Since 1888, the Certina brand has united outstanding quality standards, technical expertise and exceptional resilience. The Certina DS (Double Security) concept establishes the standard for all timepieces: Water-resistant to 10 bar (100 m), anti-reflective sapphire crystal and extreme precision thanks to the Precidrivequartz movement. Thanks to the Powermatic 80 movement, selected Certina self-winding timepieces have a power reserve of up to 80 hours. These high standards and a love of detail are key components of the brand's philosophy and are what makes a Certina timepiece truly unique. Swiss Made. The Heritage collection presents unmistakable models that evoke and pay homage to the most important timepieces from Certina's history.
