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
Oris Divers Sixty-Five 36 mm Silvered Platinum sits within Oris's Divers Sixty-Five line, introduced in 1985. It carries the house codes established since 1904 — platinum 950 case, silvered opaline dial and high-beat automatic — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The movement's bridges are decorated even where they will never be seen once the watch is cased.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
Oris has spent more than 122 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Aquis, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Paul Cattin & Georges Christian established Oris in 1904, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Oris calibre produced today.
