The Patek Philippe Annual Calendar Rose Gold Silver Dial 38mm Ref. 5396R-001 presents a 38.5mm rose gold case with a silvery opaline dial, completed by faceted obus-style hour markers and dauphine hands in rose gold for standout clarity. This model features an annual calendar with double day and month apertures at 12 o’clock, a date display at 6 o’clock, and a 24-hour subdial with moon phases, offering calendar precision and ease of use that requires correction just once a year. Powered by the self-winding calibre 26-330 S QA LU 24H, the movement includes a 21K gold central rotor, 34 jewels, Gyromax balance, and a Spiromax balance spring, achieving a frequency of 28,800 vph and a power reserve between 35 and 45 hours. The chocolate brown hand-stitched alligator strap with a rose gold fold-over clasp completes the refined look, and a sapphire caseback showcases the intricate finishing and prestigious Patek Philippe Seal.
