The present example is part of a limited edition series of 260 pieces made to commemorate the 260th anniversary of Vacheron Constantin. Housed in a beautiful oversized cushion-shaped case, the dial reflects the traditional approach on horology and the rich history of the company thanks to details such as the use of "Breguet-like" numerals and the pulsometer scale. Furthermore, it is a single-button chronograph, typical of the earliest days of the past century.
