Historical significance
Roger Dubuis Monovortex 40 mm Green 18k sits within Roger Dubuis's Monovortex line, introduced in 2013. It carries the house codes established since 1995 — 18k rose gold 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
- 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.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

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.
