Abstract
A digital watch having a face mounted detachable pulse sensor unit coupled to infrared plethysmograph electronics within the watch. The pulse sensor unit is detachable from a receptacle on the watch face and mountable into a receptacle at a first end of a remote pulse sensing cable. The second end of the cable is connected into the watch receptacle for conveying the pulse sensing information to the infrared electronics. A cuff holds the pulse sensor unit in place against the wearer'"'"'s finger for sampling his heartbeat. The wearer may thus monitor his pulse rate while both hands are free.
