Greubel Forsey Double Balancier Convexe
The timepiece, constructed in titanium, emphasizes architectural design and incorporates a Double Balancier movement with a constant spherical differential. Share
Greubel Forsey is making waves in the watchmaking world with the release of its Double Balancier Convexe in a new 42.5 mm diameter. Crafted in titanium, this limited edition of only 88 pieces represents a leap in architectural ingenuity surrounding its Double Balancier movement and constant spherical differential.
What sets Greubel Forsey apart is their principle of the unique creative process, “one calibre – one case.” At their Atelier Manufacture, the development of each watch is an inseparable journey from concept to assembly, and nowhere is this more evident than in the Convexe collection. With a double-curved case designed to perfectly embrace the wrist, the construction of the movement is brought to the forefront in three dimensions.
Challenging even the standards set by Greubel Forsey themselves, the newly announced 42.5 mm Double Balancier Convexe aims to encapsulate the timepiece in a more compact form while maintaining its elegant proportions and architectural integrity. To accomplish this, the construction of the movement had to be reinvented and the finish enhanced. This refinement was only made possible by the skilled artisans at Greubel Forsey’s workshops, with each piece meticulously assembled and finished by hand.
The original Double Balancier Convexe was launched in 2022, not initially designed for the 42.5 mm diameter. The substantial reduction in size is a notable achievement, given that Greubel Forsey’s watches are fine-tuned to the micron. Discerning collectors will recognize the significance of this evolution.
Inside the smaller 42.5 mm-diameter case lies the remarkable Double Balancier movement, the sixth Fundamental Invention from Greubel Forsey. This invention, patented in 2007, has gone through various evolutions, eventually resulting in two balance wheels inclined at 30°. The new diameter allowed for a novel approach to the Convexe case, as the Greubel Forsey teams adapted the unique convex profile, ensuring optimal comfort and maintaining the brand’s commitment to ergonomic excellence.
The result is a harmonious timepiece, offering a discreet silhouette that doesn’t compromise its design integrity. Whether slipped under a fitted sleeve or worn openly, collectors can choose to display or conceal the intricate movement mechanics without any ostentation.
The attention to detail extends to the finishing. With a natural titanium case that offers a silky grey glow, polished bezel, and satin finishes, the aesthetic plays on contrasts and elegance. The lettering on the barrel cover and the redesigned case adds a dynamic flair, promising 72 hours of chronometric power reserve. Moreover, the use of titanium for the mainplate and the hand-polished bevelling of each balance wheel’s bridge showcases an ambitious and meticulous craftsmanship.
At the heart of the timepiece, the Constant Spherical Differential links the inclined balance wheels and is visible between 6 and 7 o’clock. Its 4-minute sequences ensure the best running average, meeting Greubel Forsey’s demanding standards for performance, precision, and reliability.
The 42.5 mm Double Balancier Convexe is offered with a grey rubber strap or an integrated Greubel Forsey titanium bracelet, and this new release will no doubt resonate with collectors and enthusiasts looking for a blend of architectural sophistication and cutting-edge design.
