Ulysse Nardin Executive Dual Time Steel — Black Dial | Ref. 243-20-42

Practicality and Swiss horological ambition are not competing values in the Ulysse Nardin Executive Dual Time — they are the same value expressed at different levels of resolution. The 42mm stainless steel case of this 'Beware of Blast' Executive hosts Caliber UN-24, a self-winding movement whose second time-zone quick-setting function represents a specific and considered answer to the requirements of international business travel: the ability to reset a second meridian instantaneously, without disrupting the primary time display, with a mechanism that is both reliable and intuitive to operate. This is watchmaking in the service of real life rather than horological theatre.

Caliber UN-24 produces approximately 42 hours of power reserve from its self-winding architecture — adequate for the travel schedule that the complication is designed to support, and comfortable for the weekend break from the watch that modern wearing patterns often involve. The second time-zone display is integrated with the legibility discipline that characterises the Executive collection: two time zones, clearly differentiated, each reading independently without visual interference from the other. This is the core challenge of any dual-time design, and the UN-24's dial layout resolves it with the directness of a movement built for use rather than exhibition.

The black dial and stainless steel case combination is the most versatile expression in the Executive Dual Time range — neither too formal nor too sporting, readable in conference rooms, airports, and evening settings with equal authority. A leather strap with pin buckle provides the refined wrist presentation appropriate to a business complication, its material compliance offering comfort during long-haul travel. Water resistance to 50 metres is more than adequate for the Executive's daily context. At its price point, the stainless steel Executive Dual Time in black is one of the most accessible entry points to genuine in-house Ulysse Nardin manufacture calibre ownership — a watch of real utility and considerable character.
