Polished silver hands and baton hour markers blend naturally into the open-worked structure, reinforcing the watch’s futuristic appearance. The transparent tonneau-shaped case allows light to pass through multiple angles of the movement, creating a striking three-dimensional mechanical display on the wrist. Adding further luxury presence, the diamond-set bezel frames the exposed dial with brilliant reflections, while the deep blue rubber strap introduces sporty contrast against the transparent architecture.
