Founded in Lengnau (BE) in 1924, DELMA is an independent and family-owned Swiss watch brand specializing in the design and manufacture of sports watches.

In 1969 DELMA launched their first divers’ watch, the Periscope, and started to develop a wide range of marine watches.

In 2019 to celebrate its 95th anniversary and 50 years of divers’ watches, DELMA presented in Basel the Blue Shark III, a model water resistant to 4000 meters.
