The first striking new feature of the DAVOSA Apnea Diver Automatic is the multi-colored ring around the dial. It sports the French national colors only by chance. In fact the colors blue, white and red replicate an internationally recognized breathing exercise in freediving: A breath is taken during the five-second blue phase, it is held for 15 seconds (white area) and then air is expelled over 10 seconds (red area). With the help of this color code, the freediver can concentrate fully on this vital breathing exercise without needing to count or use a stopwatch.
