AUTOMATIC PINK SAPPHIRE

SPARKING COMPLEXITY

The 1930s was an innovative period, when the famous Pink Lady drink for women was introduced. This balanced cocktail designed for female members of high society encapsulated a desire to modernize the rather chauvinist customs of clubs and their gentlemen clientele. In the same spirit that sparked the creation of this ladies’ cocktail, the RM 07-02 Pink Lady Sapphire brings a feminine approach to technique, cloaking it in the pink tones of this renowned drink.

Main characteristics

Crafted from sections of pink sapphire taken from a single block, the case of the RM 07-02 is extremely difficult to machine. Observing the manufacturing process of a pink sapphire case highlights the challenge its creation entails, from both an engineering and technical standpoint. There is no room for even a single cutting error. The case requires almost forty days of machining and finishing to meet the uncompromising specifications laid out by Richard Mille. Numerous tests then follow to verify that the brand’s resistance and comfort requirements have been met.

CASE

The bezel, caseband and case back of the RM 07-02 are made from solid blocks of Pink Sapphire. Sapphire is known as a particularly scratch-resistant material with a hardness of 1800 Vickers. Created from crystals of aluminum oxide (Al2O3), its transparency is a result of the purity of composition. Machining these components constitutes the biggest challenge ever faced by Richard Mille— a challenge made all the more difficult as the sapphire machining process is exceptionally delicate. Creating a case of this quality took over 40 days of machining, including 430 hours spent pre-forming the case components and 350 hours polishing the caseband/bezel/case back ensemble.

GEMSET ROTOR WITH VARIABLE GEOMETRY

- Heavy external outside edge and heavy edge ring in 5N red gold - Ceramic ball bearing This rotor with variable geometry enables winding to be adjusted to the owner’s activity level. Adjusting the two weights, which can be slid sideways into the correct position and fixed in place by spline screws, modifies the setting. Inertia of the movement is optimal when the two weights are closer to each other, and the barrel rewinds more quickly. If the weights are positioned at either end of the rotor, the inertia is considerably reduced, resulting in the barrel winding more slowly.

FREE SPRUNG BALANCE WITH VARIABLE INERTIA

This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shocks and also during movement assembly and disassembly, hence better chronometric results over 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.
