Abstract:
A clock movement with a display for world time zones comprises a power source (1), a second counter (2), a minute counter (3), an hour counter (4), and a time zone display (5). The time zone display (5) further comprises an intermediate base (55), a time zone adjustable ring (51), and a dial plate (52). The intermediate base (55) provides a planetary basic gear (56,57) axially attached to the central of the bottom thereof to be passed through by a minute wheel set. The planetary basic gear (56,57) at a lower side thereof connects with both an axial stem (411) provided with a front hour wheel (41) and a join ring (58) at a lower periphery thereof. The join ring at a periphery thereof extends at least two circumferential elastic engaging hooks (582). The time zone adjustable ring (51) provides an inner gear ring part (513) to mesh with the planetary idle gear (53) having an angle hole (531) engaging with a corresponding angle projection (571) provided in the planetary driven gear (57). The planetary idle gear (53) is rotatable on the dial plate (52) which is inserted into the time zone adjustable ring (51). An inner ratchet ring (514) with a plurality of ratchet teeth at the top of the time zone adjustable ring (51) engages with the two engaging hooks (582). Hence, the dial plate (52) can display a correct time.
