The Longines Diver watches were inspired by the brand’s commitment to functionality and reliability in underwater exploration, catering to the growing popularity of recreational and professional diving in the mid-20th century. Introduced in the 1950s and 1960s, models like the Longines Nautilus Skin Diver and Legend Diver drew from the technical requirements of divers, featuring water resistance, rotating bezels for tracking dive times, and luminescent markers for visibility in low light. These timepieces reflect Longines’ dedication to precision and adventure, combining robust engineering with timeless design to honor the spirit of exploration both above and below the surface.
