To commemorate the 10th anniversary of the Aquanaut, Patek Philippe released the reference 5167 in 2007 as a significant upgrade of the collection. Featuring a stainless steel case measuring 40 mm, the index at 3 o'clock is replaced with a date aperture, making the watch very practical for everyday use. With an estimate of $25/45,000, this example is on offer from the original owner and complete with box and papers in our Watches Online NY auction.
