The Certina DS Action Diver 40.5mm Titanium does just that—delivering Swiss precision, rugged capability, and surprising comfort in one sleek, modern package.
But this isn’t just another dive watch. It marks a milestone as the first model to introduce Certina’s next evolution in toughness: the “New DS Concept Extreme Shock Resistance”. This system elevates the already-famous DS (Double Security) concept, making this watch tougher, more impact-resistant, and better prepared for whatever life—or the ocean—throws at it.
1. Sapphire crystal or domed sapphire crystal, extremely scratch-resistant
2. O-ring seal on the setting stem
3. Utra-thin seal dial support
4. Screwed movement holder
5. Reinforced case back
The most striking feature of this model is its material: titanium. Lighter than steel by almost half, yet exceptionally strong, titanium makes this watch incredibly comfortable to wear day after day. Whether you’re diving, climbing, or sitting at your desk, this lightweight resilience matters—reducing wrist fatigue while maintaining unbeatable durability.
Titanium is also hypoallergenic and resists corrosion—even from saltwater—which makes it ideal for professional divers and those who demand the best from their gear.
The DS Action Diver 40.5mm Titanium is not only built for toughness—it’s ISO 6425:2018 certified, meeting the most stringent international standards for dive watches. With a 300-metre water resistance rating, this timepiece is ready for serious underwater adventures, offering security, reliability, and performance where it matters most.
Certina pairs the lightweight titanium case with a scratch-resistant ceramic bezel, fired at over 900°C for unbeatable hardness and colour depth. This ceramic won’t fade or dull over time, maintaining its deep blue hue and polished finish even after years of wear. It’s also hypoallergenic—perfect for those with sensitive skin.
No professional diver's watch would be complete without sapphire crystal, and this model is no exception. Certina’s sapphire is forged at over 2000°C from aluminium oxide, resulting in a material that is almost entirely scratch-proof, highly transparent, and exceptionally shock-resistant. This ensures that the dial remains perfectly visible and well-protected in any environment.
Whether you’re exploring the depths or checking the time on a late train, visibility is essential. The DS Action Diver 40.5mm Titanium uses Super-LumiNova® BG W9, which emits a clean, blue glow after exposure to light. This coating is applied to the hands, indices, and bezel markers—ensuring outstanding legibility even in total darkness. Best of all, it’s completely safe and recharges endlessly under any light source.
The true highlight of this model, however, is the debut of Certina’s New DS Concept Extreme Shock Resistance—a significant advancement in watch durability. Developed through cutting-edge research and rigorous testing, this system introduces three key enhancements:
Ultra-Thin Metal Plate: Positioned between the dial and movement to prevent distortion or displacement from impact.
Ring-Nut Secured Movement: The movement is screwed into the case with a thin, ring-shaped nut for exceptional vibration resistance.
Reinforced Domed Sapphire Crystal: Designed to distribute shocks evenly, reducing the risk of cracking.
Together, these improvements make the watch exceptionally robust—even under conditions that far exceed normal everyday shocks or sudden impacts. Whether dropped, knocked, or jolted, this timepiece is built to endure.
Despite its professional-grade dive features, the DS Action Diver 40.5mm Titanium isn’t limited to ocean adventures. Its lightweight comfort, sleek blue ceramic bezel, and clean, modern aesthetic make it just as suited to the city as to the sea. It’s a timepiece that looks sharp with a suit yet is built tough enough for the trail or the reef.
