With the S6000 Manta Limited Edition, Oceanus created a blue frameless, one-piece sapphire crystal bezel, achieved using a special spiral-cutting production technique, and by applying a blue graduated ion-plating/vapor deposition treatment to the underside of the bezel, which creates a range of blue hues that match the blue gradient dial.

Made from a synthetic sapphire crystal material, with a polygonal shape on the sides, and a wave pattern on the top, there are cuts on 48 sides in total, with each facet perfectly polished to a jewel finish — resulting in a gorgeous sparkle effect created by every ray of light that hits the surfaces on both the horizontal and vertical axes of the bezel.
