Greubel Forsey revealed the exceptional Tourbillon 24 Secondes Architecture with a brand new calibre. The timepiece features an atypical case that houses components suspended in space and features a large opening on the dial side to allow a detailed look at even the smallest detail of the movement.
The case looks perfectly round when seen from the dial side, however, it reveals its convex shape from other angles, along with its large synthetic sapphire crystal ring which envelopes the entire periphery of the caseband. Greubel Forsey has never before rendered a movement visible from above, below, and from every angle around the caseband.
The convex shape profile of the case ensures optimal ergonomics and wrist comfort. In the Tourbillon 24 Secondes Architecture, the diameter around the caseback (47.05mm) is wider than it is around the bezel (45.50mm). It contains enough volume to fully showcase the movement architecture within, while at the same time giving the impression of being significantly smaller than it actually is. The 50m water-resistant titanium case features three-dimensional, variable geometry lugs, hand-polished with handfinished straight graining, flowing seamlessly into a rubber strap.
The 354 parts of the movement are suspended in an unexpected three-dimensional plane. The Greubel Forsey movement features the polished titanium bridges that wind their way through the movement to finally impose themselves flush with the sapphire crystal. At 6 o’clock, the Tourbillon 24 Secondes is moored from a large spherical and openworked bridge, whose base remains concealed by design. The watch uses a fast rotation speed in addition to a 25° inclination. These two elements contribute to excellent chronometric performance, especially in stable positions.
The barrel bridge at 10 o’clock features polished spherical surfaces, along with polished beveling and countersinks. The barrel cover is engraved, lacquered and circular-grained and contains three coaxial series-coupled fast-ro- tating barrels, one of which is equipped with a slipping spring to avoid excess tension. The caliber’s energy source provides 90 hours chronometric power reserve, indicated by a moving red triangle over a conical disk at 3 o’clock. It too is held in place by a beautiful polished titanium bridge.
In the center, there are two large curved, open-worked, and polished steel hands mounted on a signature Greubel Forsey tripod bridge. The time indication is completed at 8 o’clock by a small second on a cylinder with polished flanks.
The Tourbillon 24 Secondes Architecture will be limited to only 11 pieces this year, then to 18 pieces a year between 2023 and 2025 for a total of 65 exclusive timepieces overall.
