The RM 39-01 is a follow-through of the RM 039 Aviation watch, a tourbillon flyback calibre that contains more than 1,000 parts. The RM 39-01 movement is designed as a flight navigation instrument. This highly technical watch is a modern interpretation of the E6B slide rule, invented in the 1930s in the United States by Lieutenant Philip Dalton to help pilots navigate in the sky.
Watch and engineering geeks will love this watch (so do I). The number of complications made available is mind boggling and I bet the instruction manual is as thick as the Yellow Pages!
The E6B slide rule features a fixed bezel and bi-directional rotating bezel, both marked with several complex indications. It can be used to read and calculate fuel consumption, flight times, ground speed, density altitude and wind influence, and to convert units of measurement (knots/kms/gallons/ litres/feet/kgs/lbs) quickly.
The new RM 39-01 provides pilots with a practical backup in case their main instruments cocks-up!
The RMAC2 automatic caliber, which runs RM 39-01, features UTC and countdown functions, a flyback chronograph, a date at 12 o’clock, a month display and a variable geometry rotor. It has almost 620 components and 62 jewels, with a power reserve of 50 hours. This caliber also comes with a special function-locking mechanism. In order to prevent any accidental in-flight activation of the chronograph, Richard Mille has incorporated a locking crown which, by turning the ring, fixes the pushers and crown in place. The green and red markers indicate whether this is deactivated or running.
