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
Corum Golden Bridge 44 mm Mother-of-pearl Stainless sits within Corum's Golden Bridge line, introduced in 1955. It carries the house codes established since 1955 — stainless steel case, mother-of-pearl dial and automatic, swiss lever escapement — 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 bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history
Corum has spent more than 71 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Admiral, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
René Bannwart established Corum in 1955, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Corum calibre produced today.
