Richard Mille RM 50-04 Tourbillon Split Seconds Chronograph Ref. RM 50-04

This extremely technical RM50-04 calibre is fitted with a split-seconds chronograph tourbillon and a grade-5 titanium and Carbon TPT® movement that weighs just 7 grams. To combine these complications within a single mechanism required perfect transmission of energy to ensure faultless operation. The need to reduce friction led the research team to improve the profile of the teeth on the barrel and the second wheel pinion. The latter led to an excellent distribution of torque and an optimised output. The combination of the tourbillon escapement and the chronograph paired with the unprecedented fine skeletonisation make this particularly innovative watch the absolute chronograph perfection.
