Inspired by the crown protection designed by Jean-René Parmentier in 1962 (see page ”HERITAGE”), we have named this model the “Subphotique” because it can withstand depths of 500 meters (1640 Ft), far below the ocean’s photic zone (about 200 meters/656 Ft below the ocean’s surface), and where light is entirely absent. True to the original Triton, the “Sport” dials have hand-painted lume plots.
