Founded in 1969, Le Forban Sécurité Mer is a French professional dive watch brand among the rare ones to have equipped the French Navy and Maritime Patrol Pilots (PATMAR) in the 1970s-80s. Its timepieces were designed as genuine underwater work instruments, robust, precise, and rigorously watertight to withstand extreme deep-sea conditions. After a 30-year eclipse, the brand was revived in 2019, faithful to its original tool-watch professional DNA. Today, it offers a range of neo-vintage automatic watches assembled, tested, and adjusted in Rennes, Brittany, by a team of French horologists. The La Malouine, La Brestoise, and La Rochelaise collections continue this heritage of professional dive watches with watertight, repairable, durable, and accessible timepieces. Le Forban Sécurité Mer is French professional diving: no compromises, with character and maritime authenticity.
