Vacheron Constantin has unveiled a new evolution of its Traditionnelle Twin Beat Perpetual Calendar, further advancing one of modern watchmaking’s most technically ambitious complications.
The latest model increases its remarkable power reserve from 65 to 70 days thanks to refinements made to the hand-wound Calibre 3610 QP. At the heart of the watch is the Maison’s patented Twin Beat system, which allows the movement to switch between a high-frequency 5Hz Active mode for daily wear and a low-frequency 1.2Hz Standby mode when not in use, preserving energy without sacrificing accuracy.
The perpetual calendar mechanism has also been optimised through a newly engineered low-energy instant-jump system, contributing to the extended reserve.
Housed in a 42mm platinum case, the watch features a contemporary openworked aesthetic. A transparent sapphire dial reveals the movement beneath a slate-grey hand-guilloché gold surface, highlighting the complexity of the calibre. Finished with a black textured calfskin strap, the Traditionnelle Twin Beat Perpetual Calendar combines cutting-edge innovation with the refined craftsmanship synonymous with Vacheron Constantin.
