How automatic watches work
Automatic Watches are watches that do not need winding, you may not remember but not that long ago watches needed to be wound each day if it was to continue to work. An automatic watch has the same mechanism as the old winding watches but it now powers itself.
An automatic watch doesn't need a battery, it is powered by your own movements. When you move your arm or wrist the rotator in the watch rotates and winds the mainspring to enable the watch to continue working. Its an incredible design which now ensures that your watch will continue to work without battery or winding.
These self winding watches work best for people who wear their watches frequently, if you don't wear your watch every day you will need to manually wind it to compensate for the lack of movement felt by the watch. An automatic watch depends on your arm movement to be able to keep functioning.
The power reserve of such a watch can go up to 3 days without running out of power, you can build up your reserve by continually wearing your watch and providing enough movement to keep it functioning.
Rolex was the first brand to use this ground breaking new watch design, which they still use. All the other major watch brands have now followed suit and are making automatic watches. These watches differ from Quartz watches whose power source is from batteries, the automatic watch will never run out of battery as it only needs to be worn to work.
Automatic watches now come in a variety of designs, you can of course purchase designer watches, led watches and quart watches depending on your own preferences.
