In fact the MikroS, for short, uses not one but two tourbillons (thus why TAG Heuer insist on spelling the name as such to emphasis that the watch has two tourbillons). This is quite an odd movement coming from the Swiss manufacturer, but odd isn't necessarily a bad thing. By using two tourbillons - one to regulate the time, and one to regulate the Chronograph - the watch is allowed a precision of 1/100th of a second, making this timepiece the fastest tourbillon in the world. The Chronograph escapement vibrates at 360,000 vibrations per hour (50hz) and is regulated by a tourbillon that rotates once every 5 seconds. Power reserve is 45 hours for the watch and 60 minutes for the Chronograph.
While the movement may be considered extreme, the design is humble. A 45mm Carrera case finished in Rose Gold contrasts a light black face with 3 sub-dials (chronograph minutes, chronograph seconds, and power reserve) as well as some open-work revealing the the watches two tourbillons. The dial consists of two halves- the right side, which houses the sub-dials, finished in an anthracite Côtes de Genève pattern, and the left side which shows off the the two stunning tourbillons. Overall the design isn't all too intricate, yet it it seems to perfectly suit the piece. What you get is a watch that demands attention yet doesn't do so in that gaudy manner which many other Swiss pieces tend to do.
The MikrotourbillonS is a stand-out piece from TAG Heuer. Simple artistry and mechanical excellence is what haute horology is all about; the MikroS embodies this notion.
The piece will be available later this year in a non-limited edition form, but that still doesn't make them cheap. You can pick one up for around $225,000.
