Greubel Forsey – Tourbillon Universal Wheel
Greubel Forsey has been developing new tourbillons for many years. Over the past three years, this tourbillon has evolved from concept to reality and is now the studio’s eighth fundamental invention. replica Greubel Forsey GMT Watches
The new tourbillon universal wheel aims to reach new heights of timekeeping precision and combines three main principles.
The first one: Tourbillon. Patented by Abraham-Louis Breguet in 1801, this mechanism was designed to compensate for differences in rate in vertical position. Unlike most tourbillons, which rotate once in 60 seconds, the eighth basic invention rotates nearly four times faster. It only takes 16 seconds. This is the fastest Greubel Forsey tourbillon to date. It can move more positions in less time, providing significantly higher average performance.
This tourbillon also uses a large balance wheel designed, developed and manufactured by Greubel Forsey for the first time. It benefits from its mass balance, large dimensions (12.6 mm) and optimized vibrations. Its high inertia also makes it less sensitive to impacts and speed changes. replica mens watches
The second principle: 30° angle. The tourbillon was born more than two centuries ago and was designed for pocket watches to be worn vertically. For watches, their design needs to be completely rethought to adapt to their place in everyday life in the 21st century.
Third principle: This 30° high-speed tourbillon is guided by two moving rings and connected by two 90° axes. For 48 seconds, they tilted back and forth. This structure may be reminiscent of a universal joint, but it is very different from a traditional universal joint, whose two rings are free to move and their role is to keep the object they contain level. In a tourbillon gimbal, the inclination of the ring is controlled (+30° to -30° range), whereas the inclination of the tourbillon is inclined (also 30°) and never changes, providing a better Angular velocity ratio.

Since the tourbillon cannot be held in place by a fixed upper bridge, this function is performed by two arched universal rings. Greubel Forsey's eighth basic invention does not use traditional structures to create a new tourbillon with a flying appearance, which is both original and patented. A deceptively complex structure, but with a minimal number of components, it offers an open, airy aesthetic that allows the eye to freely appreciate its kinematics.
The tourbillon universal wheel has four coaxially stacked barrels and is equipped with a sliding mainspring to prevent excessive tension during the winding process. They offer a chronometric power reserve of 80 hours. Otherwise, the timepiece still runs well but exceeds the strict Greubel Forsey precision tolerances. luxury replica Watches
As you can imagine, the finishes are of the highest standard, some of which were developed specifically for this timepiece.
The movement plate is in matte nickel silver with polished bevels and ruled sides, while the titanium main plate presents large polished sides that serve as a backdrop for the gimbal.
The upper bridge of the tourbillon cage is made of brushed titanium, with straight grained sides and polished bevels, above and below. The arches are barrel polished. It took over 30 hours to complete this single component.

Finally, there are two dials (hours/minutes and seconds), one with polished sides and a circular texture with very large mirror angles, and the other with polished outer sides.
Greubel Forsey also created a high-domed sapphire crystal for this piece. It accommodates the entire height of the tourbillon and cardan wheel system, providing a highly architectural view of the technology.
The Tourbillon Gimbal is housed in a 45.5mm x 13.81mm (or 18.15mm including sapphire crystal) titanium case. This metal was chosen for its modernity and lightness, in keeping with the light aesthetic of the Cardan Tourbillon. Guaranteed waterproof pressure up to 3 bar. Jacob & Co Astronomia replica
