Greubel Forsey is testing your patience when you want the Greubel Forsey Double Balancier Convexe 42.5 mm: if you order today it will be delivered between now and 2026. But when you finally get it, you’ll have a very special, and big, master piece.

Although not small, a 42.5-millimeter case, in titanium, is not that big. But the three-dimensional, variable geometry-shaped and hand-polished bezel measures 44.4 millimeters. The curved synthetic sapphire crystal on the front plus on the back makes the watch 14.35 millimeters thick, so for sure it’s a remarkable time piece.

The Greubel Forsey Double Balancier Convexe 42.5 mm has a power reserve of 72 hours

And it’s remarkable on the inside too. The main plate and bridges are from titanium, which is frosted with polished bevelling and countersinks and a grey treatment. All to be admired on the front of the watch. And it provides a great contrast with the dial part, as the watch is half open-worked and half fitted with a dial. On which is the power reserve indicator.

There are two inclined balance wheels that are connected by a constant spherical differential, which you can see between 6 and 7 o’clock. In 4-minute sequences, it should give more precision and reliability. The power reserve of 72 hours comes from two coaxial series-coupled fast-rotating barrels (1 turn in 3.2 hours), one of which is equipped with a slipping spring to avoid excess tension.

The Double Balancier Convexe 42.5 mm is limited to 88 pieces.
