Richard Mille RM38-02 Manual Winding Tourbillon Bubba Watson

The RM 38-02 Tourbillon Bubba Watson is the fourth watch of the collection bearing Bubba’s name over the sportsman’s 10 years with the Richard Mille family. Produced in a numbered limited edition of 50 pieces, it is pretty much the watchmaking equivalent of a hole in one. Manual winding tourbillon movement with hours and minutes. The baseplate is machined from Carbon TPT. This material consists of multiple layers of parallel filaments obtained by separating carbon threads. With a maximum thickness of 30 microns, the Carbon TPT layers are saturated with resin then piled onto a special machine that modifies the orientation of the fibres between each layer by 45°. Once heated to 120°C and subjected to a pressure of 6 bars, the Carbon TPT is machined at Richard Mille’s parts factory. Carbon TPT is renowned for its excellent resistance to microcracks and splits. The skeletonised Carbon TPT baseplate is a significant feat of machining. A master component of the RM 38-02, it was subjected to a full battery of extreme tests prior to approval in order to optimise its mechanical properties. This mechanism guarantees greater reliability when subjected to shock and also during movement assembly or disassembly, hence better chronometric results over time. The regulator index is eliminated and a more accurate and repeatable calibration is possible thanks to 4 small, adjustable screws located directly on the balance.
