Greubel Forsey debuts a new twist to its convex case series with the new Tourbillon 24 Secondes Architecture.
Unlike existing watches in the ‘Convexe’ series, this new model features a case that, in addition to its convex curve, also widens as it reaches the wrist. Thus, with a diameter around the caseback (47.05mm) that is wider than the bezel (45mm), it fully exhibits the impressive movement inside while also appearing smaller than it actually is.
Known as a ‘conical frustrum’ in geometry, the unusual case shape, especially with its side-case clear sapphire windows, creates a broad showcase for Greubel Forsey’s exceptional Tourbillon 24 Secondes movement.
On the wrist the titanium watch is comfortable and endlessly fascinating, especially given the ability to admire the movement’s highly polished moving parts directly through the case sides.
From the top the wearer sees the relief-engraved Greubel Forsey text “Architecture, Harmonie, Innovation, Technique, Bienfacture, Passion, Science, Exclusivité, Créativité” just inside the convex bezel. The new, contemporary font seems to announce a new era in case making for the newly independent watchmaker, which spent years perfecting this new design.
Superb chronometry
But within that bezel, when peering in from all sides, the viewer sees all the Tourbillon 24 Secondes Architecture components seemingly suspended within what may be the watchmaker’s deepest case, which measures 16.8mm from top to bottom. (The recent convex-cased Balancier S measures 13.75mm deep, in comparison.)
With the new case, light enters the case from all sides and creates shadows and reflections that only enhance the appearance of depth within.
The watch’s showpiece Tourbillon 24 Secondes takes center stage at the 6 o’clock location. With its inclined escapement and fast rotational speed, it demonstrates superb chronometric performance.
Visible from multiple sides of the case, the inclined escapement and the other primary components (the power reserve indicator and the decorated coaxial-series barrel) are each attached to highly polished titanium bridges.
Greubel Forsey has equipped one of those barrels with a slipping spring to avoid excess tension. The barrel provides ninety hours of power reserve, which is indicated by a moving red triangle over a conical disk at 3 o’clock.
Greubel Forsey will make only eleven Tourbillon 24 Secondes Architecture watches in 2022, followed by eighteen pieces a year between 2023 and 2025 for a total of sixty-five timepieces overall.
