DS Action Diver 40.5mm | Rewriting the rules of diver's watches

Certina expands its dive watch legacy with a new, in-demand 40.5mm size, completing the DS Action lineup. With its 300m water resistance and ISO 6425:2018 certification, this model meets the highest standards for professional dive watches. The DS Action Diver 40.5 mm also marks a milestone as the first Certina watch to feature the next evolution of the DS system: the “New DS Concept Extreme Shock Resistance”. This technology enables the timepiece to withstand g-forces so extreme that the testing equipment itself reached its limits during trials.
