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 023 Automatic Winding Titanium Skeleton Dial 45Mm Black Leather Straps Men's Watch sits within Richard Mille's Mille Rm line, introduced in 2003. It carries the house codes established since 2001 — titanium case, skeletonized 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.
  • Early production dials show a slightly different minute track, and collectors pay a premium for them.

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.
