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 Tourbillon RM025 AN CA TI Chronograph Diver 49.7mm Black Dial Mens Watch sits within Richard Mille's Mille Tourbillon line, introduced in 2021. It carries the house codes established since 2001 — 18k rose gold case, silvered opaline dial dial and automatic chronograph calibre — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

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.
