The Airain Type 21 is inspired by a 1960s vintage model first found at a Sotheby’s auction, which honored the French Ministry of Defence’s 1956 request to upgrade the Type 20 for increased durability and easier maintenance. Both the Type 21 and its predecessor feature a hand-wound column wheel chronograph with a flyback function and countdown bezel. The Type 21 sports a glossy black dial with Grade X1 ‘Old Radium’ lume, proudly showcasing the Airain crown logo and ‘Type 21’ marking. Its slightly larger stainless steel case retains the classic charm while meeting modern standards. Powered by the caliber AM2 from Manufacture AMT in La Chaux-de-Fonds, Switzerland, the Type 21 Re-Edition embodies timeless sophistication and functionality.

The Airain Type 21 stands as a tribute to a 1960s vintage model unearthed at a Sotheby’s auction in 2021. Rooted in the original 1950s designs, both the Type 21 and its sibling, the Type 20, faithfully embody the era’s aesthetics and functionalities. They feature a hand-wound column wheel chronograph with a flyback function and a countdown bezel. Interestingly, the Type 21 emerged from a French Ministry of Defence request in 1956, seeking an upgraded version of the Type 20 with enhanced durability and reduced maintenance requirements.

Displaying a sleek black dial with Grade X1 ‘Old Radium’ lume, the Type 21 proudly bears the Airain crown logo and the distinct ‘Type 21’ marking. Notably, its bezel boasts a luminous triangle at the 12 o’clock mark. While the stainless steel case measures 39.0mm (bezel 39.5mm) — slightly larger than the original — it maintains the classic allure while meeting contemporary standards. The Type 21 Re-Edition is powered by the caliber AM2, meticulously crafted by Manufacture AMT, Sellita’s esteemed division in La Chaux-de-Fonds, Switzerland.
