Patek Philippe has created a new alliance between Haute Horlogerie and Haute Joaillerie by reinterpreting its most complicated wristwatch in a white gold version set with 118 baguette-cut emeralds (7.87 cts) and 291 baguette-cut diamonds (20.54 cts), using the “invisible setting” technique. Among the 20 complications are five acoustic functions, including two patented world exclusives: an alarm sounding the programmed time and a date-repeater striking the date at will. The reversible double-sided case is distinguished by its patented swivel mechanism, enabling it to be worn with either dial visible. This watch is accompanied by white gold cufflinks set with a row of baguette-cut emeralds.
