Designer
Gérald Genta
Gérald Genta (1931–2011) trained as a goldsmith in Geneva and became the most influential watch designer of the 20th century. Working freelance, he sketched the Audemars Piguet Royal Oak overnight in 1970, followed by the Patek Philippe Nautilus, the IWC Ingenieur SL and the Bulgari Bulgari — defining the integrated-bracelet luxury sports watch as a category.
Historical significance
Audemars Piguet Millenary 43 mm Slate 18k sits within Audemars Piguet's Millenary line, introduced in 2021. It carries the house codes established since 1875 — 18k white gold case, slate grey dial and in-house automatic with 22k gold rotor — 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
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.
