TAG Heuer is introducing [in Geneva] a new milestone in the history of mechanical regulation and high-speed frequency movements. You will certainly remember, that almost one year ago, the Mikrotimer, ?the world's first-ever mechanical chronograph to measure and display the 1/1,000th of a second, making it 125 times more accurate ?than most existing mechanical chronographs on Earth.This year, TAG Heuer went beyond and presents the Mikrogirder.
