PURPOSE: To obtain a clock easy to operate and learn operation, highly practical and excellent in design by a method wherein a small alarm clock is independent of a basic clock and alarm time and normal time are corrected with a button and winding stem.
CONSTITUTION: A step motor 3 is located distant from hour and minute pointers indicating normal time, which are located at the center of the clock body, and off from the center to drive a small second pointer for indicating normal time second. A step motor 15 drives a chronograph second pointer located over the hour and minute pointers at the center of the clock body. A step motor 27 drives a chronograph minute pointer located off the center of the clock body. A step motor 32 drives alarm hour and minute pointers fro indicating the alarm time located off the center of the clock body. A small clock made of the alarm hour and minute pointers has a time change function whereby the alarm time and normal time can be selected. By reversely driving the step motors 15, 27, the minute and second of a time can be displayed by the same pointers as the chronograph pointers, respectively.
