Claim:
A time counting assembly with a display for world time zones, comprising a power source, a second counter, a minute counter, an hour counter, and a time zone display for displaying a correct time over a faceplate; wherein the time zone display further comprises: a time zone adjustable ring rotatably set between a substrate and the faceplate, providing a planetary idle gear set between the substrate and the faceplate to mesh an inner gear ring of said time zone adjustable ring and a planetary base wheel, which is pivoted to a bottom of said substrate, said planetary base wheel allowing a minute wheel set to pass therethrough, said planetary base wheel having a bottom circumferentially pivotally mounted with a front hour wheel of said hour counter, and at least two engaging hooks being separate and individual, each of the at least two engaging hooks has a first end fixedly connected to a bottom of said substrate and a second end selectively engaging one of a plurality of ratchet holes that are arranged on the periphery of a top side of said time zone adjustable ring; whereby stir said time zone adjustable ring with the hand to align a first landmark of a local time zone with a fixed point and then calibrate the time counting assembly in accordance with the local time, and then stir said time zone adjustable ring with the hand to align a second landmark of another locating time zone with said fixed point such that said inner gear ring moves said planetary idle gear set and said planetary base wheel to shift engagement of said engaging hooks in said ratchet holes, and said front hour wheel is rotated on said planetary base wheel with a planetary movement along said minute wheel set to cause rotation of a meshed hour wheel so as to turn a hour hand to the time in accordance with the time zone corresponding to said second landmark.
