The ALT1-B (GMT) Chronograph hails directly from the military. The design closely mirrors the watch Bremont delivered to elite B2 ‘Stealth Bomber’ Aircrew in 2012. Based on the ALT1-Z, it incorporates advanced elements of the Bremont chronograph range, including a modified BE-54E movement, Trip-Tick® case, Roto-Click® internal bezel, and black DLC case.
