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
Breguet Reine de Naples 36 mm Green Sapphire sits within Breguet's Reine de Naples line, introduced in 1976. It carries the house codes established since 1775 — sapphire crystal case case, green sunburst 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 case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history
Breguet has spent more than 251 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Classique, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Abraham-Louis Breguet established Breguet in 1775, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Breguet calibre produced today.
