Patek Philippe brilliantly reinterprets Reference 5374 — a combination of two highly sought-after major complications — in a new platinum Haute Joaillerie version with a blue-lacquered dial. The case with its subtle play on curves is paved with baguette-cut diamonds tracing a luminous geometrical pattern. The concave bezel adorned with a double row of baguette diamonds forms a perfect circle. The dial flange is also set with baguette diamonds, with baguette blue sapphires on the hour-markers. This original design forms an “amphitheater” around the dial and creates a spectacular depth effect. The visual balance of the perpetual calendar indications shown by hands, standing out against the blue-lacquered background with black-gradient rim, is thus particularly highlighted.

Its self-winding mechanical Caliber R 27 Q is equipped with a minute repeater mechanism chiming on two “cathedral” gongs wrapped almost twice around the movement and producing a deep, rich sound.
