Greubel Forsey Dual Tourbillon Top Watchmaking

Greubel Forsey stood out in this top field of watchmaking when the new generation of tourbillons flocked.

The fine and novel twin-body flywheel 30o is a tourbillon sleeve tourbillon with two rotating brackets connected at a 30 degree angle. According to its creator, the main advantage of the third millennium tourbillon is that it can compensate for the difference in operation (gravity caused) not only in the vertical position but also in any position. The result of the six position measurements is that the watch is more accurate than the classical tourbillon (plus or minus seven seconds): the Greubel Forsey dual tourbillon 30o only has a plus or minus two second error.
