Double Tourbillon 30° Secret

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

Dedicated to connoisseurs of Haute Horlogerie with a preference for discretion and for whom observing the mechanism is an intensely personal pleasure, the Double Tourbillon 30° now appears in a less extrovert and one might almost say ‘secretive’ style, even though such a splendid dial naturally hints at the treasure it is guarding. This exquisitely crafted matt-finished gold dial suggests the presence of an exceptional mechanism, thanks to its unusual and particularly wide subdial at 6 o’clock with a slender blued steel hand testifying to the four-minute rotation of the outer cage of the Double Tourbillon 30°

Fortunately however, the secret of this Double Tourbillon 30° is not impenetrable and, although hidden from view on the wrist, the choreographic performance of the cages may nonetheless be admired through the case-back protected by a domed sapphire crystal. The 128 parts making up the first fundamental Greubel Forsey invention weigh a total of 1.17 grams, enabling the variable-inertia balance to oscillate to and fro three times a second, whereas its rotation axis shifts constantly due to the relative speeds of the cages and the 30° angle that links them together.
