The Beauty Of Technical Power Tag Heuer’s First Springless Escapement

TAG Heuer, the pioneer of Swiss watchmaking, has written many important historical articles in the mechanical watch industry for 150 years-from the patented swing gear of 1887 to the innovation of the Calibre360 chronograph in 1/100 second in 2005 table.
Advanced technology draws an important truth: TAG Heuer does not innovate for innovation. Pioneering brand enthusiasm is the driving force behind its true DNA and heritage, as well as its research and development strategy.

三个 The third millennium’s R & D goals: innovation in power, transmission and fine-tuning
Like most machines, a mechanical watch movement contains four basic processes: generating power, storing power, transmitting, and fine-tuning. For centuries, these invariable laws of mechanical watchmaking have been implemented based on three types of complementary blocks: using a barrel as a power reserve system, various gear combinations as a transmission system, and balance wheels, spiral springs, and escapements Composition of the fine-tuning system.
TAG Heuer Monaco V4 concept watch, TAG Heuer replaces the traditional gear combination drive with mechanical transmission belt. In 2004, the concept watch won at the BaselWorld Watch Fair, officially launched 150 Monaco V4 ‘advanced watches’ limited edition in late 2009.
On the occasion of celebrating the 150th anniversary, TAG Heuer launched the TAG Heuer pendulum concept, the first mechanical escapement without clockwork.

TAG Heuer Pendulum Concept
Pendulum concept: ‘invisible’ power generated by magnets
I have been Christian since 1675. Since Christiaan Huygens was inspired by the clockwork invented by Galileo, all the fine-tuning functions of mechanical watches have adopted the balance wheel and spiral clockwork system. Precision alloy spiral belt, through the mainspring to provide the necessary torque swing of the balance to fine-tune the frequency. Over the centuries, many amendments have been made. The son of a Swiss watchmaker, Charlie Edward. Guillaume (Charles-Edouard Guillaume 1861-1938), invented iron-nickel alloys (Invar and Elinvar) with extremely low thermal expansion coefficients. Guillaume was awarded the Nobel Prize in Physics in 1920.
Because the alloy invented by Guillaume reduced the temperature, the spiral spring fine-tuning system has become the mainstream of the mechanical design of clockwork. However, mechanical clockwork still needs to face three major limitations: the gravity destroys its geometric properties due to its mass; the material is affected by thermal expansion; and the difference between the geometric center and the center of mass. These factors that cause time errors can be improved through technology and physical properties, but they cannot be completely avoided.

Magnets generate ‘invisible’ power
克服 In order to overcome the fundamental design bottleneck of the traditional fine-tuning system, cancelling the spiral spring became the first self-challenge faced by TAG Heuer. The second challenge is to still use 100% of the mechanical movement: the movement of the wisdom accumulated by traditional watchmaking, if there is no spiral spring as a fine-tuning, there must be another impetus.
In the TAG Heuer pendulum concept, traditionally used springs are replaced by ‘invisible’ or virtual spring wires produced by magnets. The entire set of devices forms a resonator. The magnetic field is composed of four high-performance magnets, and three-dimensional control is formed by precise geometric operations, thereby generating the linear reaction torque necessary for oscillation of the balance wheel. The oscillating period of the TAG Heuer pendulum concept can resist changes from external forces, which is also the primary condition for an excellent timer. The movement of this revolutionary oscillator is completely mechanical without any electronics or drivers. The constant magnetic field generated by the four magnets can last for decades.
TAG Heuer’s pendulum concept, the world’s first clockless movement oscillator, with an oscillation frequency of 43,200 times per hour (6 Hz)-this is the representative of Tag Heuer’s world-leading ultra-high frequency and extreme accuracy. It requires no additional accessories and is purely magnet physics. So it was named after the pendulum clock invented by Huygens in 1675.

里程碑 Technical milestones for the new rise of mechanical movements
The TAG Heuer pendulum concept not only overturns the traditions of watchmaking for three centuries, but also represents a tremendous technological leap forward. The traditional spiral clockwork system has always been the biggest problem due to the effect of gravity due to mass. The TAG Heuer pendulum concept has completely solved this problem for centuries. It can be calibrated with a very high frequency spectrum without using power, so there is no longer the phenomenon of amplitude and frequency attenuation of the movement. Greatly improved accuracy (time division) and performance (frequency accuracy and stability).
The TAG Heuer pendulum concept is the world’s only magnetic oscillator, completely rid of the reaction torque provided by the clockwork: but did not give up the basic principle of the Swiss anchor escapement, because there is no mass effect, it can generate higher frequencies. Also because it can oscillate at very fine angles (the basic principle of the accuracy of the oscillator) without changing its reaction torque, the theoretical accuracy is significantly improved, and more importantly, it will not cause geometric deformation.
Five years of research and development
The TAG Heuer pendulum concept plan combines TAG Heuer’s own R & D engineers and watchmakers, and micro system research experts from the Integrated Actuators Laboratory-LAI. LAI is a microelectronics institute established by the Swiss Federal Institute of Technology in Lausanne, Switzerland. A branch of the Microtechnics Institute of the Swiss Federal Institute of Technology in Lausanne-EPFL.
R & D from scratch begins with advanced digital simulation plus solid analysis (mechanics, magnetism, and thermal induction behavior). After three years of thorough three-dimensional simulation research, the TAG Heuer research and development team finally accurately developed the virtual magnetic spring of the TAG Heuer pendulum concept.
The old problem that still faces: magnets are still affected by temperature. TAG Heuer’s challenge now is to find magnets with characteristics of iron-nickel alloys: in a sense, how to apply Guillaume’s achievements to Huygens’ invention. Once reached, the TAG Heuer pendulum concept will no longer be just a concept, but will become a completely new revolution in mechanical trimmer technology. Creating V4 may still have a long way to go, but TAG Heuer here promises to meet the challenge and create a great epic of the pendulum revolution.
TAG Heuer does not intend to replace the pendulum concept with high-quality Swiss traditional clockwork as the mainstream mechanical movement. On the contrary, it is another option to provide ‘high-end watches’, which will lead another extreme era for the future. This is also the fine-tuning of the Monaco V4 movement Aspirations.
Carrera: Inspired by a luxury racing engine
The Carrella series inherits the passion of racing-like avant-garde design and technology, and is the unparalleled incarnation of TAG Heuer. Since its appearance in 2007, it has a beautiful appearance inspired by modern GT racing cars. With its lightweight, easy-to-read and noble aesthetics, it has immediately received a wide range of responses and is favored by watch and racing fans.
Heuer Carrera pendulum concept design, completely loyal to Carrera’s unique and noble rules: sharp beveled edges, double-sided black titanium steel case. Through the special dial window at 9 o’clock, you can experience the pulse of the avant-garde movement of the TAG Heuer pendulum concept.

The Carella series upholds TAG Heuer’s consistent technical strength and avant-garde beauty
This supreme watch with a noble atmosphere blooming from the inside to the outside is not only a collection of Carrera, but also a model of breakthrough advanced watchmaking technology.
The TAG Heuer Carrera pendulum concept opens a hopeful new generation for the watchmaking industry, with a powerful and precise movement and a more delicate time division. It will have a significant impact on the design and function of the next generation of watches-even though it still takes years of intensive research to come out, TAG Heuer has once again taken the lead.
