The latest Bubba Watson Richard Millie RM005 is the All Grey Boutique edition. The watch consists of an upper bezel crafted using shot-blasted titanium carbide, a technique previous used in watches like the Tourbillon RM 053 Pablo Mac Donough to endure extreme conditions and increase durability. Shot-blasted titanium take on the caseband and caseback, giving the watch its all-grey semblance. The winding caliber RMUL2 boasts a pristine finish with red inner bezel surrounding the skeleton dial, and is capable of withstanding accelerations of over 500 Gs. The All Grey Boutique Edition is limited to 50 pieces.
