The Patek Philippe Grand Complications 5236P-010 In-Line Perpetual Calendar is crafted in a 41.3mm platinum case and styled on a brown leather strap. The opaline rose-gilt dial hosts moon phase capability and in-line perpetual calendar complications that display the year, date, and month in one clean line at 12 o'clock. For a final touch of elegance, a single diamond sets the platinum case in place at 6 o'clock.
