ABSTRACT:
Briefly stated, the invention is practiced by providing a wristwatch with a case having manually actuated switches, a microcomputer in the case responsive to the switches, an annunciator responsive to the microcomputer, and an electrooptic display having a set of first segments arranged to provide digits and a set of second circumferentially spaced radial segments surrounding the first segments. The microcomputer is programmed to provide several modes of operation, such as a time of day mode, a timer mode, a chronograph mode, and a ratio calculation mode. The time of day mode is arranged to display local time of day on the first segments and time in another time zone on the second segments. The timer mode is arranged to display the time remaining in a countdown time period selected by manually actuating one of the switches. The time remaining is displayed on the first segments while local time of day is displayed on the second segments. The timer mode is further arranged in the last stage of the countdown time period to stop displaying time of day on the second segments and to initiate a sequential cumulative actuation of the second segments in a prescribed pattern which indicates imminent start of the race.
