Greubel Forsey · Balancier Convexe S² Titanium 41.5 mm
The model in detail
Your eye immediately drops to the inclined balance in the Balancier Convexe S². Set at 30°, it opens the movement vertically instead of arranging everything on one plane. This is not a tourbillon. The balance oscillates in place; there is no rotating carriage changing its orientation.
The model is distinctive because its construction follows a consistent idea. Both front and back of the case are curved. The exposed levels of the movement continue that geometry. The case becomes part of the composition rather than a frame around a flat dial. The watch invites a side view as much as a frontal one.

It displays time, small seconds and reserve; complexity resides in the construction of the basic mechanism itself. Inclination alone, however, does not prove superior accuracy: that requires comparable measurements.
Convexe matters as an attempt to give high watchmaking spatial depth without requiring a tourbillon. A 41.5 mm diameter sounds compact on paper, but the 14.8 mm height changes expectations about fit. This is an object for someone who enjoys movement architecture and how space is organised, beyond the number of functions on a specification sheet.
