ABSTRACT:
A structural improvement for the global timepiece principally makes use of an hour wheel which engages and drives a post hour wheel and thereto engages and drives a city wheel through a post hour pinion which is on the same shaft as the post hour wheel, and sequentially lock-to-fit to rotate the city wheel and the city dial through the lock jumper, thereby makes the face become an outer ring which is a stationary time ring, a center ring which is a otationally adjustable city dial and an inner ring which is a dial indicating the local time; in this way and through the simple judgement, one is able to read simultaneously, from the same timepiece's face, the time of each time zone's city all over the world, also as far as time adjustment as concern, one can use the hour wheel or city dial or both to adjust the time inquired. Besides, the face design of the present invention can read clearly and easily the date everywhere through the indication of the international dateline. This is an original work with practical and progressive features.
