Bremont Airco watches

The Bremont Airco is named after the Aircraft Manufacturing Company Limited, one of Britain's first military aircraft manufacturers. Bremont announced the first two models, the Mach 1 and Mach 2, in March 2017 at its own London event, and added the Mach 3 in 2018, the year that marked 100 years of British military aviation.

All three use the same Trip-Tick case: 40 mm across and 12.5 mm thick including the domed sapphire crystal, in hardened steel with a DLC-treated middle barrel, a screw-down crown, a sapphire display back and 100 m of water resistance. Inside is the BE-92AE, a COSC-certified automatic that Bremont prepares from the ETA 2892. It beats at 4 Hz and runs for at least 38 hours.

What separates them is the dial and the finish. The Mach 1 is the field watch of the three: a matte dial with a railway minute track, very little text, the date at 3 o'clock and a red-orange seconds hand, in a satin case with a polished bevel. The MACH 1/BK has a black dial; the white MACH 1/WH, added in 2018, has a contrasting red seconds hand. The Mach 2 is what Bremont calls an officer's dress watch, with a polished case, an opaline metal dial with polished Arabic numerals, polished hands and the date moved to 6 o'clock. The MACH 2/AN was joined in 2018 by the white MACH 2/WH.

The Mach 3 (MACH 3/BL) borrows from both. Its opaline dial is in Royal Air Force blue and uses baton indexes instead of Arabic numerals, with the Mach 2's date at 6 o'clock and the Mach 1's satin-brushed case.
