Hours, minutes, seconds, date. This Overseas watch by Vacheron Constantin provides the essential functions of a timepiece. Housed inside a 41-mm case, the new Manufacture calibre delivers a comfortable 60-hour power reserve thanks to twin barrels. A soft iron ring surrounds the calibre to protect it from magnetic disturbances. Water-resistant to 150 metres, this model is delivered with three interchangeable straps, as are all the watches in the 2016 Overseas collection: an adjustable-length steel bracelet, a leather strap and a rubber strap, the latter two fastening with an interchangeable steel folding clasp. This easy-fit system has been developed specifically for the new Overseas models.
