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
Girard-Perregaux Casquette 41 mm Slate Quartz sits within Girard-Perregaux's Casquette line, introduced in 2000. It carries the house codes established since 1791 — quartz tpt case, slate grey dial and in-house automatic, superlative chronometer — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- 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
Girard-Perregaux has spent more than 235 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Laureato, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Jean-François Bautte established Girard-Perregaux in 1791, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Girard-Perregaux calibre produced today.
