Reinventing Haute Horology. Charting a new course. Ulysse Nardin’s Blast collection takes on this challenge with conviction and determination. With its double X – for exploration – the new Blast Tourbillon Blue & Gold, with its sharp lines and resolute character, takes a decisive step towards watchmaking of the future.

The Blast Tourbillon is driven by a flying tourbillon skeletonized movement with silicium escapement in a modern case. Inspired by the lines of stealth aircraft, this avant-garde watch expresses its full power through the juxtaposition of colours and materials and the perfect integration of all its components. The engine in this new craft was designed and developed by the Manufacture’s master watchmakers in an iterative process, in parallel with the two-tone case that houses it, to ensure both perfect integration and exceptional comfort for the wearer.

Playing with transparency and authenticity, the UN-172 Manufacture calibre houses an automatic silicium flying tourbillon oscillating at a frequency of 2.5 Hz. It also offers a power reserve of three days while it’s nestled in a unique cage that is X-shaped. This allows light to penetrate the open-worked watch, illuminating the extraordinary technical feat that this uncompromising time mechanism represents. The iconic codes that express the unique personality of the Blast collection are all present in this new timepiece: the rectangular frame, the signature «three lugs» that fit perfectly into the strap, the coloured bezel, the verticality of the movement with the barrel, as well as the micro-rotor in platinum at 12 o’clock and the flying tourbillon at 6 o’clock.

Structured with alternating components in rose gold and blue PVD titanium, and featuring both polished and satin-finished surfaces, the powerful 45 mm case is water-resistant to 50 meters. This new model comes with a blue velvet rubber strap along with a rose gold and blue PVD titanium folding clasp.

The new Blast Tourbillon is a clear affirmation of Ulysse Nardin’s innovative prowess. As an independent brand that dares to take its elite watchmaking craftsmanship to unexplored paths, Ulysse Nardin inspires and forges the watchmaking of tomorrow.
