ABSTRACT:
A time equipment with time zone mechanism includes a 24-hour dial, an hour hand and a minute hand mounted for rotating above said dial, a movement for driving said hour hand and minute hand to rotate one revolution per 24 hours, a time zone mechanism, and a setting mechanism for said time zone mechanism. The time zone mechanism comprises a time zone disc coaxially mounted under the dial and a driving device for driving the time zone disc to rotate one revolution per 24 hours. The time zone disc has an outer time zone ring portion disposed around the periphery of the dial and provided until a plurality of time zone city indicators arranged in the same order as the time zones. The setting mechanism is adapted to drive the time zone disc to rotate independently with one of the time zone city indicators representing a desired city of the time zones aligned with the hour hand, so that the current time of other time zone cities provided on the time zone disc can be read simultaneously coincident with the corresponding hour numerals inscribed on the dial respectively.
