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
Omega De Ville 41 mm Ice Grade sits within Omega's De Ville line, introduced in 1950. It carries the house codes established since 1848 — grade 5 titanium case, ice blue dial and in-house manual-winding — 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
Omega has spent more than 178 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Speedmaster, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Louis Brandt established Omega in 1848, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Omega calibre produced today.
