A new frontier in watchmaking by TAG Heuer

WHAT IS ISOGRAPH TECHNOLOGY AND WHY IT’S SO REVOLUTIONARY THAT IT’S BECOME A WATCHMAKING FIRST?

 

 

Isograph technology explained
Magnetism, shock and gravity have virtually no effect on TAG Heuer’s revolutionary new oscillator, which features a tailor-made balance wheel and a hairspring made of a new material developed in-house by the innovative Swiss watchmaker.
KEY BENEFITS OF TAG Heuer’s ISOGRAPH TECHNOLOGY:

  • The lightweight hairspring is virtually unaffected by gravity and shock due to its high strength-to-density ratio and its purely elastic behaviour.

 

  • The carbon-composite hairspring is completely antimagnetic,which eliminates the issue of inaccuracy after a watch comes into contact with a magnetic source.

 

  • Resistance to temperature fluctuations has been achieved by pairing the carbon-composite hairspring with a tailor-made balance wheel.

 

  • Accuracy is improved thanks to perfect concentric oscillations as a result of the carbon-composite hairspring’s design.
  • This accuracy is maintained no matter how the watch is worn, held or stored. Typically, a watch’s timekeeping performance will be affected by whether it is held horizontally or vertically. Due to its low density, the carbon-composite hairspring can significantly improve this phenomenon.

 

  • The carbon-composite hairspring is produced with the collet already attached; usually, this small part, which attaches the metallic hairspring to the balance wheel axis, requires complicated assembly and increases the risk of further inaccuracy.
During the Geneva watch fair earlier this year, TAG Heuer unveiled an innovation – one that demonstrated its commitment to developing technology that explores uncharted realms of watchmaking. The new technology, called Isograph, is an oscillatory regulator with a carbon-composite hairspring and tailor-made balance wheel that improves accuracy and timekeeping performance, particularly with regard to environmental interference. The technology is integrated into the TAG Heuer Carrera Calibre Heuer 02T Tourbillon Nanograph and the new TAG Heuer Autavia collection, and will be found in more TAG Heuer watches in the future.

 

Born of the necessity to overcome the challenges posed to metal and silicon hairsprings – shock, magnetism and gravity – TAG Heuer’s Isograph technology is produced through a highly innovative manufacturing process developed in-house by the TAG Heuer Institute. The oscillatory regulator uses a carbon-composite hairspring, a completely new material created by the Institute, and a tailor-made balance wheel.

Together, the carbon-composite hairspring and tailor-made balance wheel form the oscillatory regulator. This technology has been given the name Isograph – the trademarked name comes from the Greek words iso, meaning “equal”, and grapho, which means “to write”, referring to the stable and consistent movement of the component.

Known as the heart of the mechanical watch, the hairspring is the most difficult part to produce as its minute tolerances directly impact the overall accuracy of a timepiece. A team of TAG Heuer mathematicians, physicists and chemists are behind the creation of this reinvented hairspring. Usually, just a small proportion of Swiss watches are certified as chronometers. In the case of the new material that TAG Heuer has developed specifically for the hairspring, 100% of the production material is of certifiable quality, which is a clear advantage over conventional hairsprings.

 

Reflecting TAG Heuer’s legacy of avant-garde watchmaking, Isograph technology is a revolution in horology. In the future, it will be found in timepieces across the brand’s collections for men and women. Harnessing the innovative power of the TAG Heuer Institute, the unconventional Swiss watchmaker will continue to pursue advancements that improve the performance of the stylish mechanical watches that bear the iconic TAG Heuer shield on their dials.
