TAG Heuer Mikrogirder watch
Simpler, faster and more efficient than science dreamed possible, impervious to gravity and dramatically reducing isochronous error, potentially easier to manufacture and able to precisely measure time to a phenomenal 5/10,000th of a second today, and probably even more precisely tomorrow…

Reinventing the mechanical regulator




The TAG Heuer Mikrogirder has won this year’s Aiguille d’Or, the top prize at the Geneva Watchmaking Grand Prix ceremonies, and the most coveted distinction in the global watch industry.
The Foundation annually organises the Geneva Watchmaking Grand Prix (GPHG), which is intended to salute the excellence of worldwide horological production and annually rewards the finest creations and the most important operators in the watchmaking sector.
“We’re absolutely ecstatic,” said Jean-Christophe Babin, TAG Heuer President and CEO.
“We’ve won our share of Grand Prix over the years but this is the first time we have been singled out as the best overall watch in all categories.”
With this 8th Grand Prix de l'Horlogerie de Genève award in just 11 years, TAG Heuer confirms its unrivalled mastery of extremely complex timepieces.
"We’re very proud of this achievement", said Jean-Christophe Babin, TAG Heuer President and CEO. "The Mikrogirder represents a new class of watch technology, nothing less than the complete re-invention of the mechanism that has driven mechanical watches for over 300 years."
A completely new system regulates the watch: instead of the spiral shape in a classical hairspring, it works with a coupling beam/girder and excitatory beam/girder system and a linear oscillator.
Conceived, developed and manufactured in-house in the company’s R&D lab in La Chaux-de-Fonds, Switzerland, it is the fastest mechanical regulator ever crafted and tested.
"We are grateful to the jury for acknowledging this breakthrough", said Jean-Christophe Babin. "The Mikrogirder changes the way mechanical energy is generated, stored and regulated. It opens a promising new era in watchmaking, with potentially powerful and energy-sparing new movements precise to ever-smaller fractions of time. We're already well underway to fully exploring the possibilities."


Now comes the pioneering Mikrogirder, TAG Heuer’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.
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. Overturning three centuries of watchmaking convention in the way mechanical energy is generated, stored and regulated, the mikrogirder opens a promising new era in watchmaking, with potentially powerful and energy-sparing new movements precise to ever-smaller fractions of time.
Accurate to an unprecedented 5/10,000 of a second, the mikrogirder is a completely new regulator system — a coupling blade and excitatory blade 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 major 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).
1’000 hz / 7’200’000 beats per hour
5/10’000th of a second
250 times faster than classical 4hz chronograph
