Ulysse Nardin Voyeur Minute Repeater

Ulysse Nardin's Voyeur Minute Repeater, reference 739-61/VOYEUR, has a platinum case measuring 42 mm across. The dial sits under a sapphire crystal and pairs with a black dial and an alligator leather strap. Inside is the manual-winding calibre UN-73, with a power reserve of 36 hours. This is a limited edition, one of only 18 pieces made. Its principal complication is the minute repeater, chiming the hours, quarters and minutes on demand. The movement and its striking mechanism are what set this piece apart from a standard time-only watch. Water resistance is modest for the type: the case holds to 30 metres, enough for everyday wear but not for diving.
