Designer
Emmanuel Gueit
Emmanuel Gueit came from a family of Geneva jewellers and was barely into his twenties when he drew the oversized Royal Oak Offshore in 1993 — a watch the house's traditionalists resisted and collectors turned into an icon.
Historical significance
Richard Mille RM 055 36 mm Green Stainless sits within Richard Mille's RM 055 line, introduced in 2001. It carries the house codes established since 2001 — stainless steel case, green sunburst dial and in-house tourbillon, manual-winding — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

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.
