Ulysse Nardin Blast Tourbillon 45mm Titanium Blue

Igniting a new era of high-tech horological architecture, the Ulysse Nardin Blast Tourbillon (Ref. 1723-400/03) is a fierce synthesis of stealth aircraft-inspired geometry and cutting-edge mechanical art. Housed in an imposing 45 mm case crafted from sandblasted and satin-finished titanium, the watch features sharp, tessellated lugs designed to mimic the aerodynamic facets of modern stealth fighters. Framing the openwork dial is a rich blue titanium bezel that adds an intense pop of contrast to the industrial grey case.

At the center of the watch lies a bold, multi-layered dial structure defined by a prominent blue rectangular bridge and interlocking double "X" motifs that clamp the movement like a geometric cage. At 6 o'clock, a mesmerizing flying tourbillon features an advanced silicium escapement wheel, anchor, and balance spring operating at a steady 2.5 Hz. Balancing the dial at 12 o'clock is a visible platinum micro-rotor mounted directly above the mainspring barrel. Powered by the in-house automatic Calibre UN-172, this high-performance movement delivers an impressive 72-hour power reserve. The timepiece is paired with a blue alligator leather strap lined with rubber for optimum comfort, secured by a titanium folding clasp.
