Patek Philippe Nautilus 5711/1A-011 With Archive Papers

Patek Philippe Nautilus (Ref. 5711/1A-011) Often referred to by collectors as the "Piano" dial, this reference is distinguished by its silvery-white opaline dial featuring horizontal embossing and contrasting black-oxidized gold indices and hands, which are coated with luminescence for legibility. The 40mm stainless steel case maintains the iconic rounded octagonal "porthole" shape with a slender 8.3mm profile and is water-resistant to 120 meters. Inside, the watch is powered by the self-winding manufacture Caliber 324 S C, visible through a sapphire exhibition caseback and featuring a 21k gold rotor with a 45-hour power reserve.
