The Altitude Chronograph GMT is Bremont’s ultimate aviation tool watch, combining MB-series durability with chronograph and GMT functionality.

The dial features Super-LumiNova markers, recessed subdials, and a red-tipped GMT hand, with a propeller-inspired seconds subdial nodding to Bremont’s military roots. • Powered by the chronometer certified automatic movement with 25 jewels and a power reserve of up to 62 hours. • Presented on a black leather strap with push button deployment clasp. • Scratch resistant sapphire crystal glass. • 42mm case width. • 100 metre water resistance.
