Patek Philippe Annual Calendar Full set 2025

Patek Philippe Complications reference 5905R-010 housed in a 42mm 18k rose gold case characterized by its sophisticated concave bezel and elegant hollowed lugs. Its deep sunburst blue dial is adorned with applied, faceted rose gold baton markers and matching dauphine hands treated with luminescent coating for excellent readability. The dial features three signature arc-arranged apertures between 10 and 2 o'clock displaying the day, date, and month. Positioned at 6 o'clock is a prominent 60-minute chronograph counter paired with a discreet day/night indicator. Underneath the dial beats the in-house, self-winding Caliber CH 28-520 QA 24H, a mechanical marvel featuring a traditional column-wheel design, a vertical disk clutch, and a 21K gold central rotor. Visible through an exhibition sapphire crystal caseback, this movement delivers up to a 55-hour power reserve. Completing this luxurious aesthetic is a hand-stitched, shiny dark blue leather strap secured by a matching rose gold prong buckle.
