A unique piece of Patek Philippe Grandmaster Chime Reference 6300A made the biggest contribution with an incredible amount of 31 Million Swiss Francs – the first and only Grandmaster Chime in steel. It is to mention, that steel is rarely ever used at Patek in terms of case material, and particularly uncommon for a grand complication.

The Grandmaster Chime is part of the manufacture’s regular collection in white gold since 2016 and with 20 complications the most complex wristwatch of Patek Philippe. Amongst the complications are an alarm that strikes the preprogrammed alarm time and a date repeater that sounds the date on demand – two patented world premières. The grande complication has a reversing case mechanism with two different dials in rose gold with guilloched hobnail pattern ‘Clous de Paris’ and a dial in black ebony.

Ahead of the auction, there were some speculations already that Patek might break the record this year. The Grandmaster Chime Reference 6300A has therefore replaced the original Rolex Daytona from Paul Newman, which has been with 17 Million Swiss Francs the most expensive wristwatch to date, that has ever been sold at an auction. The highest bidder for Patek’s Only Watch 2019 remains anonymous.
