TOURBILLON PHOENIX - MICHELLE YEOH

Scroll down

AN EXERCISE IN STYLE

Richard Mille invented a new vocabulary of form on a mythological theme in close collaboration with Michelle Yeoh. The challenge was that in order to keep faith with aesthetic principles, no element could be reduced to a purely decorative role.

Main characteristics

All the shapes that create the three dimensional effect of the Phoenix, a symbol of beauty and perpetual renewal, have a technical function in the mechanisms of the watch. Available in 18K white gold, red gold and titanium gem-set case.

Limited edition of 18 unique pieces.

01
CALIBER RM 051
Manual winding tourbillon movement with hours, minutes and power reserve, inspired by the RM 026.

BLACK ONYX BASEPLATE Onyx is a variety of cryptocrystalline quartz chalcedony composed of silicium dioxide, (SiO2). The rectilinear black and white parallel stripes version is part of the agate types. The fully black type is called Black Onyx, and is said to be able to deflect harmful energy down to the earth, while providing stability. Considered as a charm-stone against spells, Black Onyx also symbolizes equilibrium and inspiration.

02
CALIBER RM 051
Manual winding tourbillon movement with hours, minutes and power reserve, inspired by the RM 026.

BRIDGES MADE OF TITANIUM These components are in grade 5 titanium with black PVD treatment. This provides the whole assembly great rigidity, as well as precise surface flatness which is essential for the perfect functioning of the gear train.

03
CALIBER RM 051
Manual winding tourbillon movement with hours, minutes and power reserve, inspired by the RM 026.

POWER RESERVE Circa 48 hours. This function is displayed using a newly designed differential power reserve system with a printed red line on a moving disc located between 10 and 11 o’clock.

CASE RM51

In the world of horology, the case of Richard Mille watches is currently considered as the most difficult to manufacture. This tripartite tonneau-shaped case is fully curved, which enables the watch to be ergonomic and comfortable but is time consuming during its production and requires a high level of quality control. These front and back curves are part of the Richard Mille watch case regardless of their shapes (tonneau, round, rectangular). They demand ultimate precision and no stress in the metal. The bezel side and the case back have to be perfectly assembled in the case middle with no constraints, to prevent the sapphires from any damage. These manufacturing specifications required one year of research and development. The tonneau shape of the RM 051 requires 47 stamping operations including 21 for the forming. Tooling takes 4 hours and the RM 051 is obtained after 255 milling operations. The finishing process requires a full day for grinding, glazing and polishing. The tripartite case is water resistant to 50 meters, ensured by two Nitril O-ring seals. The case is assembled with 12 spline screws in grade 5 titanium and abrasion resistant washers in 316L stainless steel.

BARREL PAWL WITH PROGRESSIVE RECOIL RM51

This device permits a profitable winding gain (circa 20 %), especially during the winding start, when the spring is not charged. It is also helpful in the distribution of the mainspring’s internal tension.

TORQUE LIMITING CROWN RM51

This additional security system prevents from accidental overwinding, which could cause damage to the winding stem or putting extreme pressure on the mainspring barrel. The crown is set with precious stones or semi-precious stones depending on the version.

INTERIOR FLANGES RM51

Upper flange in black carbon fiber, with the hours index set with diamonds. Lower flange in black carbon fiber. with the minutes index in white color.

Characteristics

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