Overview
White Quartz TPT® case with mechanical G-force indicator
The RM 38-01 was developed for golfer Bubba Watson around a manually wound tourbillon movement incorporating a mechanical G-force sensor. Positioned beneath 12 o’clock, the indicator measures acceleration generated during a golf swing on a scale extending to 20 G. A dedicated pusher at 9 o’clock resets the indication.
This version uses White Quartz TPT® case components combined with titanium. The openworked construction exposes the RM38-01 calibre, its tourbillon and the mechanical G-force measuring system.
