It has been several years in the making but Ulysse Nardin has found a new way to make sound. Introducing the Blast Hourstriker, an innovative new striking watch that breaks barriers in sound technology. 

The art of marking the time with music has always been a part of Ulysse Nardin’s technical arsenal. It was revived in the 1980s, under the impetus of Rolf Schnyder and given a new lease of life in 2019 when the Swiss Manufacture collaborated with French audio technology company Devialet on the next level of watchmaking acoustics, which was launched in the Classico Hourstriker Phantom.

This year Patrick Pruniaux, Ulysse Nardin’s CEO, has again made the choice to make sound central to the brand’s drive for more futuristic ways to reinterpret traditional watchmaking crafts.

The Blast Hourstriker is powered by the recently fashioned UN-172 movement and has a three-day power reserve. With an automatic tourbillon for the first time within the Ulysse Nardin SKELETON collection and a new tiny yet powerful platinum micro-rotor – visible only from the front of the watch at 12 o’clock – BLAST was 18 months in the making, from conception to creation.

To truly allow the sound of the Blast Hourstriker to resonate, the distinctive 45 mm Blast case was given a black DLC titanium middle, capped with 5N 18-kt rose gold, for improved acoustics. To silence this imposing timepiece with the button located at 8 o’clock on the middle must be pressed and then the ‘On’ or ‘Off’ ” position at the tip of the function selector hand located at 8 o’clock checked.

The three straps that come with the Blast Hourstriker allow its different personalities to be explored. The black high tech, waterproof velvet option emphasizes its aerodynamism, while the alligator brings its more sophisticated side to the fore. In addition, a rubber strap is also available for this model. Whatever you choose, remember the Blast Hourstriker is made to be heard not seen.

Self-Deploying Buckle -Thanks to a new patented 3 blade system that opens in a synchronized manner it snaps open like a couple sharing a dynamic and erotic tango dance. Stunningly easy, powerfully secure.
