Clock machine core with time zone display

This invention is about the clock machine core with time zone display and is composed of the followings: a motive-power generation apparatus; a counting second apparatus; a counting minute apparatus; a counting hour apparatus and a time zone display apparatus. A second hand/disc, a minute hand, and the hour hand are pivot connected with the counting second apparatus, the counting minute apparatus and the counting hour apparatus, respectively. After that, the first landmark of local time zone is aligned with the reference line of case body and the local time is calibrated. Then, time zone adjustment ring of time division display apparatus is turned to the second landmark of one certain time zone to make it align with the reference line such that its inner ring tooth is made to synchronously drive the planet indolent wheel and the planet base wheel to rotate. The hour front wheel exhibits planet motion by following the minute wheel on the planet base wheel so as to make the set of fitted time wheel rotate. The hour hand is made to move such that the time indicated by hour hand represents the time of the second landmark.
