    Greubel Forsey unveils a new interpretation of its GMT Balancier Convexe – more refined, more wearable, and more complete than ever before.  With a more compact case, an integrated power reserve display, and even more technical and aesthetic finesse, it becomes the purest expression of our GMT complication to date – and the only GMT model in our current collection.

    The Terrestrial globe remains the central element of this creation – a miniature Earth rotating in real time over 24 hours, nestled within an amphitheatre-like architecture. Flush with the sapphire crystal, it is surrounded by multiple layers of timekeeping indications: local time, universal time, a second time zone, as well as the distinction between day and night.

    – The Convexe case, still sculpted in titanium, is now more compact at 42.90 mm at the caseband for improved wearability.
    – A new 72-hour power reserve indicator is seamlessly integrated into the dial, bringing added functionality without disrupting the visual harmony.

    On the caseback, a sapphire disc engraved with 24 cities reflects both universal time and summer/winter time, with La Chaux-de-Fonds replacing Paris – a subtle but meaningful shift.

    This new GMT Balancier Convexe will be made in a strictly limited series of 22 timepieces.
