The 40mm Airco Mach 1 Jet infuses an element of edge to this timeless classic with a new DLC (Diamond-Like Carbon) finish and features a contrasting steel crown, case back and pin buckle. The black dial is elegantly matched with white Arabic numerals and hands inlaid with green Super- LumiNova® for increased legibility. The chronometer rated Airco Mach 1 Jet is made from Bremont’s signature Trip-Tick® case construction and incorporates an open case back through which the BE-92AV mechanical movement can be seen.
