The BVL 360 caliber is an automatic manufacture movement featuring an Annual Calendar function with a 225° Date Rétrograde hand.

This “haut de gamme” movement is distinguished by handmade finishings in keeping with the highest standards of Swiss watchmaking know-how. The plate and the bridges are hand-decorated with two different perlages, an original biaxial “côtes de Genève” and a “traits tirés” treatment. All the edges of the plate and bridges are “diamantés”, as are the sinks around the jewels. The peerless craftsmanship of the “finisseurs” can be seen in even the smallest components, such as the polished and chamfered screw heads. The 18-ct gold oscillating weight segment is finished with a “satiné circulaire” treatment, while the central “colimaçonnée” part of the rotor features a unique shape that repeats the dial design and reveals the movement and the redesigned bridges within.
