AN ARTISTIC CREATION TO CELEBRATE ‘CROUCHING TIGER, HIDDEN DRAGON II’

Richard Mille and Michelle’s collaboration began in 2011 with the creation of the RM 051 Phoenix Tourbillon, a symbolic timepiece in which she was intimately active. Michelle desired to reiterate the concept of forms and shapes integrated within the watch’s movement, this time with a visual scene centered on the symbolic themes of the Tiger and the Dragon.

Main characteristics

Created from 3N red gold, the figures are carved and incised entirely by hand.
Special miniature tools were specifically made for the specific artistry required in the physical realization of these two creatures.

Limited edition of 20 pieces in 18K white or red gold.

01
BASEPLATE AND BRIDGES ARE MADE OF GRADE 5 TITANIUM
These components are in grade 5 titanium this provides the whole assembly great rigidity, as well as precise surface flatness which is essential for the perfect functioning of the gear train.
The skeletonised baseplate and the bridges have been subjected to intensive and complete validation tests to optimize their resistance capacities.

CALIBER RM51-01 Manual winding tourbillon movement with hours, minutes and power reserve indicator.

TIGER AND DRAGON ADORN THE MOVEMENT A tiger and dragon in red gold are integrated into the movement. Created from 3N rose gold, the figures are carved and incised entirely by hand. Special miniature tools needed to be made for the specific artistry required in the physical realization of these two creatures. To increase the realism of these special animals, a long and painstaking process of hand finished micro painting was executed, also including the unseen parts of these two marvelous entities.

BARREL PAWL WITH PROGRESSIVE RECOIL

This device permits a profitable winding gain (circa 20 %), especially during the winding start. It is also helpful in the distribution of the mainspring’s internal tension.

CASE

The three-part barrel-shaped case is highly curved which means the watch is comfortable to wear but considerable time is required for its production and quality control. The ergonomic and visually distinctive curvature of the case is typical of all Richard Mille timepieces, requiring absolute precision and a total lack of tension in the metal. These requirements for the case design are based on a year’s research and development. The characteristic tonneau shape of the RM 51-01 requires no fewer than 47 preliminary stamping operations including 21 for the tamping before production actually can begin. 4 hours of machining followed by more than 260 milling procedures are required to produce the RM 51-01 case with a further day spent on finishing which entails grinding, satin brushing and polishing. The tripartite case is water resistant to 50 meters, ensured by 2 Nitril O-ring seals. The case is assembled with 12 spline screws in grade 5 titanium and abrasion resistant washers in 316L stainless steel.

FREE SPRUNG BALANCE WITH VARIABLE INERTIA

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. The regulator index is eliminated and a more accurate and repeatable adjustment is possible thanks to 4 small adjustable weights located directly on the balance.

TORQUE LIMITING CROWN

This additional security system prevents from accidental overwinding, which could cause damage to the winding stem or putting extreme pressure on the mainspring barrel.
