A dual-time-zone watch is one of the most practical and attractive complications in horology, designed for travelers and anyone who makes the jump from one time zone to another on a regular basis. Set in the classic Avenue of Americas case, the Serenade also features day-and-night indicators for each of the two time zones as well as a date function at six o’clock. Like others in the Avenue of Americas line, the Serenade dials have silver guilloché, Arabic scripted numerals, cathedral hands, and a 34 x 44 mm curved, rectangular case. Cases are available in 18 kt. rose gold and 18 kt. white gold. The automatic movement features a white-gold rotor; the matching folding clasps are also made of white gold.
