Double Balancier Convexe

The Double Balancier Convexe slips more easily under a fitted sleeve, or can be worn casually on a bare wrist. Depending on their preference, collectors can hide or reveal the mechanics of their visible movement to their liking, without appearing ostentatious.

The finish of the piece has been designed with this aspect in mind. The case is made of natural titanium in a silky, luminous grey. The polished bezel features subtle satin finishes that add shine and elegance through the play of light so characteristic of the Convexe line. The lettering on the barrel cover blends seamlessly into the redesigned case, creating an exclusive dynamic that evokes its rotation, offering 72 hours of guaranteed power reserve.

The plate, also in titanium, is grained — discerning collectors will note the ambition of this finish, titanium being a hard natural material and therefore by definition the most difficult to grind. The same high standards apply to the bridge of each balance wheel, whose bevels are also polished by hand — a particularly meticulous exercise requiring exceptional expertise, especially when the bridge in question is openworked and flat black-polished.

The balance wheels remain linked by the spherical differential, visible between 6 and 7 o'clock. In 4-minute sequences, it establishes the best running average to meet the performance, precision and reliability requirements that Greubel Forsey imposes on all its timepieces.
