At 49.4 mm in 18K white gold, the Grandmaster Chime's double-sided reversible case conceals two distinct dials connected by a patented swivel mechanism. One face presents a classic time display; the other reveals the full complication side finished with a black dial bearing Breguet numerals beneath a sapphire crystal.
The hand-winding movement powers 20 complications in total, among them five acoustic functions that include two world exclusives: a programmable alarm and a date-repeater. A sapphire case back offers a view of the caliber within, showcasing the level of hand-finishing consistent with Patek Philippe's most ambitious horological undertaking. A black leather strap pairs with the white gold case.
The case and bezel are set via the invisible setting technique with 118 baguette-cut emeralds totaling 7.87 carats and 291 baguette-cut diamonds totaling 20.54 carats. This example is new, offered with full box and papers, and accompanied by a pair of matching white gold cufflinks set with baguette emeralds.
