Beware of Blast
Supercharged with classic Ulysse Nardin savoir-faire, Blast Tourbillon is an avatar of its time, a potent force of nature. This technological wonder made with rock-hard, masculine lines has ignited a flame that will send seismic shockwaves through the watchmaking world to its core.
"Honestly I think this is probably UN’s next big hit. Given all the features, the design, and the size, it could take on some of the big boys when it comes to ostentatious watches – and I mean that in the most loving sense."
