Certina has been dedicated to the demanding art of Swiss watchmaking for over 130 years. The brand is built on high-quality workmanship, modern technologies, attractive designs – and absolute reliability in all the ups and downs of life. This reliability is secured by means of the ultra-robust Double Security (DS) Concept, which since 1959 has provided Certina watches with rugged resistance and water resistance to at least 10 bar (100 meters).
