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…
