Certina completes the DS Action lineup with the Diver 40.5mm

ertina 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.

With precision and endurance, Certina watches have proven themselves in the most demanding environments, where the pressure of the ocean is matched only by the thrill of exploration. From the 1960s to the 1970s, extreme underwater missions like Sealab II and Tektite I & II tested Certina’s legendary reliability, solidifying its reputation as the maker of professional-grade diving instruments.

At the heart of this “certainty” lies Certina’s groundbreaking Double Security (DS) system, which revolutionised shock and water resistance when it was introduced in 1959. This innovation set the standard for durability and trust.

Today, Certina continues to redefine limits with the “New DS Concept Extreme Shock Resistance”: the next evolution of the iconic DS system, engineered for greater resilience and performance, far exceeding the standards of ISO 1413.

Like Certina’s symbolic turtle emblem, the “New DS Concept Extreme Shock Resistance” brings additional durability to the DS Action Diver 40.5mm’s resistance. In addition to the traditional DS system, three new features improve shock resistance by securing the movement within the case, reinforcing the dial’s stability and strengthening the watch glass.

Two stainless steel models: black or white dials, with matching ceramic bezels and metal bracelets. One titanium edition: a blue dial and bezel, engineered for lightweight resilience. One NATO strap edition: the black dial model pairs with a striped black and beige NATO wristband, blending functionality with style.

The DS Action Diver 40.5mm also features:

High-performance ceramic bezel: scratch-resistant, robust and built to last.
300m water resistance: ready for any adventure, above or below the surface.
ISO 6425:2018 certification: meeting the highest standards for professional dive watches.
Automatic movement Powermatic 80: offering an impressive 80-hour power reserve & the Nivachron™ balance spring.
Super-LumiNova coated hands and dial: build for visibility in any light.

From ocean’s depths to the unpredictability of daily life, the DS Action Diver 40.5mm offers a sense of certainty.
