On these two models, rubber has been blended with ceramic to create unique bezels which highlight the first 15 minutes. Why red and blue? Dive to 5 m and red is the first colour to disappear, blending stealthily with a diving suit. Go deeper to 275 m and the last colour you’ll see is blue. Finally, at a depth of 300 m, everything goes black, except of course, your still highly-visible Planet Ocean divers' watch with Super-Luminova.
