Whether surfing or at an extreme depth of 4,079 meters. We exclusively utilize securely-screwed crowns in order to guarantee that no water can enter the watch case at any time. Ten-minute markers are actual digits, while five-minute positions are more simply marked on the diving bezel. Through an entire rotation, the bezel snaps with minute-precision 120 times securely into place. By comparing the zero position with the minute hand before a dive, the elapsed dive time can easily be determined at a glance. Finally, the unidirectional rotation of the bezel prevents the display of a dive time shorter than the actual dive time in case of accidental bezel movement.
