Ulysse Nardin Blast Titanium/Ceramic — Black Dial | Ref. 1723-400-3A/Black

Titanium and ceramic in combination represent the materials science frontier of contemporary sports-watch case construction — titanium providing the structural framework with its extraordinary strength-to-weight ratio, and ceramic delivering the hardness and scratch resistance that titanium alone cannot achieve. The Ulysse Nardin Blast 45mm in this dual-material configuration takes the collection's already radical visual proposition and reinforces it with a case architecture whose material sophistication matches its design ambition. The 13mm case thickness is not a compromise but an honest reflection of what Caliber UN-172 requires to perform at its specified capability level.

Caliber UN-172 extends the InnoVision programme's material innovations into a 72-hour power reserve specification — a three-day autonomy that accommodates even the most varied watch rotation schedule without the anxiety of finding the piece unwound. The self-winding mechanism is optimised for efficiency across a broad amplitude of wrist motion, ensuring that the generous reserve is maintained throughout active daily wear. Silicon components in the escapement assembly provide the anti-magnetic, lubrication-free operation that has become the signature of Ulysse Nardin's modern calibres, and the movement's architecture reflects the same willingness to depart from convention that the Freak collection first demonstrated in 2001.

The black dial of this Blast variant delivers maximum contrast within the collection's layered visual grammar — its deep, absorptive surface providing the backdrop against which the movement's architecture can assert itself. Water resistance to 50 metres confirms the genuine sports-watch credentials of a piece whose size and material specification already announce its intention to be worn, not merely admired. A rubber strap provides the ergonomic compliance that a 45mm, 13mm-thick case demands for genuine wrist comfort. The Blast in titanium and ceramic with black dial is the collection's most uncompromising expression — a watch for the collector who regards conventional good taste as an insufficient ambition.
