Grandmaster Chime
Ref. 6300A "Only Watch"
In November 2019, a unique stainless steel Patek Philippe Grandmaster Chime sold at the Only Watch charity auction in Geneva for CHF 31,000,000 — approximately $31 million. This is the most expensive wristwatch ever sold at auction. The buyer has never been identified. The proceeds funded research for Duchenne Muscular Dystrophy. The watch has 20 complications. Its movement contains 1,366 components. Development required approximately 100,000 working hours — enough for one person to work continuously for 50 years. Patek wrote a 200-page technical manual for it. The standard white gold production version costs approximately $2.6 million. This steel version was the only one ever made. It will never be made again. The inscription on the alarm subdial reads: "The Only One."
One watch. One auction. One night in Geneva. The gavel came down at CHF 31 million. The buyer's identity remains unknown. The inscription reads "The Only One." It is.
