The new blue face revitalizes the Patek Philippe tradition of grand feu enamel dials, providing the Ref. 5370 Split-Seconds Chronograph with a highly contemporary touch. Its displays are eminently legible as befits a technical instrument. The fascinating movement stands out with a classic architecture, featuring trailblazing innovations and a redesigned rattrapante mechanism. The elegant platinum case is graced with a concave bezel and flanks with satin-finished recesses.
