The Heart of Precision
Pioneering movements deserve to stand out in inspired and unprecedented designs to truly highlight their ingenuity. The new CHRONOMASTER Open exposes the beating heart of its El Primero 1/10th of a second chronograph calibre in a novel and unexpected way, while retaining the signature tricolour counters dial configuration. It reveals the high-frequency beating heart of the watch, with the escape wheel and pallet lever crafted in lubricant-free silicon.
