Ulysse Nardin Sparkling Blast

After the launch of the BLAST collection at the Geneva Watch Days, Ulysse Nardin presents SPARKLING BLAST, an astonishing high jewelry timepiece, featuring an open worked automatic tourbillon and embellished with what appears to be a mosaic of hundreds of shattered shards of mirror. Made from expertly, geometrically cut diamonds, each faceted stone is sculpted by hand.

The delicate mechanical tourbillon movement of the watch is visible through the face, a tour de force of skeletonized handiwork perfected over a century and a half of master craftsmanship at Ulysse Nardin. This new SPARKLING BLAST limited edition, has been created in an exclusive, exceptional and selective edition; three in white gold with a white rubber strap and three in white gold with a deep blue, alligator strap; each model is limited to three watches.

With an Xplosion of 85 distinct and unique cuts of diamonds, this masterpiece is composed of a stunning 211 diamonds for a total weight of 13 carats. The symbolic “X” – trademark of Ulysse Nardin – is also set with sparkling diamonds, embedded directly into the watch face, sealing the seamless look of timeless elegance and luXury. The self-deploying buckle is itself adorned with 1.22 carats of pure brilliance. The crown, bezel and index hands are also set with hand-faceted diamonds. The watch has a water resistance up to 50 meters.

Powered by the UN-172 movement, with a micro-rotor in platinum and a three-day power reserve, this 45 mm skeletonized timepiece is equipped with a 2.5 Hz Silicium flying automatic tourbillon.

The architecture of the watch horns lends itself perfectly to the diamonds set within it. The designers at Ulysse Nardin fashioned the horns after a stealth aircraft, which has a sleek design conceived with stealth technology to avoid detection. These shapes lend themselves expertly to the “broken mirror effect” generated when they are faceted with diamonds.

The gems are positioned in invisible settings to avoid marring the brilliance of their hand-cut majesty and in order to best reflect the ambient light. Each gem is faceted in perfect harmony with the design of the watch. To make their dream vision into reality, the artisans at Ulysse Nardin used this “invisible setting” to show the diamonds in their most favorable light.

Note: All diamonds acquired by Ulysse Nardin comply with the World Diamond Council System of Warranties, which is bound by the rules instated by the Kimberley Process.
