The Classic Dual Time Enamel from Ulysse Nardin uses an in-house movement (the calibre UN-324) with silicon technology and an eggshell dial in Grand Feu enamel, made by Donzé Cadrans. Dual Time adjustment pushers are located at 8 and 10 o'clock. When pressed, they adjust the hour hand to a different time zone while home time, located at 9 o'clock, continues its cycle. Adjusting the date is also very simple: the dial is integrated into the crown and this allows the setting mode to be changed without pulling out or pushing in the crown itself.
It is made of steel with an alligator strap.
