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.

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 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.

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.

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.

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.

88 pieces of this new
Balancier S² will be made for the version
with a charcoal grey backdrop, for a total of
22 pieces per year from
2022 to
2025. For the version with a light grey background,
16 pieces
per year will be released over
4 years, totalling
64 pieces. Both
versions will come in a titanium case
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.
Click , to see the large size. ▶ BIG FOTOIn 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.
Click , to see the large size. ▶ BIG FOTOCombined 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.
A showcase of exceptional craftsmanship
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.

The flexible and resistant rubber strap with texture in relief reinforces the sporty dimension, with all the comfort of a titanium folding clasp.

With the
“Balancier S²”,
Robert Greubel and
Stephen Forsey
take another step in their exploration of new technical and aesthetic
horizons. Rarely has a watch with a sporting vocation presented such a degree of
craftsmanship in movement and case. An exclusive alliance between
creativity and performance, the
Art of Invention, signed
Greubel Forsey.
