Patek Philippe Nautilus Moon Phase

About this reference

The Patek Philippe Nautilus 5712/1A-001 in stainless steel was introduced in 2006 to commemorate the 30th anniversary of the Nautilus collection and remains in current production. Collectors prioritize this reference for its ultra-thin 8.52mm case profile and the caliber 240 PS IRM C LU, an automatic movement featuring a 22k gold micro-rotor. The asymmetrical dial layout includes a power reserve indicator, moon phase, and pointer date, set against a blue-grey gradient finish with horizontal embossing. Unlike the standard 5711, the 5712 features a four-part case construction and a sapphire crystal caseback. On the secondary market, prices typically range from $90,000 to $120,000 depending on condition and provenance. A notable production variant is the "Geneva Seal" version produced between 2006 and mid-2009, which preceded the transition to the proprietary Patek Philippe Seal found on modern examples.
