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
Bulgari Bulgari Bulgari 40 mm Mother-of-pearl Stainless sits within Bulgari's Bulgari Bulgari line, introduced in 2017. It carries the house codes established since 1884 — stainless steel case, mother-of-pearl dial and in-house automatic, chronometer certified — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

Brand history
Bulgari has spent more than 142 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Octo Finissimo, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Sotirio Bulgari established Bulgari in 1884, working from Italy at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Bulgari calibre produced today.
