And another verification of the doxa lie about orange dials. No different than invicta in how they sell shit.
An orange (or bright) dial enhances underwater visibility.
Bright dial colors have become a bit of a calling card for dive watches and we can trace that lasting trend back to 1967 and one brand—Doxa. As legend has it, Urs Eschle, the designer of the now-famous Doxa SUB 300, decided to test a variety of dial colors in murky Lake Neuchâtel and found that orange was best for underwater visibility. But while orange made the Doxa an icon and found its way onto countless other watch dials from Breitling to Seiko, it isn’t the best.
Water absorbs the colors of the light spectrum one at a time as a diver descends. Reds tend to disappear first at a mere 15 feet, followed by orange, and so on.These colors simply turn to a dull grey, unless they are fluorescent, in which case they all glow to great depths. It turns out that the colors that stay visible the longest underwater are yellow and blue, but this is all a moot point because the legibility of a dive watch really has nothing to do with the dial color, but rather the amount of contrast between hands and the dial. And for that, nothing really is better than a black dial with big fat white hands, specifically the minute hand.
