Ulysse Nardin Blast Dual Time

Ulysse Nardin's Blast Dual Time, reference 243-20/42, is a steel-cased GMT watch measuring 42 mm across. The case stands 10.05 mm thick and pairs with a black dial carrying Roman numerals. A sapphire crystal covers the dial, and the self-winding calibre UN-24 drives the watch from within, with 42 hours of power reserve. Beyond the second time zone, the movement adds a date function and small seconds at the sub-dial. The dual time display makes it practical for travel across zones without losing track of home time. An alligator leather strap closes the piece. Water resistance is set at 50 metres.
