Same as some of the best and most expensive watches in the world these watches are completely mechanical and made up of many tiny precision engineered parts. Often referred to as “self-winding”, automatic movements harness energy through the natural motion of the wearer’s active wrist. As long as the watch is worn regularly, it will maintain power without requiring winding. Seiko made their first automatic in 1895. Some models have movements than can also be hand wound from the crown, this is useful if you don’t wear the watch every day. Automatic watches beat very fast and have the “sweeping” seconds hand rather than “ticking” hand of a quartz watch.
