GREUBEL FORSEY launches its 8th fundamental invention: the tourbillon universal joint
Greubel Forsey has been developing new tourbillons for many years. Over the past three years, this specific tourbillon has moved coming from concept to reality and is also now revealed as the studio’s eighth fundamental invention. To obtain new levels of chronometric accurate, the Tourbillon Universal Tyre is based on three pillars: a new rapidly rotating tourbillon, the rotating 30° bevel as well as two continuously tilting jewelry.
For twenty years Greubel Forsey has taken care of its position that contemporary the making of watch is far from exhausting each of the technical possibilities of fine horological industry. The studio has confirmed this in seven milestone moments, developing foundational developments that rethink the fundamentals regarding motion regulation and other significant complex functions. This difficult undertaking focused on chronometric efficiency continues today with the start of its eighth innovation: the tourbillon universal joints.
An unmatched tourbillon The tourbillon universal wheel is designed to get to new heights of keeping time precision. It combines about three principles. The first one: tourbillon. Copyrighted by Abraham-Louis Breguet with 1801, the device was designed to make up for differences in velocity and straight position. For Greubel Forsey, this is not the end, but the start.
While most tourbillons rotate at 60 seconds, typically the eighth basic invention revolves almost four times more quickly. It only takes 16 seconds. Here is the fastest Greubel Forsey tourbillon to date. It moves a lot more positions in less time and therefore gives higher average performance.
In addition , this tourbillon uses a large balance tyre designed, developed and created by Greubel Forsey for the first time. That benefits from its mass harmony, large dimensions (12. 6th mm) and optimized shocks. Its high inertia furthermore makes it less sensitive for you to impacts and speed alterations.
The second basic principle: 30° angle. The tourbillon was born more than two generations ago and was made for pocket watches to be put on vertically. For watches, their particular design needs to be completely rethought and optimized for their invest everyday life in the 21st one hundred year.
Third guideline: This 30° high-speed tourbillon is guided by a pair of moving rings and attached by two 90° responsable. For 48 seconds, they will tilted back and forth. This construction may be reminiscent of a common joint, but it is very distinctive from a traditional universal joint, whoever two rings are free to go and their role is to keep your object they contain stage. In a tourbillon gimbal, often the inclination of the ring will be controlled (+30° to -30° range), whereas the tendency of the tourbillon is shifted (also 30°) and never improvements, providing a better angular acceleration ratio. Timing performance.

Observatory reserve of power The tourbillon general wheel has four barrels. This is a remarkable piece of buildings by Greubel Forsey (it only appears once within 20 years). They are piled coaxially with a sliding mainspring to prevent excessive tension in the course of winding. They offer a chronometric power reserve of 80 several hours. Otherwise, the timepiece continue to runs very well, but may possibly fall outside the strict Greubel Forsey precision tolerances.
a new aesthetic Since the tourbillon cannot be saved in place by a fixed higher bridge, this function is conducted by two arched widespread rings. Greubel Forsey’s 9th basic invention creates a fresh tourbillon with a flying physical appearance that does not use traditional buildings and is both original and also patented. Its structure can happen complex, but its minimal quantity of components provides an open, sprawling aesthetic that allows the eye to help freely appreciate its kinematics.
100% palm finished Some elements of the tourbillon universal mutual can take up to three days and nights just to be finished manually ,. A variety of unique finishes are already developed specifically for this see. Among them, the movement splint is made of frosted nickel magic with polished bevels along with straight-grained flanks, while the ti alloy main plate gifts a large area of polished flanks as the background of the worldwide joint. Even more special: the top bridge of the tourbillon competition is made of brushed titanium, using straight grained sides in addition to polished bevels, above as well as below. Finally, the rebattu are barrel polished. It was a little while until over 30 hours to finish this single component.
The universal band has a matte finish having polished bevels and dominated sides, while the lower platter is hand-brushed, a task that will require Atelier Manufacture's special competence to complete. Finally, there are a couple dials (hours, minutes and also seconds), one with finished sides and a circular structure with very large mirror sides, the other with polished exterior sides.
Greubel Forsey also developed any high-domed sapphire crystal in this piece. It accommodates the complete height of the tourbillon along with cardan wheel system, offering a highly architectural view in the technology. The view over the 10. 6 mm diameter sense of balance wheel is completely unobstructed. It is possible to admire the majestic swing action of the two universal engagement rings it is mounted on.
The Tourbillon Gimbal observe is housed in a forty-five. 5mm titanium case. This specific metal was chosen for the modernity and lightness, consistent with the light aesthetic of the Cardan Tourbillon.
Greubel Forsey Since its starting in 2004, Greubel Forsey possesses continued to pursue superiority and is active at the front of high-end watchmaking, developing and producing timepieces famous for their exceptional quality. Sartoria Manufacture, located in La Chaux-de-Fonds (Switzerland), brings together exceptional skills, extraordinary innovation and unusual excellence in craftsmanship. Greubel Forsey has “the skill of invention” as its standards: since its founding, the brand features conceived, patented and produced seven fundamental inventions who have fundamentally changed the world of excellent watchmaking. All Greubel Forsey timepieces adhere to 5 rules: invention and innovation; hand-made and hand-finished; performance in addition to reliability; architecture and layout; rarity and exclusivity. Together with complete mastery of style and design and manufacturing processes and also a relentless pursuit of excellence, the brand name has become one of the best names inside technical and contemporary okay watchmaking in just a few years. Today in its 20th anniversary, Greubel Forsey has become fully indie and has embarked on a fundamental modification from a creative workshop in to a full-fledged watch brand.
