As technical as it is fun, it is water-resistant to 300 meters and beats to the rhythm of a self-winding Chopard movement. Combined with a large 40 mm steel case, the unidirectional rotating bezel with its blue-raspberry coloring is inspired by azure blue shades and brightly colored corals, while featuring a wave-shaped design for easier handling under water. The screw-down crown is marked with a C and the case-back is engraved with a wave motif. The intense blue dial brings to mind the ocean depths and is enhanced with a white minutes hand hemmed with raspberry that glows at night or in dark, deep waters. The hour-markers and hours hands also illuminate with a blue hue, with all other indications required for diving in green. Five moving diamonds, like oxygen bubbles or tiny sparkling fish, swim around this beautiful aquarium.
