We tested 30 automatic watches to find the best ones for every wrist and budget. Powered by the energy of your own body, automatic watches provide a mechanical beauty in our digital world.
Video of the rotor turning in an automatic wristwatch having a glass back, when the watch is moved by hand. An automatic watch, also known as a self-winding watch or simply an automatic, is a mechanical watch where the natural motion of the wearer provides energy to wind the mainspring, making manual winding unnecessary if worn enough.

Whereas a mechanically-wound watch must be wound with the pendant or a levered setting, an automatic watch does not need to be wound by the pendant; simply rotating the watch winds the watch automatically. The interior of an automatic watch houses a swiveling metal or brass "plate" that swivels on its axis when the watch is shaken horizontally ...
[citation needed] An automatic timepiece needs to be worn for about 10–15 hours before it is fully wound. [citation needed] The power reserve indicator displayed on the watch with automatic- winding movement shows how long a watch will function when not worn. On a manual winding watch, it shows the time left until the watch needs winding.
Single watch winders are good for anyone with one or two automatic watches that they wear regularly, or if you use an auto mixed in with a couple quartz watches. Single watch winders don't take up ...
It is also possible for quartz clocks and watches to have their quartz crystal oscillate at a higher frequency than 32 768 (= 2 15) Hz (high frequency quartz movements [4]) and/or generate digital pulses more than once per second, to drive a stepping motor powered second hand at a higher power of 2 than once every second, [5] but the electric ...
The first self-winding mechanism was invented for pocket watches in 1770 by Abraham-Louis Perrelet, [57] but the first "self-winding", or "automatic", wristwatch was the invention of a British watch repairer named John Harwood in 1923. This type of watch winds itself without requiring any special action by the wearer.
Watch movements require regular cleaning and lubrication, and the normal result of neglecting to get a watch cleaned is a watch stopped at full wind. As the watch movement collects dirt and the oil dries up, friction increases, so that the mainspring doesn't have the force to turn the watch at the end of its normal running period, and it stops ...
