TIMEPIECE
Document Type and Number:
WIPO Patent Application WO/2000/054114
Kind Code:
A1
Abstract:
A timepiece comprises an hour hand which turns with the rotation of the earth synchronously so that it turns a circuit during day and night. This makes people to have some feeling about time-space. Specially, a dial of the timepiece is provided with a disk-like hour hand on which there is indicated the time zone line about 24 time zones on the earth. Both disk-like and pointer-like hour hands turn synchronously. It is convenient to read the time at start and end places of travel which is across time zones at the same moment and read the difference of time between two places. The timepiece can be implemented easily. It needs to ensure the transmission ratio between hour wheel and minute wheel to be 1:24.
