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

Audemars Piguet Royal Oak Offshore Chronograph 42Mm Men's Watch sits within Audemars Piguet's Royal Oak line, introduced in 2011. It carries the house codes established since 1875 — stainless steel bracelet case, white dial with blue subdials dial and automatic chronograph calibre — 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.

Brand history

Audemars Piguet has spent more than 151 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Royal Oak, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.

Jules Louis Audemars & Edward Auguste Piguet established Audemars Piguet in 1875, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Audemars Piguet calibre produced today.
