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
De Bethune DB28 42 mm Green Sapphire sits within De Bethune's DB28 line, introduced in 2002. It carries the house codes established since 2002 — sapphire crystal case case, green sunburst dial and in-house automatic with 22k gold 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.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

Brand history
De Bethune has spent more than 24 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's DB28, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
David Zanetta & Denis Flageollet established De Bethune in 2002, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every De Bethune calibre produced today.
