Richard Mille RM 07-02 Pink Lady Sapphire

SAPPHIRE CASE
Crafted from sections of colored sapphire taken from a single block, this case is extremely difficult to machine.

Observing the manufacturing process of a sapphire case highlights the challenge its creation entails, from both an engineering and a 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.

This case highlights the house’s skeletonised movement— in micro blasted white gold for the green and blue sapphire versions, and in 5N red gold for the pink and brown sapphire versions.Movement dimensions: 29.90 x 22.00 mm
