The Airain Sous-Marine Re-Edition DNA Strand Ref. 524.437B draws directly from the original 1962 Sous-Marine, staying true to its vintage roots while incorporating modern build quality and reliability. Powered by the Swiss-made AM5 automatic calibre (based on the La Joux-Perret G100), it offers a 68-hour power reserve, smooth tungsten rotor, and refined finishing with Geneva stripes and blued screws.
