Just Arrived: New Blue Dial Double Balancier à Différentiel Constant from Greubel Forsey

The new Double Balancier à Différentiel Constant.

Greubel Forsey presented the first Double Balancier à Différentiel Constant – the result of painstaking years of research – at SIHH earlier this year. The brand has unveiled a follow-up to the acclaimed model, a unique white gold version with a striking blue dial that is only available at Cellini Jewelers.

Redefining the Limits of Chronometry

This new mechanism pushes the limits of timekeeping. Two inclined balance wheels optimize performance in stable positions, while the Differentiel Spherique Constant provides more steady amplitude.

The differentiel spherique constant at the heart of the movement.

Augmented Architecture

Aesthetically, this timepiece is both understated and yet complex. The eye-catching wide aperture with powerful three-dimensional aspects, extensively reveals the heart of the mechanism. We dive into an architectural world built on many levels, a miniature futuristic city constructed between the balance wheels whose inclination is almost dizzying.

Robert Greubel and Stephen Forsey began to research multiple regulators in 1999 as part of their EWT (Experimental Watch Technology) platform. The first prototype to feature a fixed oscillator, the Double Balancier Incliné, was presented at Baselworld in 2009, as the sixth Greubel Forsey invention. The two inclined balance wheels – initially positioned one above the other – now occupy distinct and separate three-dimensional spaces. This new configuration is responsible for improved chronometric performance, while the Differentiel Spherique Constant cuts the margin of error in half.

Excellent Craftsmanship

Once again, this timepiece stands out by virtue of the extreme attention paid to its finishing. These include the three-dimensional, geometric lugs and the raised, polished engraving on a hand-punched background.
