New Size, Same Dive-Ready Confidence

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”.

Introducing the New DS Concept: Extreme Shock Resistance

This launch also marks a major technical milestone — the debut of Certina’s New DS Concept Extreme Shock Resistance. Evolved from the original Double Security (DS) system first introduced in 1959, this updated design features:

  • Reinforced movement housing
  • Stabilised dial construction
  • Strengthened watch glass

The result? Unprecedented resistance to shock and g-forces, so extreme they exceeded the limits of Certina’s own testing equipment.

Every model features a scratch-resistant ceramic bezel, Super-LumiNova® hands and markers, and the automatic Powermatic 80 movement with 80-hour power reserve and Nivachron™ balance spring for superior magnetic resistance.


Built to Withstand. Designed to Endure.

From undersea missions in the 1960s to modern engineering breakthroughs, Certina’s dive watches have always stood for reliability under pressure. With the DS Action Diver 40.5mm, that legacy continues — bringing together Swiss-made precision, bold design, and the strength to thrive in the unexpected.
