The RM011 Silicon Nitride is the revolutionary new timepiece from Swiss luxury watchmaker Richard Mille. The design of this watch was inspired by Formula 1 racing cars and features an automatic caliber RMAC1 tourbillon movement and a variable geometry rotor which adapts to the user’s activities. Because this watch is made from brown silicon nitride, it is lightweight yet highly resistant to corrosion, wear, and temperature fluctuations. This watch also features an annual calendar, a twelve-hour totaliser, and a sixty-minute countdown function.
