Designed for frequent travellers and others alike, this timepiece made a strong impression on the press 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 much as possible, notably by removing the need for a pusher in activating the time zone function.
The RM 63-02 World Timer repeats this exercise, incorporating the World Timer function at the heart of a brand new automatic in-house movement.
The rotating bezel in satin-brushed and polished grade-5 titanium is one of the masterpieces of the RM 63-02. Mounted on ball bearings for easy manipulation, it can be turned to select the desired time zone. When the name of the wearer’s current city is positioned at 12 o’clock, the RM 63-02 automatically defines the local time as well as the time in 23 other cities around the world thanks to its graduated 24-hour flange. This blue and white disk distinguishes nighttime and daytime hours, automatically incorporating the correction hour by hour. The bidirectional bezel interacts directly with the heart of the movement, and ensures the water-resistance of the case—crafted from vertically satin-brushed and polished grade-5 titanium—to 30 meters.
The movement’s designers selected the in-house CRMA3 caliber to drive the RM 63-02. It is assembled around an electroplasma-treated grade-5 titanium plate—the same material used for the majority of its bridges. The sculptural upper bridge is made from black-rhodium-plated, polished and circular-grained german silver, with round openings that provide glimpses of the going-train and World Timer mechanism in action. The RM 63- 02 caliber features an oversized date at 12 o’clock driven by two skeletonized disks, and a function selector which allows the user to navigate between the winding, time-setting or neutral positions with one simple push. Powered by a quick-rotation barrel that ensures the optimum regularity of the mainspring and a power reserve of 50 hours, it is wound by a rotor in 5N red gold and grade-5 titanium.
As part of our systematic quest to optimize the productivity and transmission of energy to the variable inertia balance wheel, all of the wheels in the CRMA3 caliber have an involute profile of 20°. The movement is enhanced by the hand-crafted finishes, which adorns the interior of the movement’s parts. Each piece of the movement requires many hours of work create anglage, drawn out edges, circular-graining and micro blasted bridges.
The RM 63-02 World Timer will be presented at the SIAR (Salón Internacional Alta Relojería), which takes place in Mexico City between October 20 and 22, 2015.
