ABSTRACT:
A digital display for an electronic timepiece having first visual indication display segments peripherally disposed around numerical display digits for selectively indicating predetermined integral time zones corresponding to the time displayed by the numerical display digits and further visual indication display segments for discriminating time zones that are not integrally related to the time zones indicated by the first indication display segments is provided. The display is characterized by a bezel surrounding the plurality of visual indication display segments, the bezel having a plurality of first distinct indicia disposed therearound. Each of the first indicia are disposed proximate to the position of the first visual indication display segments to identify the predetermined global time zone selectively indicated thereby. At least one second indicia is disposed on the bezel intermediate a pair of first indicia. A second visual indication display segment is disposed proximate to each of the second indicia for discriminating between the integral global time zones, indicated by the first indication display segment, and the non-integrally related time zones indicated by the further indication display segments and second indicia disposed proximate thereto.
