A resettable interval timer in combination with, but functioning independently from a digital watch which provides horological information. The watch operates in two modes; the first mode displaying horological information on the display devices and the second or stopwatch mode displaying interval timing information on the display devices. In the watch mode the user can program which horological information he desires to be continuously displayed on the display devices, either hours, minutes, and seconds, or hours, minutes, and date. By depressing one of the watch push buttons the user can momentarily display month, date, and the A.M. or P.M. horological information on the display devices. A predetermined push button depression sequence can be used to reset the horological information. When a second push button is depressed a predetermined number of times within a defined time interval the watch enters the stopwatch mode. In the stopwatch mode the user can reset the interval timing counters to zero, start the interval timer, stop the interval timer, freeze the interval timing information currently on the display devices (split or lap time), return the counters to the interval timing mode, and finally return the watch to the watch mode. |
