Nixon The 51-30 Tide Blue Sunray Men´s Watch

If you consider that divers rely on a good watch in order not to die, one could expect designated divers watches to be quite robust timepieces. In Germany, where we are based, a divers watch has to fulfill certain criteria before being allowed to be called a divers watch. These watches are usually watertight to a pressure of 20 bar and over. They are also fitted with large indexes and fingers so that they are easy to read through your goggles in the dim light of the deep blue sea at a distance of at least 25 cm. They will also have to have a timer or a bezel which can be turned to indicate the time a diver needs to consider when calculating the remaining oxygen in his or her tank and to keep the intervals needed when ascending back to the surface. This bezel can only be turned one way so as to eliminate the possibility of it being moved by accident, increasing the diving time over the oxygen supply and thus causing a horrible death through drowning.
