Overview
The Richard Mille RM 055 Bubba Watson is a skeletonized sport watch developed in collaboration with the two-time Masters champion golfer. Its tonneau-shaped case pairs white ceramic with titanium to achieve a construction that is simultaneously lightweight and highly resistant to wear. The fully open dial exposes the Cal. RMUL2 movement, inviting close study of the hand-wound architecture within.
History
Richard Mille introduced the RM 055 in 2011 as part of its ongoing ambassador partnership with Bubba Watson, whose unconventional, self-taught style aligned with the brand's ethos of technical audacity. The reference remained in production for nearly a decade, spanning Watson's most prominent years on the PGA Tour, including his Masters victories. White ceramic was a deliberate material choice, echoing the color associated with Watson's signature pink-shafted driver while offering exceptional surface hardness. The RM 055 stands as one of the longer-running ambassador references in the RM 055 line.
Notable points
- Case dimensions of 49.9 × 42.7 mm follow Richard Mille's characteristic oversized tonneau geometry, designed to sit flush and ergonomically on the wrist during athletic movement.
- The white ceramic and titanium case construction combines ceramic's scratch resistance with titanium's low density, keeping overall weight minimal for a watch of this size.
- Cal. RMUL2 is a hand-wound calibre developed within the Richard Mille ecosystem, visible in its entirety through the skeletonized dial and caseback.
- The collaboration with Bubba Watson reflected Richard Mille's broader strategy of partnering with elite athletes across disciplines beyond traditional watchmaking affinities.
- Production spanned approximately 2011 to 2020, making the RM 055 Bubba Watson one of the more enduring references within the RM 055 collection.
