A Dive Watch from the 60’s Reimagined: Meet the Airain Sous-Marine

Getting your Trinity Audio player ready...

Airain has made waves in the watchmaking industry, especially after its merger into Compagnie des Montres Lebois & Co (CDMLEC), steered by the visionary Dutchman, Tom van Wijlick. The brand, closely linked with Lebois & Co, has been on a revival spree, bringing classic timepieces back to life. Recently, the much-acclaimed Airain Type 20 pilot’s chronograph made a comeback, charming enthusiasts with its authentic reissue. Now, Airain is set to make headlines again with the relaunch of another timeless piece – the Airain Sous-Marine.

Airain Sous-Marine DNA Flat

The Airain Sous-Marine, a flagship model from the brand’s storied past, is making a return, much to the delight of vintage diving watch aficionados. Characterized by its bold 1960s design, the Sous-Marine stood out with its hefty case, black unidirectional bezel, matte dial, and notably large numerals. Its most distinctive feature, however, was its unique central seconds hand, designed to resemble a DNA strand – a quirky detail that set it apart in the crowded field of dive watches.

Airain Sous-Marine Crown System

The design process of the Sous-Marine reissue has been a collaborative journey, involving four phases and incorporating public input on various design elements, such as the crystal type and the style of the second hand. Despite some changes necessitated during the technical development phase, such as replacing the voted acrylic crystal with a more durable sapphire one, the essence of the Sous-Marine remains true to its roots. This includes the retention of the original’s Parmentier crown, vital for its 200-meter water resistance.

Airain Sous-Marine Dial

The reimagined Sous-Marine is faithful to its predecessors in terms of aesthetics as well, reflecting the distinctive dive watch style of its era. It boasts a 37.5mm stainless steel case, with a slightly larger bezel and a slim profile. The dial, available in a variety of colors including deep blue and tropical green, maintains excellent readability with large, beige-colored numerals.

Airain Sous-Marine Case Back

At the heart of the new Sous-Marine beats the modern La-Joux Perret G100 movement, a significant upgrade that offers a 68-hour power reserve and is housed behind an engraved solid caseback. The watch also features the reintroduced Fixoflex bracelet, alongside a Tropic-style FKM rubber strap, offering versatility and a nod to its historic counterpart.
