Balancier
Greubel Forsey’s "balance-wheel" branch: pieces built around oversized variable-inertia balance wheels visible through dial-side apertures, rather than the inclined tourbillons that anchor the rest of the catalog. The Balancier Convexe S² (titanium, integrated rubber strap, 2021) carries the family into the sport-cased territory the GMT Sport opened up. The Double Balancier carries two coupled balances on the same architecture. The GMT Balancier Convexe adds a three-dimensional rotating world-time globe to the same balance architecture.

Which ref to buy
The Balancier Convexe and Double Balancier represent Greubel Forsey approaching the three-hand watch with their characteristic obsession with regulation precision. The Double Balancier uses two inclined balance wheels to average out position errors across their two planes.
- 1Open
Balancier Convexe: convex sapphire crystal over an inclined balance wheel, GF finishing standards applied to a clean dress brief.
- The case for it:
- The Balancier Convexe is the most approachable Greubel Forsey aesthetically: a dress watch that happens to have an inclined balance wheel visible through a convex crystal. If you want GF finishing and engineering at the "simpler" end of their lineup, this is the entry.
- Consider instead if:
- The Double Balancier is technically more significant. The Convexe is the choice for buyers who want the GF aesthetic without the multi-complication complexity.
- 2Open
Double Balancier: twin inclined balance wheels averaging position errors across two planes, technically the more rigorous regulator.
- The case for it:
- Two inclined balance wheels is the technically correct solution to the positional rate variation problem. The Double Balancier is where Greubel Forsey's engineering argument is strongest.
- Consider instead if:
- The double mechanism adds visual complexity. The Convexe has a cleaner dial statement.
