Launched in 2025, the Certina DS Action Diver features a compact 38mm stainless steel case with a thickness of 13.22mm, representing a new iteration in the brand's line of professional dive watches. This model is equipped with a unidirectional ceramic bezel and is designed to withstand water pressure up to 300 meters, compliant with ISO 6425:2018 standards. Its external features include a securely screwed crown and a domed sapphire crystal treated with a single-sided anti-reflective coating.

The black dial prioritizes visibility with applied hour markers and hands enhanced with Super-LumiNova, alongside a date window positioned at 3 o'clock. The ceramic bezel is marked with a 60-minute diving scale for convenience. At the heart of this watch lies the automatic ETA Powermatic 80.611 movement, which boasts an impressive power reserve of around 80 hours and uses a Nivachron balance spring to improve its resistance to magnetic fields and ensure consistent accuracy. Furthermore, this reference showcases Certina's innovative DS Concept Extreme Shock Resistance system, aligning with the brand's commitment to its "Double Security" philosophy, making the DS Action Diver 38mm a practical and stylish choice for modern divers.
