Official description

A new interpretation of the Overseas ultra-thin perpetual calendar model joins the collection. Both contemporary and eminently horological by nature, this gold-clad piece is magnified by a sapphire dial extending an invitation to dive into the heart of its anatomy and explore its ultra-thin entirely openworked perpetual calendar Calibre 1120 QPSQ/1.

Ultra-thin watches are part of the grand watchmaking tradition of the Maison. They have always been considered the ultimate quest in a mechanical world where extreme thinness is a symbol of style and elegance. The exceptional slenderness of the case, the meticulous attention to detail, the bold aesthetic choices – this age-old quest inherent to Vacheron Constantin reveals the anatomy of beauty characterising Vacheron Constantin watches. As early as the 1930s, the Maison distinguished itself with ultra-thin pocket watches, then in the 1950s with wristwatches that were among the thinnest of their generation. In 2016, the Overseas collection stood out by offering a new aesthetic signature and unprecedented calibres and extreme thinness was naturally part of the adventure, resulting in an ultra-thin Overseas perpetual calendar watch.
