Ulysse Nardin Executive Dual Time Rose Gold — Blue Dial | Ref. 242-20/43

Dual-time complications achieve their highest expression when the mechanism serves the wearer's actual professional life rather than providing a merely decorative second time zone that is never used. The Ulysse Nardin Executive Dual Time 'Beware of Blast' in 42mm 18K rose gold is a watch built for the genuinely international professional — its Caliber UN-24 offering second time zone quick-setting as a seamless operational function rather than a buried complication requiring crown withdrawals and cautious setting sequences. The 'Beware of Blast' designation acknowledges the aesthetic debt this Executive reference owes to the Blast collection's visual intensity, channelling that boldness into a precious-metal case.

Caliber UN-24 is Ulysse Nardin's dedicated dual-time self-winding calibre, its approximately 42 hours of power reserve sustaining continuous operation through the multi-day international travel schedules that this complication is designed to support. The second time zone quick-setting function — a refinement that allows the wearer to advance or retard the secondary display independently of the main timekeeping train — is the complication's essential practical advantage, and it reflects the same functional discipline that Ulysse Nardin has applied to its dual-time architecture since the Classico Lady Dual Time introduced similar principles. The leather strap with pin buckle provides a traditional wrist presentation appropriate to the rose gold case.

The 18K rose gold case in its 5N alloy form brings the warm, distinctive tone that this alloy's elevated copper content produces — a tone that complements the blue dial's deep saturation with a colour contrast that reads as authoritative rather than merely colourful. Water resistance to 50 metres covers daily exposure without anxiety. The 42mm case diameter positions the Executive Dual Time at the assertive end of the dress-watch spectrum — large enough to read the dual-time display effortlessly, prestigious enough in its material register to justify its place in a serious collection. For the collector whose professional life spans multiple time zones, this rose gold Executive Dual Time is a watch of genuine biographical significance.
