Ulysse Nardin Sonata 660-88 Dual Time Zone Alarm Watch
18K white gold Ulysse Nardin Sonata 660-88 is a 42mm mechanical alarm watch with a musical chime/ring. While the alarm is ringing you can see the piston at work – located at the 8 o’clock position & held in place with a blue bridge. The silver ridged dial is overlaid with the register dials: the alarm time set at 2, the GMT/24 hour time zone at 6 and, at 10 o’clock, the countdown indicator for the alarm – the alarm will chime once in 24 hours, the countdown will indicate if the alarm will chime AM or PM. The On/Off indicator is at 9, controlled by the button in center of the left crown. The left crown itself adjusts the date, with GMT buttons on the side to change the time-zone by one hour increments either way. 18K white gold UN deployant buckle. The mechanical automatic movement is warrantied by Aaron Faber for two years.
