Caliber 2790 SQ

Hand-wound, barrel-shaped movement with tourbillon escapement and power reserve indicator; skeletonized. Geometrical shapes have always inspired the greatest builders, architects and artists, playing with light according to the position of the sun or forming a pyramid of chiaroscuro contrasts based on fundamental geometrical elements arranged in layers. Inspired by these works, Vacheron Constantin has devised an original architectural motif based on the shape of a triangle to provide a unique interpretation of hand engraving. Once again demonstrating the impressive range of their art, the artisans of the Manufacture performed truly stunning work on the surface of the parts composing Calibre 2790 SQ. In a succession of meticulous strokes of the burin that sometimes involves working to the nearest tenth of a millimetre, they have created tiny triangles composed of recurrent straight lines creating a three-dimensional effects, before hand-drawing and chamfering the 246 parts of the calibre. This geometrical mosaic forms an architecture generating an astonishing volume effect through light and shadow effects further enhanced by the airy structure of the imposing tourbillon carriage.
