Heir to a great Patek Philippe classic launched in 1941, the Reference 5270 perpetual calendar chronograph is now available in platinum for the first time. Its golden opaline dial, displaying the day and the month in a double aperture at 12 o’clock and an analog date at 6 o’clock, combines a hint of vintage elegance with great legibility. The chronograph movement, with its classic architecture – horizontal clutch, column wheel and manual winding – features six patented innovations.
