The Grandmaster Chime reference 6300A-010 was created specially for Only Watch 2019. It stands out as the first and only version of this timepiece ever produced in stainless steel.
The one and only Patek Philippe Grandmaster Chime made in stainless steel.
The Grandmaster Chime is the first Patek Philippe grande-sonnerie wristwatch ever added to the company’s current collection. The grand complication Ref. 6300A-010 unites accomplishment and elegance in this new and unique stainless steel version boasting two dials in rose gold and black ebony. The reversible case, adorned with a guilloched hobnail pattern, is notable for its patented reversing mechanism.
This exceptional grand complication features 20 complications in its stainless steel case, including no fewer than five chiming modes, two of which are patented world firsts: an acoustic alarm that strikes the preselected time and a date repeater sounding the date on demand.
The Grandmaster Chime reference 6300A-010 was specially created for the 2019 Only Watch Auction. It stands out as the first and only version of this exceptional timepiece ever produced in stainless steel. The shine of this metal, rarely used with a Patek Philippe Grand Complication, is particularly striking when combined with the hand-guilloched hobnail pattern which perpetuates the tradition of rare handcrafts. The special words “The Only One”, which appear at 12 o’clock on the auxiliary dial, further enhance the exclusive value of this unique timepiece.
Complicated watchmaking is the supreme test of the designer’s expertise and watchmakers’ skill. Patek Philippe masters all horological complications and has twice this century built the world’s most complicated portable timepiece.
