The New GMT Balancier Convexe (or: GMT Balancier Convexe plus 7 more) is a wristwatch by Greubel Forsey.

This new creation is a complete reinterpretation of the predecessor, while refining its proportions and mechanical layout.

The Convexe case, still sculpted in titanium, is now more compact at 42.90 mm at the caseband for improved wearability.
The movement now contains 496 components, 73 more than its predecessor, attesting to a re-engineering of the calibre to accommodate new displays and improved chronometric performance.
A new 72-hour power reserve indicator is seamlessly integrated into the dial, bringing added functionality without disrupting the visual harmony.
