Founded in Switzerland in 1888, Certina has built an international reputation for producing precise, reliable and robust sports watches. The brand combines Swiss watchmaking expertise with a genuine culture of performance and exploration. Its name comes from the Latin word certus, meaning “assured” or “certain”, reflecting its constant pursuit of reliability. Since 1959, the DS, or Double Security, Concept has reinforced the watches’ resistance to shocks, pressure and external stresses. This construction represents one of the foundations of the professional diving watches developed by Certina. Designed for demanding environments, its aquatic timepieces focus on water resistance, legibility and structural strength. The Powermatic 80 automatic movement also provides a power reserve of up to 80 hours in many models. Certina’s turtle emblem symbolises durability, longevity and the brand’s historic connection with the ocean. Certina notably supports the Sea Turtle Conservancy and uses textile material made from recycled ocean-bound plastic for selected straps. Combining watchmaking heritage, technical innovation and environmental commitment, Certina creates diving watches for professionals and enthusiasts alike.
