Ulysse Nardin Blast 45mm Titanium — Blue Dial | Ref. 1723-400-03

Beware of Blast — the name is not hyperbole. The 45 mm Blast collection represents Ulysse Nardin's most aggressive fusion of haute horlogerie and avant-garde industrial design, a philosophy rooted in the brand's InnoVision laboratory where silicon, ceramic, and unconventional architectures are stress-tested before entering series production. This titanium-cased reference with blue dial carries the Blast's signature aesthetic language: sweeping, almost aggressive case angles that draw the eye across each surface plane, creating a watch that reads as kinetically charged even at rest. Titanium at 45 mm and 13 mm thick offers a substantial wrist presence without the oppressive weight of steel or precious metal.

The Calibre UN-172 self-winding movement is the horological core of this reference, delivering approximately 72 hours of power reserve — sufficient for a long-haul journey or an extended weekend without winding. The movement reflects Ulysse Nardin's commitment to in-house manufacture: components are produced at the brand's Le Locle atelier using the same precision machinery that has served the watchmaker since its marine chronometer era. The blue dial interprets the Blast aesthetic through a layered, architectural surface treatment that catches light differently at each angle of observation, creating the impression of depth and movement in what is ultimately a static surface.

A leather strap provides the Blast's sporting character with a measure of refined versatility — an acknowledgement that this watch occupies a space between high-complication dress piece and assertive sport reference. Water resistance to 50 metres covers everyday exposure without compromising the strap's longevity. At $44,530 the Blast positions itself as a statement piece for the collector whose tastes run toward architectural boldness rather than horological classicism — a watch that announces the wearer's awareness of the avant-garde current running through contemporary Swiss manufacture, backed by a heritage extending to 1846 and the most technically ambitious escapement research programme in independent watchmaking.
