More than a final edition, this stainless steel interpretation is a statement of purpose – it is the rarest and most exclusive case material in the Atelier’s repertoire. Its presence here is deliberate: to honour the legacy of the Balancier Contemporain with purity, restraint, and resolve.
Compact, yet monumental
When it was introduced, the Balancier Contemporain redefined expectations – delivering the full Greubel Forsey experience in just 39.6mm. This final edition preserves that feat of engineering and design. Under its high-domed sapphire crystal, the gold dial reveals a rich interplay of levels, textures, and finishes.

A sunburst blue hour-ring frames the composition, while a deep blue minute-circle and sectorial indications for the small seconds and power reserve create both contrast and clarity.

A large visual opening draws the eye to the in-house 12.6mm balance wheel, suspended above a flat, black-polished gold plate that provides visual depth and dramatic reflection.

The movement is composed of 256 parts, each hand-finished to the highest standard. The bridges are in nickel silver, frosted and spotted by hand, with perfectly polished bevels and countersinks, straight-grained flanks, and a subtle blue treatment unique to this edition.

The balance wheel bridge is flat black polished steel – one of the most demanding finishes in haute horlogerie – with hand-polished bevels that reflect light beautifully. The balance wheel itself is mounted above a flat black-polished gold plate, a surface so refined it becomes both technical and architectural.
