Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
Oris Aquis 42 mm Green Sapphire sits within Oris's Aquis line, introduced in 1996. It carries the house codes established since 1904 — sapphire crystal case case, green sunburst dial and automatic chronograph — 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.

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.
