Designer
Gérald Genta
Gérald Genta (1931–2011) trained as a goldsmith in Geneva and became the most influential watch designer of the 20th century. Working freelance, he sketched the Audemars Piguet Royal Oak overnight in 1970, followed by the Patek Philippe Nautilus, the IWC Ingenieur SL and the Bulgari Bulgari — defining the integrated-bracelet luxury sports watch as a category.
Historical significance
Richard Mille RM 055 RG CA TPT Bubba Watson Diamond Set Black Edition sits within Richard Mille's RM 055 line, introduced in 2022. It carries the house codes established since 2001 — 18k rose gold case, blue sunburst dial dial and automatic chronograph calibre — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.

Brand history
Richard Mille has spent more than 25 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's RM 011, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Richard Mille & Dominique Guenat established Richard Mille in 2001, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Richard Mille calibre produced today.
