During the day, Oktopus Blue Sea is clean and monochromatic, with a subtle dial and clean facets on the milky white case. In darkness however, when the lights go down, the piece reveals its new personality, and features three different colors – aqua blue, ultramarine blue, and finally a new violet lume are used to create a stunning visual effect.

These three shades of blue become progressively darker as you go down deeper into the watch, as if you are looking off the edge of a boat into deepening water in a reef.

On night dives, the Oktopus blue Sea glows like a searchlight and is waterproof to depths of 300 metres. The blue spectrum of emitted (glow) light is very good for very dark environments as in total darkness, your eye sees the blue spectrum better, as the eye shifts from photopic to scotopic.

This is the first time an ALW case, an aerospace metal developed to achieve the ultimate weight reduction and strength, has been combined with a Double Date Dubois-Depraz movement in a LW Piece. The case is twice as hard as steel but extremely light weight – and is half the weight of our titanium cases.
