Winner of the GPHG 2019 Innovation Prize, the Traditionnelle Twin Beat Perpetual Calendar is now being unveiled in 2026, reflecting Vacheron Constantin's constant quest for innovation. Its 950 platinum case, an alliance of tradition and modernity, encases a multi-layer dial. Enhanced by hand-guilloché and offering optimized readability through an adjusted transparent sapphire and a laser-frosted disc, this watch presents a refined aesthetic. At the heart of this horological feat beats the Caliber 3610 QP, equipped with the patented Twin Beat® system. This revolutionary mechanism offers a dual-frequency choice: an Active mode (5Hz/4-day PR), for daily precision, or a Standby mode (1.2Hz) extending the power reserve to a remarkable 70 days, 5 days more than the previous edition. This exceptional autonomy ensures the instantaneous perpetual calendar remains accurate for over two months unworn. The ensemble is elegantly complemented by a new textured strap.
