Richard Mille RM 039 Tourbillon Aviation E6-B Flyback Chronograph Replica Watch

RM 50-04 The hand-wound RM 50-04 features a light white/cream 44.5mm case, mixed carbon TPT and quartz TPT, with 30-minute split-seconds chronograph, tourbillon, power reserve indicator (max approx. 70 hours), as well as an indication of function and torque. All of this is supported by the brand's new skeletonized RM50-03 movement, which is crafted from carbon TPT and titanium. Tested by Richard Mille to withstand shocks of up to 5000 grams, this wild movement weighs 7 grams. For reference, a US quarter weighs 5.67 grams (for my fellow Canadians, a Toonie is closer to 6.92 grams).
