Designer
Jörg Hysek
Jörg Hysek left Rolex and Seiko's European studios to build a design practice in Geneva, giving houses such as Vacheron Constantin, Breguet, Seiko and TAG Heuer their sculptural, architecture-led cases before founding his own brand, HD3.
Historical significance
Oris Big Crown 37 mm Meteorite 18k sits within Oris's Big Crown line, introduced in 1992. It carries the house codes established since 1904 — 18k white gold case, meteorite dial and automatic chronograph — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

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.
