Certina DS SUPER PH2000 Built for the deep and engineered for the extreme, the Certina DS SUPER PH2000 is a professional dive watch that goes where others can't. Its lightweight titanium case withstands pressures up to 200 bar (2,000 m / 6,562 ft), backed by the DS Concept extreme shock resistance system. At its heart beats the ETA Powermatic 80.611 — a Swiss automatic movement with up to 80 hours of power reserve and a Nivachron™ balance spring for outstanding resistance to magnetism and temperature changes. The 43 mm titanium case (16 mm thick) features a screwed crown and caseback, a rotating ceramic bezel with Super-LumiNova, and a sapphire crystal with anti-reflective coating. The black dial with date display remains legible in any light. A titanium bracelet with quick-release system and diver extension buckle completes the package. Delivered in the original Certina box with manual and international two-year warranty. Swiss Made.
