains remarkable wearability despite housing a substantial automatic movement with world-timer complications.
A two-tone rose and burgundy disc elegantly distinguishes day from night across all time zones, while the graduated 24-hour inner flange ensures instant readability. The sapphire dial and crystals receive anti-glare treatment, and the entire package offers 30 meters of water resistance—ample for daily wear. The date aperture sits discreetly under the 12 o’clock numeral.
The Movement
The in-house CRMA4 caliber exemplifies Richard Mille's commitment to advanced materials and innovative construction. Grade 5 titanium is used for both baseplates and bridges, treated with an electroplasma coating for enhanced rigidity. The skeletonized architecture reveals the world-timer mechanism beneath a black rhodium-plated bridge, creating visual depth while maintaining legibility.
Details matter here: a fast-rotating barrel—5 hours per revolution versus the traditional 7.5—reduces mainspring adhesion and delivers 50 hours of power reserve. The free-sprung balance with variable inertia ensures superior chronometric performance and shock resistance. Even the gear teeth receive special attention, employing a 20-degree pressure angle profile that optimizes torque transmission throughout the going train.
Summary & Price
The Richard Mille RM 63-02 Automatic Worldtimer takes a beloved horological function and makes it genuinely easier to use, wrapping that innovation in materials and finishing that justify the Richard Mille name. For the frequent traveler who appreciates mechanical ingenuity, this worldtimer presents a compelling proposition—complexity made invisible through intelligent design.
