In early 2012, TAG Heuer’s award-winning team of engineers and replica watch masters made a radical decision: to start from a blank page, forgetting the hairspring and the balance wheel to repeat, using mechanistic theory, Christian Huygens’ extraordinary accomplishment of 1657— the total reinvention of mechanical watch regulation. The Tag Heuer Carrera Mikrogirder replica watch represents a complete departure from the conventional, 3-centuries-old Christiaan Huygens system, which today still reigns over the mechanical watch industry. Instead of a spiral shape in a classical hairspring, it uses a coupling blade/girder and excitatory blade/girder system working with a linear oscillator.
The Mikrogirder system 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 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.
The Carrera Mikrogirder is an evolution where the original was a revolution, but the changes are more significant than simply being a new coat of paint.
The new Mikrogirder 10000 doesn’t measure time any more precisely than its predecessor, but it does offer several meaningful improvements over the original.
The finish of the case has also changed, with the new model looking more “industrial”- the polished finish has gone, replaced by a “raw” finish.
Topping off the design changes is a new treated leather strap, similar to the one used on the TAG Heuer Monaco V4 Titanium, which replaces the rubber strap of the original.
Following the success of the first model, TAG Heuer followed up in 2012 with an anthracite Mikrograph. The only differences are the colours used on the inner-dial and the leather strap.
To our eyes, the Anthracite strap is a bit of a let down. Most of TAG Heuer’s Anthracite dials have a star-burst metallic finish, but on a leather strap its hard for the colour to appear as anything other than pale Grey.
