Greubel Forsey – Double balancer

Greubel Forsey exclusively launched the first double balancer à Différentiel Constant, which is the result of years of painstaking research.

This new mechanism breaks the limits of timekeeping. Two inclined balance wheels optimize the performance of stable position, while the differential spherical constant provides a more stable amplitude.

Aesthetically, this timepiece is both low-key and complex. The eye-catching large aperture has a powerful 3D effect, fully demonstrating the core of the mechanical device. We dive into a world of architecture built on multiple levels, a miniature futuristic city built between balance wheels, the slope of which is almost dizzying.

Robert Greubel and Stephen Forsey began working on multiple regulators in 1999. The first prototype with a fixed oscillator, Double Balancier Incliné, was exhibited at Baselworld in 2009 as Greubel Forsey’s sixth invention. The two tilted balance wheels-originally one placed on top of the other-now occupy a unique and independent three-dimensional space. This new configuration helps improve timing performance, and the differential spherical constant reduces the margin of error by half.

Once again, this nice watches stands out because of its high attention to surface treatment. These include three-dimensional geometric lugs and raised polished engravings on a hand-stamped background.
