ALL MOVEMENTS

Just like an engine powers a car, a watch movement, also known as a “calibre” is the internal mechanism that makes a watch work. Think of it as the heart of the watch, pumping energy into all of the watch’s functions from its hands to its chronographs to make everything work in harmony. While a polished exterior is a must for any quality timepiece, it’s what’s on the inside that really counts.

AUTOMATIC MOVEMENT mobile_title_border

An automatic movement is a mechanical watch movement that operates by the continuous motion of the wearer’s wrist.

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.

POWER RESERVE
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.

WATCH CARE
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.

BELT-DRIVEN MOVEMENT mobile_title_border

The patented belt-driven transmission is a high-yield relay of 5 notched micro drive-belts whose tension is controlled by 2 turnbuckles

ELECTRO-MECHANICAL MOVEMENT mobile_title_border

The Calibre S proposes a new method of measuring and reading time by means of bidirectional systems that are mechanically independent but synchronized

ISOGRAPH TECHNOLOGY mobile_title_border

With its revolutionary carbon composite hairspring, the ISOGRAPH technology becomes the heart of the movement and provides a cutting-edge chronometric precision.

A NEW SPIRAL FOR A MAJOR INNOVATION

Always at the avant-garde, TAG Heuer unveils in 2019 a new type of hairspring, built with carbon composite. Previously made of metal, Elinvar or Silicium, the hairspring is a small spring attached to the balance wheel to form the regulating organ of the watch. Therefore, it also guarantees its precision. Patented by TAG Heuer, the hairspring is an extremely difficult element to produce and assemble. However, it nearly adapts to all movements and regulating organs with the same efficiency. Requiring the manual intervention of 4 watchmakers, the ISOGRAPH technology has been integrated into the Heuer 02 Tourbillon house movement, combining two extraordinary elements. TAG Heuer thus confirms the full extent of its savoir-faire.

 

UNMATCHED CHRONOMETRIC PRECISION

Key element in the operation and precision of a watch, the hairspring is also essential in terms of time measure. An area in which the ISOGRAPH technology offers very high performances, thanks to a custom-made balance wheel and a carbon composite hairspring more resistant than ever. Models featuring the ISOGRAPH technology are all certified chronometer by the COSC.

 

CARBON: THE IDEAL MATERIAL

Chosen by the TAG Heuer institute to manufacture its new hairspring, carbon has replaced metal, Elinvar and Silicium. Lightweight, shock resistance, stability, anti-magnetism, optimal thermal behavior: its numerous advantages provide unique performance and improved accuracy.
