In 1954, in collaboration with Pan Am Airways, Rolex developed the first dual-time watch, the GMT Master, which had the incredibly useful function for the airlines personnel of being able to tell the time in two separate time zones simultaneously. Since then many luxury watch brands have designed their own versions of this watch & now we have given the iconic design a Christopher Ward make-over using the stunning ETA 2893-2 automatic movement as the power source. & because the Trident has a uni-directional bezel it is possible to know the time in three time-zones simultaneously.
