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 ProPilot 42 mm Slate 18k sits within Oris's ProPilot line, introduced in 1970. It carries the house codes established since 1904 — 18k yellow gold case, slate grey dial and automatic, swiss lever escapement — 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 movement's bridges are decorated even where they will never be seen once the watch is cased.
  • 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.
