How the In-Line Perpetual Calendar Grand Complication is built

The Patek Philippe In-Line Perpetual Calendar Grand Complication comes in platinum and measures 41mm — platinum is denser than gold, and the wrist knows it. Behind the sapphire sits a blue dial. Sapphire keeps the dial looking new from the front. The back is glass, and the movement runs behind it.

Ref. 5236P-001: movement and functions

Power for the blue-dial In-Line Perpetual Calendar Grand Complication comes from an automatic movement — worn regularly it winds itself and simply runs. Beyond the time it offers a date display, the day spelled out, a day/night indicator for the second zone, a moon phase display, a perpetual calendar, so no correction between years and small seconds on a sub-dial.

Living with the In-Line Perpetual Calendar Grand Complication

The strap fitted is a blue leather strap — the easiest thing on the watch to change. At 41mm, it is a modern full-size case that still clears a shirt cuff. Best suited to a collector who wants the dial to do more than tell the time.

From the listing

Pre-Owned 41.3mm Patek Philippe In-Line Perpetual Calendar Grand Complication (5236P-001)

The Patek Philippe In-Line Perpetual Calendar Grand Complication Ref. 5236P-001 is a remarkable blend of innovation and tradition, introducing a unique linear display for the day, date, and month in a single horizontal aperture beneath 12 o’clock. To achieve this, Patek developed a complex mechanism using four coplanar rotating disks, supported by patented systems that ensure smooth and precise calendar transitions. Housed in a 41.3mm platinum case with a thickness of just 11.07mm, the watch remains elegant and wearable despite its mechanical sophistication. The vertical satin-finished blue dial, shaded with a black gradient at the edges, features applied white-gold markers, moon phase and small seconds at 6 o’clock, along with leap-year and day/night indicators. Powering the watch is the self-winding calibre 31-260 PS QL, equipped with a platinum micro-rotor, beating at 28,800 vph with a power reserve of up to 48 hours. With 503 components and three patents behind its calendar mechanism, the 5236P-001 showcases Patek Philippe’s mastery of technical watchmaking while maintaining a refined, balanced aesthetic. This model is completed with a navy blue alligator strap and platinum fold-over clasp, further enhancing its understated yet commanding presence.
