Ulysse Nardin Blast Titanium and Ceramic — White Dial | Ref. 1723-400-3B/00

The Blast collection's white-dialled titanium and ceramic edition represents an interesting counterpoint within an already architecturally assertive family: where the Blast's oceanic blue expressions lean into the brand's Marine heritage, the white dial creates a different dialogue — the stark luminosity of the white surface against the grade-5 titanium and ceramic case reading as an almost minimal statement within a 45mm case architecture that is anything but understated. The ceramic component introduces a material whose hardness and scratch-resistance complements titanium's exceptional strength-to-weight ratio, producing a composite case structure whose surface integrity will outlast that of conventional stainless steel by a significant margin.

Caliber UN-172 provides the mechanical heart of this Blast: a self-winding movement delivering approximately 72 hours of power reserve — three full days of autonomy that reflects the movement's optimised energy architecture. The extended power reserve is not merely a marketing datum; it reflects a winding efficiency and energy management philosophy derived from Ulysse Nardin's InnoVision research programme, in which the relationship between rotor geometry, mainspring capacity, and wheel train friction is treated as an engineering problem rather than a specification box to be ticked. The 13mm case thickness is a direct consequence of the movement's full architectural expression; no dimension has been sacrificed for profile elegance.

The white dial surface within the Blast's architectural case language creates a display of considerable visual interest: the dial's luminosity is not that of a simple lacquered surface but of a material that reflects and distributes light across the case interior. The rubber strap is the right companion — its material compliance providing the wrist contact that a 45mm case of titanium and ceramic demands for secure, comfortable daily wear. Water resistance to 50 metres accommodates active wear without restriction. At its price point, this white-dialled Blast represents an exceptional entry into Ulysse Nardin's most technologically demonstrative collection, a piece that rewards the collector who understands that bold design and genuine mechanical substance are not competing values.
