Airain has shared details regarding its corporate structure and its relationship with its sister brand, Lebois & Co. Both brands are owned by the parent company Compagnie des Montres Lebois et Cie (CDMLEC). Airain was originally founded in 1934 and continues to focus on its horological heritage and precision timekeeping under this unified family of brands. Lebois & Co, which was also established in 1934, serves as the sibling brand within the group. While the brand was dormant for several decades, it was successfully revived in 2014, an event that sparked the broader revival of the CDMLEC portfolio. The parent company's mission is to preserve the watchmaking history and craftsmanship associated with both nameplates for future generations.
