THE WORLD’S LIGHTEST SPLIT-SECONDS TOURBILLON CHRONOGRAPH:RM 50-03 McLAREN F1

The RM 50-03 calibre introduces a latest-generation split-seconds mechanism developed by the Richard Mille engineers. The new column wheel operates the different levers of the split-seconds function and optimises the chronograph’s operation. While previous Richard Mille chronographs have traditionally featured a wheel with 8 columns, the one equipping the RM 50-03 now only has 6 columns to ensure optimised simultaneous movement, maximal function locking, and greater adjustment durability. In-depth studies carried out on the function of clamps also led to a new clamp design. The helical spring has also been replaced by a blade on the split seconds wheel of the RM 50-03, a technical decision that reduces the variation in torque when the split-seconds function is activated. All of these developments have considerably improved the timekeeping performance of this tourbillon calibre and have halved the chronograph’s energy consumption while reducing friction on the arbor
