Quartz - Battery life has an average of 1-2 years. Watch does not require winding and is very accurate.

Solar-Powered watches - watches with panels that capture light and convert it to electricity to power the quartz movement

Kinetic/Auto quartz watches - the weighted rotor, activated by the movement of your arm, turn a mini-generator to generate electricity, which is stored in the watch battery.

Mechanical watches - required daily winding. Experience has shown that this becomes second nature, usually wound in the morning as you start your day.

Automatic watches - also known as self-winding, have a rotor, which is activated by movement of your arm winding the main spring. Can also be hand wound. For those who wish to keep the watch running when not being worn, winding boxes are available.
