Abstract: An improved clock movement power transmission union is disclosed for saving space and providing flexibility of design options. It comprises: (a) a casing having main input and main output holes, wherein the main input and main output holes are disposed such that their fictitious axes intersect at a specific angle; (b) a main input shaft and a main output shaft received by the main input hole and the main output hole for rotating about their individual fictitious axes, respectively, so as to drive the hour, minute, and second hands independently. The main input shaft comprises a plurality of input shafts all rotatable about a common fictitious axis, and the main output shaft comprises an equal number of input shafts engageable with corresponding input shafts via a group of drive gear-driven gear combinations, respectively. With this design, the plurality of output shafts can receive rotational powers from the input shafts, respectively and independently of each other.

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.
