WHAT IS AN AUTOMATIC MOVEMENT?
An automatic movement is a mechanical watch movement that operates by the continuous motion of the wearer’s wrist. The rotor, a half-disc metal weight, pivots freely around a spindle, and a movement in either direction helps to rewind the mainspring. Automatic watches don't need to be wound if worn every day. The watch is regulated by a spiral balance wheel that vibrates 6-8 times per second. An automatic movement is composed of more than 70 parts and up to 230 parts for the Calibre 360. While it is slightly less precise than a quartz movement (by a few minutes per month), it is the ultimate example of Swiss watchmaking expertise and tradition.
TAG HEUER AUTOMATIC MOVEMENTS
All TAG Heuer automatic movements are made in Switzerland and must meet extremely strict criteria for precision before they make it onto your wrist. Their high frequency ensures excellent mechanical precision. A number of TAG Heuer automatic movements are awarded an Official Swiss Chronometer Control (C.O.S.C.) Certificate, the ultimate recognition of precision and reliability.
We know you don’t like to take time out to recharge, so we made sure your watch can keep up. TAG Heuer automatic movements have a power reserve of about 42–48 hours, depending on the model. This means that when they are fully wound they can continue to operate for almost two days and nights without being worn. You can also rewind the mainspring manually by unscrewing the crown and pulling it out gently to position 1. Note: do not forget to screw the crown down again in position 0.
Our watches are designed to operate continuously, but an automatic watch movement does require regular maintenance to keep it in mint condition. With proper care, it will work perfectly and last for generations. TAG Heuer recommends a maintenance service every two years in addition to an annual water-resistance checkup. All watches maintainted by an official TAG Heuer service center have a one-year extension warranty.
