Patek Philippe reinterprets the design of its most complicated wristwatch by offering it for the first time in a "two-tone" version combining white gold and rose gold, along with brown opaline dials. 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 on demand. 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 featuring a brown opaline center adorned with hand-guilloched hobnail pattern and a rose gold Calatrava cross.
