Bremont Watch Airco Mach 1 Nato AIRCO MACH 1/BK/R BR.163.2067. This Bremont Airco Mach 1 Nato watch is named after the Aircraft Manufacturing Company Limited, one of the very first manufacturers of British military aircrafts. From the very beginning, Bremont has had a strong association with aviation since founders and brothers Nick and Giles English both grew up flying and building aeroplanes. The exquisite design of the Airco Mach 1 watches combine the passion and expertise of the brothers and their appreciation for beautifully engineered timepieces. Designed to be both durable and accurate, this Bremont Airco Mach 1 watch has been crafted from the hardened stainless steel of Bremont Trip Tick construction with a scratch resistant DLC treated barrel. Within the 40mm case is the chronometer certified BE-92AE automatic movement that is fitted with a stunning Bremont decorated rotor that can be watched through the open case back. The black metal dial is truly striking and has an opalin matt finish with Superluminova coated numerals and markers as well as nickel satin hands. To complete the Airco Mach 1 watch, a NATO style strap and stainless steel pin buckle is added.
