Introducing the TAG Heuer Mikrotourbillon S, a wristwatch equipped with two tourbillon escapements, one for the chronograph and the other for timekeeping. The functions runs autonomously of one another. One tourbillon runs at 4 Hz and controls the timekeeping. The other tourbillon runs at 50 Hz and controls the chronograph, which can measure events to 1/100th of a second. The latter completes an entire revolution in a mere five seconds, making it twelve times faster than a standard tourbillon, which takes one-minute to complete an entire revolution.
"According to Semon, every component for the Mikrotourbillon S mechanism, with the exception of its two hairsprings, is made in-house at TAG Heuer's La Chaux-de-Fonds factory."
Unlike many cutting edge timepieces, the Mikrotourbillon S is not a concept, it will be for sale very soon. The price is $225,000.
