DOUBLE TOURBILLON 30° TECHNIQUE

A contemporary watchmaking icon, the Double Tourbillon 30° Technique embodies Greubel Forsey’s technical virtuosity and sculptural vision. 

With its commanding 47.5 mm red gold 5N case, the Double Tourbillon 30° Technique stands as a true statement of Greubel Forsey’s expertise. The openworked dial exposes the tridimensional depth of the hand-wound GF02s calibre, composed of 396 parts and four coaxial barrels in series, ensuring a 120-hour power reserve.

At its core lies the patented Double Tourbillon 30° —an inner cage inclined at 30° rotating once per minute inside an outer cage completing a four-minute revolution— designed to optimise chronometric precision. At 3 o’clock, the power-reserve indicator; at 9 o’clock, the small seconds; and at 6 o’clock, the mesmerising dance of the tourbillon.

Nickel bridges, gold chatons and immaculate hand finishing reflect the brand’s devotion to perfection. Hand-engraved plates on the case sides express the maison’s values (Inventeurs Horlogers, Savoir-Faire, Créativité) while the black alligator strap with red gold folding clasp seals the encounter between artistry and mechanics.
