Ulysse Nardin takes watch collectors by surprise, once again, and this time it's with its new, in-house developed musical mechanical watch based on another Ulysse Nardin caliber, the UN-690 using silicium technology. The first in this series of limited edition timepieces plays the melody “Strangers in the Night” — the legendary song made famous by Frank Sinatra in 1966. Crooning about a chance romantic encounter, Sinatra enthralled fans around the world; his velvety voice paired with these dreamy lyrics lives on, inspiring the possibility of love. Limited Edition of 99 pieces.
