发明名称 Timekeeping display
摘要 A timekeeping display of the type in which a set of hands rotate about an origin and sweep across a face to indicate the time in an analog fashion, wherein the face is divided into a plurality of part-faces each of which retains its spatial relationship to the origin, and which are separated from each other to divide the origin into that plurality of notional origins; and in use, the set of hands appear to rotate about each notional origin and each hand sweeps across each part-face in every revolution.
