The ALT1-B (GMT) Chronograph hails directly from the military. Constructed to withstand the rigours of high altitude or undersea depths, our military watches adorn the wrists of combat personnel worldwide. 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 and bracelet.
