Patek Philippe Grandmaster Chime Ref. 6300GR-001

Since the manufacture’s foundation in 1839, Patek Philippe has made its mark as one of the greatest specialists in striking watches. Its supreme mastery was confirmed in 2014 by the launch, as a limited edition, of the Patek Philippe Grandmaster Chime – the most complicated Patek Philippe wristwatch, with 20 complications. This timepiece, which joined the current collection in 2016, is particularly notable for its five chiming modes, including an alarm striking the pre-selected time, and a date repeater striking the date on demand.

The manufacture is reinterpreting the design of the double-face reversible case, endowed with a patented rotation mechanism, by presenting it for the first time in a bicolor version combining white gold and rose gold. This new Patek Philippe Grandmaster Chime Reference 6300GR-001 also stands out by its two brown opaline dials, with a hand-guilloched Clous de Paris or hobnail pattern on the side displaying the time of day, and its two-tone chestnut brown patinated alligator strap and bicolor folding buckle.

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.
