Grandmaster Chime

The undisputed star of Only Watch 2019, Patek’s record- breaking Grandmaster Chime Ref 6300A is an absolute blockbuster of a watch – and not just for its 47.7mm diameter. The first grande sonnerie in the company’s collection not made in a precious metal, it’s powered by a manually wound Calibre 300 movement that comes in a reversible stainless- steel case. As well as its two dials, salmon on the front and ebony behind, it features hours, minutes, 24- hour hand, perpetual calendar ( day, month, year, leap- year and moonphase), day/ night indicator, grande and petite sonnerie, minute repeater, date repeater and alarm. Estimate: US$ 2.5 million-$ 3 million million Actual: US$ 31 million million
