THE WORLD’S LIGHTEST SPLIT-SECONDS TOURBILLON CHRONOGRAPH
Manual winding tourbillon movement with hours, minutes, split-seconds chronograph, 30-minute totaliser, and power-reserve, torque and function indicators.
Circa 70 hours (± 10%), without the chronograph running.
Actual power reserve results will depend on the period of time the chronograph is utilised.
ULTRALIGHT TOURBILLON CALIBRE IN TITANIUM AND CARBON TPT®
The Calibre weighs just 7 grams and fully deserves its qualifier ‘ultralight’. The secret to its feather weight lies in the use of grade 5 Titanium and Carbon TPT®, and in the extreme skeletonisation of components. Likewise, the density, stiffness and low thermal conductivity of titanium make it a material of choice in McLaren Racing’s Formula 1 engineering build programme.
NEW SPLIT-SECONDS SYSTEM
The Calibre introduces a latest-generation split-seconds mechanism developed by the Richard Mille engineers. Design of a new split-seconds mechanism and extensive research on the work of the split-seconds clamps have permitted a 50% reduction in the chronograph’s energy consumption, while at the same time reducing arbour friction.
The 6-column wheel that controls the various rockers for the split-seconds function was designed to guarantee flawlessly simultaneous movement, clean function lock, and highly stable settings.
In a manner similar to a car’s gearbox, the function indicator makes it possible to see the winding, neutral and hand-setting positions as the crown is pulled out. The active position is indicated via a hand at 4 o’clock pointing to the following functions: W (Winding) – N (Neutral) – H (Hands).
FAST-ROTATING BARREL (6 hours per revolution instead of 7.5 hours)
This type of barrel provides the following advantages:
The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance.
Provision of an excellent mainspring delta curve with an ideal power reserve/performance and regularity ratio.
WINDING-BARREL TEETH AND THIRD-WHEEL PINION WITH CENTRAL INVOLUTE PROFILE
The central involute profile of the winding-barrel teeth provides an optimal pressure angle of 20°, which promotes effective rotary motion and compensates for possible variations in the operation of the going train. This, in turn, ensures excellent torque transmission and a distinct improvement in performance.
