ABSTRACT:
An electronic timepiece including a global time display that is adapted to display local time when the timepiece is in a local time mode and is adapted to be automatically indexed to display a time at a different time zone when the timepiece is in a global display mode is provided. A plurality of numerical display digits are provided for displaying time information and a plurality of visual indication display segments are disposed about the numerical display digits for selectively indicating a predetermined time zone corresponding to the time displayed by the numerical display digits. The mode select circuitry is provided for effecting a display of local time by the display digits and a local time zone by the visual indication display segments when the selection circuitry is disposed in a global time mode. Indexing circuitry is provided for indexing the count of the numerical display digits and for indexing the visual display segments to represent different global time zones representative of the count of the numerical display digits when the selection circuitry is disposed in a global time mode.
