The Airain Type 21 is inspired by a 1960s vintage model first found at a Sotheby's auction, which honored the French Ministry of Defense's 1956 request to upgrade the Type 20 for increased durability and easier maintenance. The Type 21 sports a glossy black dial with Grade X1 ‘Old Radium’ Lume, proudly showcasing the Airain crown logo and ‘Type 21’ marking. The Airain Type 21 is powered by the caliber AM2, a hand-wound column wheel chronograph movement. This movement features a flyback function, allowing pilots to quickly reset the chronograph and start a new timing event without delay.
