Greubel Forsey Tourbillon 24 Secondes Vision






Rapidly rotating 24-second tourbillon, inclined at a 25 degree angle, which for the first time in a Greubel Forsey timepiece is visible from the back of the watch, tucked under a sapphire crystal dome that bulges from the exhibition caseback. This design made it possible for the inclined tourbillon cage to overlap the surface of the movement’s bridges and enabled the watchmakers to make the 18k white gold case extra thin — 13.65 mm high (16.025 mm in total, including the dome) — while still retaining a generous diameter of 43 mm. Also on the back of the watch is the “sector”-style power reserve indicator, which tracks the watch’s 72 hours of energy by means of a pointer and a numbered scale.

The movement, which is comprised of 288 pieces (including 86 in the tourbillon cage alone), features two series coupled barrels that rotate once every 3.2 hours. The free sprung, variable-inertia balance has a frequency of 21,000 vph. Among the technical highlights visible is the distinctly designed lower tourbillon bridge, which calls to mind a Romanesque vault and whose arched and barreled surface is polished by hand.

On the dial side, other than the aperture placed at 9 o’clock, all is understated elegance: lance-shaped blued steel hands that are finished by hand, enameled blue hour numerals and indices that are first engraved then oven-fired to achieve their azure hue, an applied Greubel Forsey logo in gold below the 12 o’clock numeral, a discreet small seconds subdial at 4 o’clock. The dial itself is solid gold, with a silvered finish.
