Greubel Forsey Double Tourbillon 30° Asymétrique is a wristwatch by Greubel Forsey.
One of the special features of this reinterpretation lies in the unusual positioning of the rotating Double Tourbillon cage system, between seven and eight o'clock. This Double Tourbillon 30° has been redesigned and now features a new tourbillon bridge, to be displayed “in reverse”.
The hand-wound calibre comprises 319 components, including 130 for the cages. It is powered by two mainspring barrels with a 72-hour power reserve oscillating at 3 Hz/21,600 vibrations per hour. The inner cage at 30° and the outer cage rotate in 1 and 4 minutes respectively. The asymmetric case measures 43.5 mm in diameter and 16.13 mm in height. It features an asymmetric sapphire crystal for the display and the back, and a side window.
