Greubel Forsey has long been known for its extra-large watches with three-dimensional, highly complicated movements — never for compactness or wearability. That changed in recent years with the arrival of the Balancier Convexe S2, a comparatively restrained 41.5 mm time-only watch. For many, it represents the most distilled expression of the brand’s values, as well as an entry point thanks to its relative accessibility. But this chapter is now coming to an end. Greubel Forsey has announced two final versions of the Balancier Convexe S2, each limited to 10 pieces, marking the end of the series before it is discontinued.

Minimal but not simple

It’s unfortunate to bid farewell to the Balancier Convexe S2, because it’s a genuinely compelling watch. It stands as a textbook example of an entry-level piece that remains deeply attractive. No corners are cut — the S2 still carries Greubel Forsey’s creative and inventive approach to chronometric timekeeping, most notably in its balance wheel inclined at 30 degrees to optimise its position on the wrist.

And it’s not just the balance that stands out. It is fully visible on the front, accompanied by several other components and bridges that are proudly put on display. This reflects another defining trait of Greubel Forsey: a three-dimensional movement architecture that feels at once traditional and contemporary, yet expressed here in a more restrained, minimalist manner. It is also a feat to have so many different elements, including the balance assembly, small seconds, power reserve indicator, barrel and bridges, all on the front without looking crowded.

The attention to detail is equally evident, down to the balance wheel itself, with its beautifully executed recessed slots for the variable weights. Every part is carefully designed and finished, upholding Greubel Forsey’s exceptionally high standards, even among independent watchmakers.

All of this is housed in a cleverly curved 41.5 mm case that hugs the wrist comfortably. What’s not to love?

Final edition in ceramic

The final edition retains all the strengths of the previous Balancier Convexe S2, but it looks quite different at a glance, largely due to the introduction of new palettes.

Two versions are being launched, both featuring ceramic as the main case material. While it is not the first time the brand has used ceramic, it remains a rare choice for Greubel Forsey, making it especially fitting for a send-off edition. Even more notable is how it is applied. The first version combines black ceramic with red gold, creating a rich and striking two-tone pairing that feels new for the brand, excluding any private commissions.

The second version is rendered entirely in white ceramic, paired with a white strap and dial. The result is an all-white palette that feels distinctly futuristic and perfectly in tune with the brand’s three-dimensional, contemporary movement design. It is also a colour direction rarely explored by Greubel Forsey. While not entirely unprecedented (there was a Double Tourbillon limited to five pieces), it remains a special and uncommon expression.
