The latest reinterpretation of the brand’s RM 011 model presents a unique new colour thanks to the first use of brown silicon nitride in a watch case. Measuring 1,500 on the Vickers hardness scale, this material is resistant to wear, corrosion and temperature variations and is also very lightweight. It is used in the automobile industry to make components such as turbocharger rotors. This new material encases the RMAC1 self-winding tourbillon movement with flyback chronograph, 60-minute countdown function and annual calendar.
