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
Citizen Attesa 41 mm Mother-of-pearl Ceramic sits within Citizen's Attesa line, introduced in 1998. It carries the house codes established since 1918 — ceramic case, mother-of-pearl dial and automatic, 24 jewels — 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
Citizen has spent more than 108 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Eco-Drive, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Kamekichi Yamazaki established Citizen in 1918, working from Japan at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Citizen calibre produced today.
