If there is one art that few watchmakers truly master, it is that of striking mechanisms, the horological complications acknowledged to be the hardest of all to produce. The Manufacture Vacheron Constantin has been creating such miniature marvels for over two centuries, and is now laying a new milestone with the Patrimony Contemporaine Ultra-Thin Calibre 1731, bearing the prestigious Hallmark of Geneva. This masterpiece of virtuosity combines the complexity of a striking mechanism with the additional challenge of producing the thinnest minute repeater calibre and the thinnest minute repeater watch on the market. At just 3.90 and 8.09 mm thin respectively, both the movement and the timepiece housing it are dedicated to the most accomplished expression of the watchmaking art.
