The Patek Philippe Nautilus ref. 5712/1A-001 in stainless steel, is one of the most iconic Nautilus models as it was originally released as ref. 3712/1A in 2005 and produced for less than a year. Fitted with a date indicator, moon phases and a power reserve indicator, this reference is simply awesome. The Nautilus ref. 5712 stays true to the design cues of the original Nautilus ref. 3700 and its predecessor ref. 3712. The Patek Philippe Nautilus ref. 5712 is available in 18K white gold and 18K rose gold on crocodile strap and in stainless steel with matching stainless steel bracelet like the one we have here.
