Ulysse Nardin Blast Dual Time

Ulysse Nardin's Blast Dual Time, reference 243-20/43, is a steel-cased GMT watch measuring 42 mm across. The case stands 10.05 mm thick and pairs with a blue dial carrying Roman numerals. Inside is the self-winding calibre UN-24, with 34 jewels and a 42-hour power reserve, visible through a sapphire crystal. Beyond the second time zone, the movement adds a date function and small seconds at the dial, giving the wearer a compact read of home and local time together. An alligator leather strap closes the piece, keeping the watch light on the wrist despite its steel case. Ulysse Nardin rates the case to 50 metres, enough for daily wear without much worry.
