This Patek Phillipe was only made once and is from 1936. It is 55mm in diameter. It is a pilot’s watch and displays the time in angular minutes. It sold at a Christie’s auction in Geneva earlier in May for $1,734,862. The watch came unnannounced, not even mentioned in the program for the auction, and was sold to a private Swiss Museum.
