DESCRIPTION

In 2005 Patek Philippe released the 3712/1A which was a predecessor for the 5712/1A for only one year, making it one of the rarest timepieces in the Nautilus collection. The 3712/1A has a cushion-shaped stainless steel case that is 39mm in diameter and 9mm thick with an exhibition case back, a sapphire crystal, a screw-down crown, and a fixed stainless steel bezel. The dial features the beloved blue-black gradient dial with index hour markers and three sub-dials. The 3712/1A is powered by the self-winding 240 PS IRM C LU caliber which has date, small seconds and moon phase functionality with a power reserve of 48 hours. The case is paired with the classic nautilus stainless-steel bracelet with a double fold-over clasp. It has a water resistance of 60 meters (197 feet).
