Housed in a 41.3mm platinum case measuring 11.07mm in height, the 5236P-010 belongs to Patek Philippe's Grand Complications collection and carries a water resistance rating of 30 metres. The case is finished with interchangeable solid and sapphire crystal case backs, allowing the wearer to choose between concealing or revealing the movement within.
The opaline rose-gilt dial is appointed with charcoal gray, white gold applied faceted baton-style hour markers, lending the piece a refined contrast. Beneath the dial, the self-winding Caliber 31-260 PS QL orchestrates an in-line perpetual calendar, displaying day, date, month, leap year, and day/night indication through apertures, alongside moon phases and small seconds.
The watch is worn on a hand-stitched shiny chocolate brown alligator leather strap with square scales, secured by a platinum fold-over clasp that complements the case material throughout.
