Double Tourbillon 30° Asymétrique

Double Tourbillon 30° • hours and minutes • small seconds • power-reserve

Greubel Forsey launched the Double Tourbillon 30° Contemporain Vision in 2004. Nearly a decade later, this interpretation features an asymmetric positioning of the Double Tourbillon 30°; which has only previously been presented symmetrically in the collection. To achieve this, the movement architecture has been completely reconstructed, with the outer cage of the patented Double Tourbillon 30° inversed. However, the one‐minute rotation of the inner Tourbillon cage and the four‐minute rotation of the outer tourbillon cage remain the same

The movement is housed in a 43.5 mm diameter case with a curved lateral window in the case band at 8 o’clock. This three‐dimensional opening offers the observer a very special view of the Double Tourbillon system, showcasing the complexity and aesthetic qualities of this unique complication.

The polished conical arm and the flat black polish of the steel tourbillon bridge is one example of Greubel Forsey’s signature superlative hand finishing. The power reserve indicator at 2 o’clock features an innovative rotating disk displaying optimal remaining running time by means of a fixed red triangle instead of a conventional hand.
