WORLD TIMER AUTOMATIC WATCH

Richard Mille’s RM 63-02 WORLD TIMER AUTOMATIC WATCH
Richard Mille first unveiled the RM 58-01 Tourbillon World Timer at the 2013 Salon International de la Haute Horlogerie.
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 far as possible, notably by removing the pusher.
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 nickel silver, whose round openings provide glimpses of the dial-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 adorn almost every component. Each piece of the movement requires many hours of work to polish angles, draw out edges, circular-grain gear trains and microblast 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.
