On May 12, 2019, Antigulen held an important modern and antique timepiece auction in Geneva. At auction No. 726, a unique Patek Philippe watch, the Aquanaut Ref.5060 prototype watch, was sold at an eight-fold valuation and sold for 2.72 million yuan.
The watch’s dial and movement are decorated with the words ‘PROTOTYPE’ and ‘LABO’, respectively, and have the ‘comet’ power reserve indicator function (a signature feature of Nautilus Ref. 3710 / 1A). This watch, circa 1996, has a 36 mm stainless steel case, a 330/196 self-winding movement, and a rubber strap with a double folding clasp.
The prototype of the Patek Philippe Ref.5060 was estimated to cost 50,000 to 80,000 Swiss francs before the auction. On the day of the auction, this watch caused fierce competition. After the bid exceeded 100,000 Swiss francs, the bidding was mainly between two bidders. It took 15 minutes and the watch was sold for 330,000 Swiss francs. The total cost is 401,000 Swiss francs, equivalent to approximately RMB 2.72 million, which is eight times the lowest estimate before the auction. (Photo / text watch home Xu Chaoyang)
