Abstract

A wall clock has a first time increment portion comprising a stationary frame member. A timepiece movement is supported by the stationary frame member. A first wheel is rotatably driven by the timepiece movement, and a first time indicating member is rotatably driven by the timepiece movement for indicating a first time increment (i.e., hours). A belt is disposed around and driven by the first wheel. A second time increment portion rotatably supports a second wheel. The second wheel is rotatably driven by and suspended only by the belt, so that the second time increment portion is suspended only by the belt. A second time indicating member is rotatably driven by the second wheel for indicating a second time increment (i.e., minutes). The diameters of the first wheel and second wheel have a ratio of 12:1 so that the single timepiece movement can drive both the hour time indicating member (hour hand) and the minute time indicating member (minute hand) at appropriate speeds, through a simple and easy to manufacture construction.
