Answer
When your heart pumps, it sends a surge of blood through your body. And, these pulses cause your arteries to expand and contract as the blood surges through. The wrist is a good place to take a heart rate measurement, because the arteries running through it have a definite pulse with each heart beat (that's why they measure your pulse at your wrist).
With each surge of blood, the electrical conductivity of your wrist changes slightly. Or, maybe the capacitance you exhibit between a pair of electrodes changes. But, the electronic circuits in the watch detect these changes in electrical characteristics and count them over time. This is then extrapolated out over a minute and the resulting signal causes a certain number to be displayed on the screen. This is your heart rate.
