Patek Philippe 5056P Annual Calendar Moon Phase Platinum Gray Dial

The Patek Philippe 5056P-001 Annual Calendar Moon Phase in platinum with a gray dial is a quietly majestic expression of haute horology. Introduced in the late 1990s and produced until 2006, this model was among the first to combine an annual calendar with a moon phase in a Patek Philippe wristwatch. Its 37 mm platinum case, measuring approximately 11 mm thick, houses the automatic caliber 315 S IRM QA LU, a finely finished movement with a 48hour power reserve, Geneva Seal, and Gyromax balance. The slate-gray dial is elegantly appointed with applied Roman numerals, leaf hands, and sub dials for day, month, moon phase, and power reserve, along with a discreet date window. A small diamond set at 6 o'clock on the case adds a signature Patek flourish. This reference enjoys strong collector appeal for its technical innovation, restrained design, and rarity, having been crafted exclusively in platinum. It remains a highly sought after piece for discerning connoisseurs of complications. Like New with Patek Philippe box, setting pin, and Extract from the Archives dated 1999.
