Stepping up in Ulysse Nardin's range
The Blast collection is Ulysse Nardin's argument that high horology and material science need not be strangers. Carbonium — an aeronautical-grade carbon composite developed for aerospace applications — arrives here infused with rose gold, giving the case a warmth that raw carbon refuses. The result is a watch that reads precious without reading heavy, and the 43mm diameter carries more easily on the wrist than that figure suggests. The dial is an architecture lesson. A skeletonised rectangle sits across an X-shaped cage, and the UN-371 beneath it is visible through both faces of the watch. That movement earns its exposure: 173 parts, a silicon escapement resistant to magnetism and wear, and a 96-hour power reserve from a hand-wound calibre built entirely in-house. The blackened hands with their luminous fill give the eye somewhere to land amid all the openwork — without them, reading the time in low light would ask more than it should.

Learn more about Ulysse Nardin
Leonard Ulysse Nardin founded his workshop in Le Locle in 1846 and specialised in marine chronometers — the instruments ships used to determine longitude, where an error of seconds meant an error of miles.
The house became one of the two or three most important chronometer makers in the world. More than fifty navies used Ulysse Nardin instruments, and the company holds an extraordinary record at observatory trials: over four thousand certificates and dozens of gold medals, more precision awards than any other manufacturer.
Its modern era began in 1983 when Rolf Schnyder bought the failing company and partnered with Ludwig Oechslin, a scientist and horological historian. The results were the Astrolabium Galileo Galilei of 1985, which displays the positions of sun, moon, and stars and entered the Guinness records as the most functional wristwatch, followed by the Planetarium and Tellurium — together the Trilogy of Time.
Oechslin also designed the Freak of 2001, arguably the most radical wristwatch of the modern era: no dial, no hands, no crown. The entire movement rotates to indicate the time, and it was the first watch to use silicon components in the escapement, a material now standard across the industry.
The Marine collection continues the chronometer heritage. Kering acquired the brand in 2014.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is hand-wound, so it needs winding every day or two but never a battery.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 96 hours fully wound — enough to sit off the wrist over a weekend and still be running.
Cheapest place to buy
