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
Patek Philippe Grand Complications 43 mm Green Stainless sits within Patek Philippe's Grand Complications line, introduced in 1989. It carries the house codes established since 1839 — stainless steel case, green sunburst dial and in-house tourbillon, manual-winding — 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.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

Brand history
Patek Philippe has spent more than 187 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Nautilus, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Antoine Norbert de Patek & Adrien Philippe established Patek Philippe in 1839, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Patek Philippe calibre produced today.
