In the hallowed halls of Greubel Forsey , where time is not merely measured but choreographed with utmost precision, emerges the Tourbillon Cardan – a symphony of innovation and craftsmanship. Celebrating two decades of pushing the boundaries of horological excellence, Greubel Forsey introduces its 8th Fundamental Invention, a tour de force that redefines the very essence of contemporary watchmaking.
At the core of the Tourbillon Cardan are three fundamental principles, each contributing to its unparalleled chronometric precision. The first principle introduces a rapid rotating tourbillon, a mechanical dance that defies convention. Unlike traditional tourbillons with a 60-second revolution, Greubel Forsey’s creation completes its mesmerizing spin in just 16 seconds. This remarkable speed allows for more positions, translating to higher average performance.
Adding to this, the tourbillon boasts a large balance wheel, a masterpiece meticulously designed and crafted in-house. With a diameter of 12.6 mm, this balance wheel exhibits optimal balance of masses, size, and oscillations, rendering it less susceptible to shocks and speed variations.
The second principle introduces a revolutionary 30° inclined plane, challenging the historical design of the tourbillon. Crafted for the dynamics of a wristwatch in the 21st century, this angle optimizes the timepiece’s performance in everyday scenarios.
The third principle involves the guidance of the high-speed tourbillon by two mobile rings, a construction akin to gimbals but with a unique twist. Controlled within a range of +30° to -30°, these rings ensure a consistent degree of inclination for the tourbillon, providing an exceptional ratio of angular velocity to chronometric performance.
Beyond its technical prowess, the Tourbillon Cardan is a work of art, a harmonious blend of complexity and simplicity. The four coaxially stacked barrels offer an 80-hour chronometric power reserve, a remarkable feat in itself. The absence of a fixed upper bridge is compensated by the elegant arches of the cardan rings, creating a visually striking “flying” appearance.
The aesthetic journey continues with hand-finished components that require days of meticulous attention. Frosted nickel silver, polished bevels, straight grained flanks, and a titanium mainplate showcase a level of craftsmanship that is synonymous with Greubel Forsey’s legacy.
Housed in a 45.5 mm titanium case, the Tourbillon Cardan exemplifies modernity and lightness, aligning seamlessly with its airy aesthetic. Completing the masterpiece is a high-domed sapphire crystal, offering an unobstructed view of the majestic swaying of the two cardan rings. This architectural marvel allows enthusiasts to witness the inner workings of the tourbillon and cardan system, providing a visual spectacle that goes beyond mere timekeeping.
Greubel Forsey plans to produce only 55 pieces of this exceptional caliber over the next five years, adding an element of exclusivity to its already distinguished allure.
