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
Vacheron Constantin Patrimony 41 mm Green Carbon sits within Vacheron Constantin's Patrimony line, introduced in 1993. It carries the house codes established since 1755 — 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 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
Vacheron Constantin has spent more than 271 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Overseas, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Jean-Marc Vacheron established Vacheron Constantin in 1755, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Vacheron Constantin calibre produced today.
