It was 2004 when Tag Heuer created a buzz presenting the Monaco V4 Concept Watch, the world’s first watch with belt drives, linear mass and ball bearings whose V4 name derived from the V-shaped main plate on which the movement's four barrels are mounted.
Five years later, in 2009, the concept watch became a production model. This year, during the BaselWorld 2014 event, Tag Heuer presented the Monaco V4 Tourbillon, a watch which combines one of the most remarkable innovation in watchmaking of the last decade with one of the symbols of classical Haute Horlogerie, the tourbillon.
Traditionally, the tourbillon is a mechanical system which overcomes the effects of gravity by placing the balance wheel and escapement inside a rotating cage. In this case, the tourbillon is driven by a micro-belt which guarantees the absolute fluidity of its 1-per-minute rotation.
The case back displays the revolutionary automatic linear rewinding system, where the mass - a tungsten bar - is guided by a linear railroad instead of a traditional rotating system. Two pairs of barrels are linked by a belt, set in parallel and inclined at 13 degrees. They deliver a power reserve of 40 hours.
The 41 mm x 41 mm Monaco case is made of polished titanium with black titanium carbide coating. It offers water resistance to 50 metres.
The Tag Heuer Monaco V4 Tourbillon (ref. WAW2081.FC6348) has a price of 150,000 Swiss Francs.
