Watchmaker Richard Mille introduces a new version of the popular RM 011, created with brown silicon nitride.
A hard yet lightweight material, silicon nitride is the secret weapon in the engineering Formula 1 racing cars.
Never before used in watchmaking, the material is used in the automobile industry to ensure exceptional accuracy, rigidity and lightness in valves, turbocharger rotors and other parts. An extremely hard material (1,500 Vickers), silicon nitride has a high resistance not only to wear and corrosion, but also to severe temperature variations.
Inspired by these cutting-edge technologies, silicon nitride is used for the bezel and case back of the RM 011. These parts are machined with diamond tools that are capable of performing the complex operations required by the barrel shape, whilst guaranteeing strict tolerances and an exceptional case finish, completed with satin-brushing and microblasting. The satin-brushed case-middle, crown and push-pieces are made of 18-carat red gold, and the push-piece guards from polished grade 5 titanium.
The RM 011’s automatic caliber RMAC1 is now equipped with a flyback chronograph function that allows a timing operation in progress to be restarted without stopping the mechanism.
This watch also boasts a variable geometry rotor, exclusive to Richard Mille, which optimises the winding of the barrel by adapting it to the user’s activities.
The RM 011 Brown Silicon Nitride is available from Richard Mille boutiques and the brand’s retailers.
