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
Roger Dubuis Excalibur Spider 42 mm Green Carbon sits within Roger Dubuis's Excalibur Spider line, introduced in 1995. It carries the house codes established since 1995 — carbon tpt case, green sunburst 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 bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.

Brand history
Roger Dubuis has spent more than 31 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Excalibur, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Roger Dubuis & Carlos Dias established Roger Dubuis in 1995, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Roger Dubuis calibre produced today.
