The Patek Philippe Grandmaster Chime 6300A-010 is one of the most prestigious and valuable timepieces ever created. Introduced in 2019 as a one-of-a-kind watch for the Only Watch charity auction, it sold for a record-breaking $31 million, making it the most expensive watch ever sold at auction. The Grandmaster Chime is renowned not only for its price but also for its technical complexity and artistic craftsmanship, making it a true masterpiece in the world of haute horology.
The Grandmaster Chime 6300A-010 was created to celebrate Patek Philippe’s 175th anniversary. It is a reversible wristwatch with two dials, one in rose gold and the other in black ebony, allowing the wearer to flip the case depending on the desired look. The watch features an 18-carat white gold case with intricate hand engravings, highlighting the brand’s commitment to exceptional detail and craftsmanship.
What sets the Grandmaster Chime apart is its complex movement, which includes 20 complications—a term used to describe additional features beyond basic timekeeping. These complications include minute repeaters, a perpetual calendar, a moon phase display, a day-night indicator, and dual time zones. The watch also boasts five chiming functions, including two patented world-firsts: an alarm that strikes the time and a date repeater that chimes the date on demand.
The “Only Watch” edition of the Grandmaster Chime, the 6300A-010, is unique in that it is the only version made in stainless steel, a material rarely used by Patek Philippe for its high-end watches. The words “The Only One” are engraved on the case, emphasizing its exclusive status. The watch was specifically crafted for the Only Watch auction, which raises funds for research into Duchenne muscular dystrophy.
The $31 million sale price not only shattered records but also reinforced Patek Philippe’s reputation as one of the world’s most prestigious watchmakers. The Grandmaster Chime 6300A-010 is a symbol of luxury, innovation, and charitable generosity, representing the pinnacle of watchmaking artistry.
This iconic timepiece is more than just a watch—it’s a work of art that showcases centuries of craftsmanship, technological achievement, and timeless elegance.
