Abstract
A combined watch, elapsed time counter and pulse rate meter which is totally portable and worn as an ordinary wristwatch. The timer and pulse rate meter employ the precise timing elements such as a crystal oscillator of the digital watch. Using such precise timing elements, the human's pulse may be measured on a pulse by pulse basis and the instantaneous and average pulse values simultaneously displayed to allow a running comparison and noting of pulse aberrations. A novel pulse detector assembly is located on the inner face of the watch assembly.
