Description With the Commander Gradient Swiss watch, watchmaking mechanics become visible thanks to a transparent acrylic dial - a first in this iconic collection. The components of the Caliber 80 can be admired on the dial side as well as on the rear thanks to a transparent case back. Adorned with an original gradated smoky effect, the dial becomes increasingly opaque around the edges while the date at 3 o'clock stands out perfectly.
