RM 012 TOURBILLON 512.45PR.91

TECHNICAL SPECIFICATIONS OF THE RICHARD MILLE TOURBILLON RM 012 (Platinum) LIMITED EDITION 30 PIECES

This Richard Mille tourbillon wristwatch has been created in a limited edition of 30 numbered examples in platinum. With dramatic lines inspired by architecturally engineered structural forms, the tubular, angled configuration of the 012 offers optimal stiffness and torsial rigidity with exceptional resistance to thermal change and corrosive elements. It is unique in the manner in which it unites the functions of the watch’s baseplate with those of the movement and bridges into a technically coherent and visually inseparable totality.

CALIBER RM 012: Manual winding tourbillon with hours and minutes.

Dimensions: 48 mm x 39.30 mm (widest point) x 13.84 mm (thickest area)

MAIN FEATURES
(MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)

ALUMINIUM ALLOY WINDING BARREL, GOING TRAIN AND TOURBILLON CAGE
The aluminum alloy Anticorodal 100 (AlMgSi1) is normally used in industrial engineering applications such as skyscrapers, ships and sports cars and is composed of aluminum, magnesium and silicium. This particular alloy was selected for its combined qualities of low mass inertia, endurance and dynamic strength, the special ability to absorb vibrations and a high resistance to corrosion and wear.

COMBINED TUBE AND BRIDGE STRUCTURES IN STEEL PHYNOX ALLOY AND TITANIUM
SPLINE SCREWS IN GRADE 5 TITANIUM
TEETH OF BARREL AND THIRD WHEEL PINION WITH CORRECTED INVOLUTE PROFILE
The corrected profiles of the teeth allows a double pressure angle of 10° and 20°, thus effectively promoting smooth movement and compensating possible variations of gear engagement. This ensures excellent torque transmission and a distinct improvement in performance.

BALANCE SPRING
Developed in the 18th century, perfected and codified in the 19th, the specially calculated curvature of the balance spring provides excellent chronometric results in tourbillon escapements.

VARIABLE INERTIA, FREE SPRUNG BALANCE
The free-sprung balance gives better reliability in the event of shocks, allows for efficient movement assembly and disassembly, and also guarantees better chronometric results over an extended period of time.

CROWN
In grade 5 micro-blasted titanium, with double seal O-ring and collar in Alcryn.
