Patek Philippe Complications 5396R-011 Annual Calendar - Moon Phases

The Patek Philippe 5396R 011 Annual Calendar Moon Phase features a polished rose gold case measuring 38.5 mm in diameter and approximately 11.2 mm thick, water-resistant to 30 m. Its silvery opaline dial displays classic elegance with applied rose gold faceted obus-style hour markers and faceted dauphine hands. The day and month appear in twin apertures at 12 o’clock, while at 6 o’clock, a date window is integrated with a 24 hour subdial and moon phase display, creating a balanced, symmetrical layout focused on legibility and refinement.

Inside the watch is the self-winding calibre 26-330 S QA LU 24H, visible through a sapphire crystal case back. This automatic movement powers the annual calendar, day, date, month, moon phase, 24 hour indication and sweep seconds functions. The mechanism is engineered to require adjustment just once a year at the end of February. It comprises 339 parts, utilises 34 jewels, operates at 4 Hz, and offers a power reserve of 35 to 45 hours. Its precision is guaranteed by the Gyromax balance and Spiromax balance spring under the Patek Philippe Seal standard.
