Conceived, developed and manufactured in-house in the company’s R&D lab in La Chaux-de-Fonds, Switzerland, the MIKROGIRDER is the fastest mechanical regulator ever crafted and tested.  Accurate to an unprecedented 5/10,000 or 1/2,000th of a second, the MIKROGIRDER is a completely new regulator system — a coupling beam/girder and excitatory beam/girder system working with a linear oscillator (versus a spiral shape in a classical hairspring) that vibrates isochronously at a very small angle, as opposed to a traditional watch, which vibrates at an angle of up to 320 degrees.

The advantages are numerous. In a classic spiral hairspring system, the effect of gravity due to mass is a dominant issue. With the MIKROGIRDER, the problem no longer even exists. There is no loss of amplitude and the movement’s frequency can be modulated on a very large spectrum of frequency without overburdening the power supply. The result is a significant increase in precision (division of time) and performance (frequency accuracy and stability). The MIKROGIRDER energy performance will enable TAG Heuer chronographs to attain ultra-high frequencies never before dreamed possible. Ten patents are pending on this breakthrough.

The MIKROGIRDER’s dual frequency system ensures precision and chronometry through 2 independent chains. As there is no possibility of interference between “normal speed” and “high speed”, there is better precision and accuracy. The power reserve is improved, too, and wear and tear dramatically reduced, as “high speed” is “on demand” instead of being always engaged. Finally, the dual frequency system offers the ultimate in readability.The smallest fraction of time — 1/100th, 1/1,000th and ½,000th (5/10,000) of a second — is displayed on a central hand that does a complete revolution around the dial a mind-boggling 20 times per second. Furthermore, and like the Mikrotimer Flying 1000, the dial display allows a quick and easy reading of the incredible measurement thanks to 3 scales, 2 external and one at 6 o’clock allowing to read 5/10,000 or 1/2,000ths of a second.

True to its “Technology and Design” DNA, TAG Heuer has embedded this mechanical engineering masterpiece in a new stunning asymmetric chronograph case design. Though the placement of the crown at 12 o’clock is inspired by the 1/100th of a second Heuer stopwatches of the 1920s, the overall design is decisively avant-garde. The unconventional shape and wide opening makes for easier reading, while the dial design allows one to see the beam/girder regulator system “at work”. A new Concept masterpiece from TAG Heuer, it could very well become a commercial piece like most of its Concept predecessors of the last 10 years, including the Monaco V4, the Calibre 360, the Monaco 24, the Mikrograph 100, and, since the end of 2011, the Mikrotimer Flying 1000.

TAG Heuer Concept History

In 2010, TAG Heuer presented the Grand Carrera Pendulum Concept, the world’s first-ever mechanical regulator to replace a conventional hairspring with magnets. Following TAG Heuer’s Calibre 360 Chronograph (2005), which beats at 50Hz and measures and displays to the 1/100th of a second, the 6Hz Pendulum Concept, which is still under development, confirmed TAG Heuer’s position as the unrivalled pioneer of high frequencies.

In 2011, TAG Heuer launched the MIKROTIMER FLYING 1000, the world’s first 500hz mechanical chronograph. A revolutionary mechanical chronograph regulator without any balance wheel system and equipped with two escapements, the Mikrotimer’s beats 3.6 million times per hour, making it 125 times faster than a standard Swiss chronograph. Its central chronograph hand completes a full rotation 10 times per second. Now being successfully commercialized, the Mikrotimer was voted the 2011 Swiss Sports Watch of the Year at the Geneva Watchmaking Grand Prix. The victory marked the 7th time in 10 years that TAG Heuer was singled out by the Geneva jury for its engineering and design prowess.

Now comes the pioneering MIKROGIRDER, the Swiss legend’s greatest achievement in watchmaking engineering to date, a game-changing technology which promises to completely revolutionize the very heart of the watch — the regulator. More than the Pendulum or the Mikrotimer, the MIKROGIRDER represents a total departure from the conventional, 3-centuries-old Christiaan Huygens system, which today still reigns over the mechanical watch industry.
