Form and function unite in this Classico Xflat timepiece from Ulysse Nardin. In a limited edition of 88 pieces, the watch features an 18K rose gold case and an eggshell dial showing the hours, minutes, and small seconds, held together by an alligator strap. Making it a truly reliable instrument are its 11 ½" UN-820 caliber, 42-hour power reserve, and 50m water resistance. Its solid case back, pull out crown, and deployment clasp give it a classic appeal.
