Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
Richard Mille RM 035 40 mm Skeletonised 18k sits within Richard Mille's RM 035 line, introduced in 2001. It carries the house codes established since 2001 — 18k rose gold case, skeletonised dial and in-house automatic micro-rotor — 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.
