Greubel Forsey presents the ultimate and conclusive edition of the Balancier Contemporain, forever closing the book on one of the Atelier’s most emblematic calibres.
Encased in a 39.6 mm stainless steel case — a metal reserved for only the rarest of milestones, and used just twice before in Greubel Forsey’s history — this edition is strictly limited to 33 pieces, each scheduled for delivery exclusively in 2025. Once the final piece leaves the Atelier, the Balancier Contemporain calibre will be permanently retired, never to return.
But this is no ordinary swan song. This final edition is a testament in steel — the rarest material in the Maison’s repertoire — chosen with deliberate restraint and reverence. It reflects the spirit of the Balancier Contemporain itself: pure, uncompromising, resolute.
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. On the movement side, a black-polished gold plate is engraved in relief with the fundamental values of Greubel Forsey – invisible to the wearer, yet finished with the same uncompromising care. Olive-domed jewels are set in gold chatons, with hand-polished countersinks that catch the light at just the right angle. Every component, visible or not, is treated with the same reverence – as if each part could stand on its own as a miniature work of art.
This is the last timepiece to carry the Balancier Contemporain calibre – but it is also the first to signal a new direction. With this final edition, Greubel Forsey opens a new chapter focused on small-diameter timepieces. Over the coming years, this creative momentum will continue to build, exploring new dimensions of mechanical expression, proportion, and elegance – all without compromise.
The Balancier Contemporain in stainless steel is a definitive conclusion – and a confident beginning.
