Manual upper chain RM 50-04 is mixed with carbon white TPT and quartz TPT mixed-made light white / cream 44.5 mm housing, 30 minutes double second pursue time code table, gyro and power storage indication (up to 70 Millimeter) hour), and function and torque indication. Brand's new hollow RM50-03 movement provides support for all this, which is made of Carbon TPT and titanium. After the test of Richard Mille, it can withstand the impact of up to 5000 grams, which is 7 grams of natural movement. As a reference, a quarter of the US is 5.67 grams (for my Canadian compatriots, the weight of the tonna is closer to 6.92 grams).
