Vacheron & Constantin One of the recognised ‘Holy Trinity’ of Swiss watchmaking along with Patek Philippe and Audemars Piguet, Vacheron & Constantin is also the world’s oldest ‘Watch Manufacture’, and as such, it has remained in continuous operation since 1755. More than this, Vacheron & Constantin is the founding father of a spirit of technical excellence taken so far, it is considered an art. This is known as ‘Haute Horlogerie’ in which Vacheron & Constantin has been the for over 260 years. This tradition defines the Manufacture, evident in the finest quality execution, reflected in a finish which goes far beyond the demands of the ‘Poinçon de Genève’. Created in 1886 the ‘Seal of the State of Geneva’ is the highest accolade, reserved for only the very finest quality watchmaking.
