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.

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.
