Ulysse Nardin Blast Titanium & Ceramic — Black Dial | Ref. 1723-400-3B-BLACK

Beware of Blast — the collection's own declaration of intent — captures with characteristic Ulysse Nardin directness the proposition of this 45mm titanium and ceramic instrument: not a watch for the timid, not a watch for the collector who values discretion above all, but a watch for someone who understands that horological ambition at this level demands a physical presence commensurate with its intellectual seriousness. The titanium and ceramic case construction — 13mm thick, 45mm wide — houses a movement architecture of corresponding ambition, and the rubber strap is the right companion for a piece whose identity is rooted in dynamic activity rather than static display.

Caliber UN-172, the self-winding calibre at the Blast's heart, extends Ulysse Nardin's InnoVision material programme into a 72-hour power reserve specification that provides three full days of autonomy between winding cycles. This is not merely a marketing figure: it reflects the genuine efficiency of a movement whose wheel train geometry and rotor architecture have been optimised through sustained engineering work to minimise energy dissipation and maximise the kinetic energy captured from wrist motion. Silicon escapement components — wheel and pallet fork — operate without lubrication, resisting the magnetic interference that would compromise conventional steel components in everyday urban environments.

The black dial, rendered with the layered visual depth that distinguishes the Blast collection's aesthetic from every other Ulysse Nardin family, creates a surface that is simultaneously matte and dimensional — the light playing across its architecture in a manner that changes with viewing angle and ambient illumination. The rubber strap provides practical wrist compliance and visual coherence with the case's dark surfaces. Water resistance to 50 metres makes the Blast genuinely versatile. This variant, with its rubber strap and pure black dial, is the Blast in its most athletically resolved expression — technical, uncompromising, and entirely consistent with the most ambitious values of the Le Locle manufacture.
