Abstract: A runners watch which includes a lightweight case dimensioned to be worn on the wrist of the wearer. A display face is formed on the case. Clock circuitry is disposed within the case for operating the display face in order to display the time of the day, the date and elapsed time to the wearer. A sensor in the case detects the stride of the wearer when the wearer is running or jogging. Circuitry within the case is responsive to the sensor for computing the distance traveled by the wearer. Circuitry within the case is also responsive to the sensor for computing the rate of travel by the wearer. Switches are provided on the case for being operated to display the computed distance and the computed rate of travel.
