The **New GMT Balancier Convexe** 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.
