Ultraleggero is the most innovative watch in the Nereide series. It draws inspiration from the Vitruvian Man, symbolizing the Renaissance and the close connection between art and science. The peculiar shape of the skeletonized dial fits perfectly with the body of the movement, through an original patented system that guarantees greater lightness and less bulk.
