After years of research and development, Robert Greubel and Stephen Forsey are particularly proud to introduce a timepiece containing their fifth basic invention: Différentiel d’Égalité. It ensures the driving force of the adjustment and improves the accuracy of the timing performance. This is also the first time that Koppelforth has integrated non-jump seconds in one of its timepieces.

Jump-free seconds and performance
This is the first creation of Robert Goldberg and Stephen Fauci, this timepiece has a non-jumping seconds function. This makes it easier to read and accurately set the time. The timepiece is equipped with a balance wheel stop device and a second hand reset device, which can be started by pulling the crown. The heart and hammer of the device are visible on the side of the movement. The 30° angle of the balance wheel and escapement minimizes the influence of gravity and ensures efficient movement performance in a stable position. This Koperfuss technology guarantees excellent average/average balance wheel performance, which is a sign of improved timing accuracy. All these components work together to help improve performance.

Mechanical spirit
The aesthetics of this timepiece is derived from the purest everything in the mechanical spirit of Gao Peifusi. The large opening on the dial allows you to see all the beauty and complexity of the movement. The side of the dial is decorated with a high arched sapphire crystal glass, giving this new work a delicate outline. The side of the movement displays the “Stop/Reset” mechanism and inscriptions with inscriptions that summarize the key values ​​that Robert Gopper and Stephen Fauci instilled in their creations. wholesale watches
