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
Ulysse Nardin Blast 40 mm Blue Quartz sits within Ulysse Nardin's Blast line, introduced in 2018. It carries the house codes established since 1846 — quartz tpt case, blue "grande tapisserie" dial and in-house automatic, superlative chronometer — 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 case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

Brand history
Ulysse Nardin has spent more than 180 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Freak, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Ulysse Nardin established Ulysse Nardin in 1846, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Ulysse Nardin calibre produced today.
