Founded in 1924 in Lengnau, at the heart of Switzerland’s watchmaking region, DELMA creates Swiss Made watches focused on precision, durability and innovation. As a family-owned company, the brand places quality at the centre of its philosophy and develops every watch from the initial sketch through technical drawings, 3D modelling and final prototyping. DELMA’s diving heritage began in 1969 with the Periscope, its first wristwatch to offer increased water resistance. In 1975, the brand strengthened its professional diving expertise with the launch of the Shell Star and Quattro. These pioneering models have continued to evolve and remain important members of DELMA’s collection today. DELMA now offers a dedicated diving range including the Blue Shark, Quattro, Shell Star, Cayman, Commodore and Santiago. The brand combines Swiss watchmaking tradition, technical engineering and robust instruments designed for demanding underwater environments.
