Patek Philippe Grand Complications 5370P-001 ‘Split-Seconds Chronograph – Black Enamel Dial’ (2021)

Heritage Narrative

The Patek Philippe reference 5370P-001 represents one of the most revered achievements in modern watchmaking: the split-seconds chronograph. Introduced in 2015, it revives one of the manufacture’s most technically demanding and historically significant complications—executed entirely in-house and housed within a platinum case of exceptional refinement.

Its deep black grand feu enamel dial, handcrafted over hours of meticulous firing, contrasts beautifully with applied white gold Breguet numerals and leaf-shaped hands. The platinum case, measuring 41 mm, strikes a perfect balance between presence and elegance, while the movement inside—the Calibre CHR 29-535 PS—is a masterpiece of traditional architecture, visible through its sapphire exhibition back.

This 2021 example, offered complete with its full set of box, certificate, and documentation, remains one of the most desirable contemporary Patek Philippe grand complications—an extraordinary synthesis of mechanical complexity and timeless aesthetics.
