Bremont Watch Altitude Chronograph GMT Black Nato ALT42-CHR-G-SS-BK-N-S. Since Bremont was founded in 2002, the drama and wonder of aviation have been at the heart of its story, and of its products. Its pilot’s watches, robustly engineered and rooted in aviation heritage, have earned the trust of military and civilian fliers, adventurers, collectors and enthusiasts. Purposeful, bold, and deeply rooted in aviation, watches combining chronograph and GMT functionality have long been a staple of Bremont’s lineup, as well as playing a key role in some of Bremont’s most successful military collaborations. As such, it was always going to be an essential part of the new Altitude collection. For the 42mm Altitude Chronograph GMT, despite the functional complexity born from two significant complications and multiple read-outs, legibility and ease of use remain paramount. Combined with the hardiness and dependability that unites all the Altitude watches, this makes for a mission-ready timepiece that’s purpose built for exploration, travel and demanding environments.
