The movement represents an evolution of the iconic caliber that made history in 1969 as the pioneering chronograph combining self-winding mechanics with integrated functionality. This landmark timepiece also earned distinction as the inaugural mechanical chronograph operating at 5 Hz frequency—translating to 36,000 oscillations per hour—thereby delivering precision measurements to 1/10 second increments. Contemporary engineering meets horological heritage within this fully see-through movement architecture, now incorporating a cutting-edge silicon escapement that delivers state-of-the-art dependability, accuracy, and consistent performance.

Material innovation stands as a cornerstone of this manufacture's philosophy, spanning from the earliest applications of elastomer compounds in horology through to the engineering of proprietary hard-wearing alloys and the pioneering of revolutionary substrates including ceramic and sapphire available in distinctive finishes. The realization of these exceptional materials stems from the Manufacture's dedicated materials science and metallurgical center, which collaborates seamlessly with internal R&D teams and dedicated casting workshops. These proprietary compositions undergo refinement and fabrication via specialized techniques and processes that represent the pinnacle of horological craftsmanship—methodologies held within the brand's exclusive domain.
