THE NEW GREUBEL FORSEY FLAGSHIP
With the GMT Sport and the original Balancier S, Greubel Forsey revealed a new facet of its identity. This highly contemporary and exciting approach to fine watchmaking has just been raised to the power of 2, amplifying the very essence of Greubel Forsey.

The Greubel Forsey Balancier S² isolates the most powerful elements of the original Balancier S and accentuates and modernises them. Instead of soft curves and a discreet overall aesthetic, the Balancier S² is all about contrast and power. It shares the movement of its predecessor but introduces a new case, new finishing and new design codes.

Greubel Forsey chose to accentuate the contrast – and therefore the legibility – of its dial, with an intense black or grey backdrop that cuts through the balance bridge between 5 and 9 o'clock.

The edges are sharp and the matt-effect hand- grained finish allows the bridge and indices to stand out much more clearly. The latter have been reduced to their simplest expression, with 12 towering indices for 12 hours.

For the first time, the central double-arched titanium bridge which holds the gear train is openworked: once again, we can see the desire to lighten, purify and return to the essential. The new titanium bracelet reinforces this dynamic. It offers perfect continuity with the titanium case, exuding a robust and contemporary appeal.

The Greubel Forsey Balancier S² affirms its place in the Haute Horlogerie of today and tomorrow as a timepiece that sacrifices nothing to the excellence of high-end watchmaking. Yet it’s a timepiece designed for everyday use, not one to simply be stored away in a safe.

The Balancier S² also features a slightly larger diameter that helps assert its new personality. Increased to 46.5mm, it is now topped by a striking brushed titanium bezel with polished flanks, instead of the key Greubel Forsey values.

Similarly, the barrel cover no longer features the large “Greubel Forsey” signature, but instead a very modern circular pattern designed exclusively for this model. The Greubel Forsey signature appears under the internal bezel between 12 and 2 o’clock. Suspended high above, the hour and minute hands appear in luminescent white.

A focus on chronometry
The large inclined balance wheel at 7 o’clock stands out. Aiming above all to improve chronometry, it maximises the space offered by the arched case and sapphire crystal, inextricably linking form and function.

In their relentless quest for precision and performance, Robert Greubel and Stephen Forsey have already challenged chronometry, notably by reinventing the tourbillon mechanism with the Tourbillon 24 Secondes, Quadruple Tourbillon and the Double Tourbillon 30°. They chose a new approach here, based on their large balance wheel unveiled in 2016.

Entirely developed and made within the Greubel Forsey Atelier, this balance wheel is distinguished by its oversized 12.6mm diameter, ensuring excellent timekeeping performance.

To allow fine timekeeping adjustment of the moment of inertia, the
balance wheel rim is fitted with six gold regulating screws, inset so as
to limit air friction. In this new hand wound calibre, with several
patents pending, the imposing Greubel Forsey balance wheel can be seen in an inclined construction for the very first time.

This 30° angle with respect to the horizontal plane of the movement proves to be an outstanding solution for limiting timing errors due to the effects of gravity on the regulating organ (balance wheel, spring and escapement) in stable positions.

Combined with the large diameter of the balance wheel and the frequency of 21,600 vibrations/hour, it provides this timepiece with excellent chronometric performance – it’s also prominently visible in action due to the unique movement architecture.
With two coaxial barrels mounted in series, the 307-component movement has a 72-hour chronometric power reserve, indicated on a sector at 2 o’clock using an openworked red-tipped hand.

The central hours and minutes display, with profiled and openworked
polished steel hands, is completed by a small seconds hand on the
inclined plane of the escapement at 8 o’clock, accentuating the depth and relief of this new calibre.

Following the Greubel Forsey creative spirit, technical and
architectural innovation is accomplished with unconditional care and
craftsmanship for all the components of the movement – whether these are
visible through the sapphire crystal, the transparent caseback or
hidden in the mechanical mysteries within.

This traditional and irreplaceable artisanal know-how is mastered in the Greubel Forsey Atelier – frosting, polished bevels and countersinks, circular and straight graining highlight even the smallest surfaces. The use of titanium for the mainplate and bridges proved much more difficult for manual hand-finishing than steel or even nickel silver and further increases the technical and aesthetic challenge that this timepiece represents.

S² for sport
The exceptional chronometry of this Greubel Forsey creation is combined with an unequivocally sporty case. Made of titanium and water resistant to 100 metres, its powerful case shape is distinguished by its lightness and comfort on the wrist. Its robustness protects the movement, in particular its large balance wheel, tested in the Greubel Forsey EWT Laboratory assuring its reliability and chronometric performance at all times.
