The Henry Graves Supercomplication, 1933 The Henry Graves Supercomplication, 1933

 

Made by Swiss manufacturer Patek Philippe in 1933 the watch, which 15 years ago made a record-breaking sale,  has an estimate of $16.8 million. Its reappearance on the market marks Philippe's 175th anniversary celebrations.

The watch was sold at Sotheby's, New York, in December 1999. Estimated at $3-5 million it exceeded expectations totaling at $11 million, becoming the most expensive at auction.

The incredible watch was commissioned by New York banker Henry Graves in 1925. Following three years of research and another five of work by technicians, the watch was complete. It includes moon phases, power reserve, a perpetual calendar, indications of sunset and sunrise times. The craftsmanship of the watch has only been surpassed by computer-assisted technology.

Sotheby's Worldwide Head of Watches Tim Bourned, and Daryn Schnipper, the Chairman of Sotheby's Watch Division, labelled it, "the Holy Grail of watches."
