Harry Winston have created the Ocean Triple Retrograde Chronograph, a complex yet elegant watch. The dial features three separate retrograde counters that mark the seconds, minutes, and hours. The self-winding mechanical movement enables the three hands to fly back to their starting position so interval timing may continue. This sophisticated timepiece, which has forty hours of power reserve, is available in either the Diamond Like Carbon with five different dial finishes or in eighteen karat white or rose gold with four different finishes.
