Bremont Altitude Perpetual Calendar GMT

The Altitude Perpetual Calendar GMT sits at the top of Bremont's Altitude collection and is limited to 50 pieces. It combines two complications through a module developed with the Geneva atelier Agenhor on a hand-wound BHC9192-MH base: a rotating globe at 12 o'clock for a second time zone, and sub-dials at 3, 6 and 9 for the month and leap year, the date and running seconds. Everything is set through a mono-pusher built into the crown and discreet correctors. The case is Bremont's Trip-Tick construction in Grade 2 titanium, 42 mm across, 12.65 mm thick and 49.62 mm lug to lug, with an Air Force Blue dial and case barrel under a glass-box sapphire crystal. It comes on a titanium bracelet or blue leather at $38,450.
