Certina timepieces are designed to withstand extreme conditions. To ensure this and prove it time and again, the watches have already accompanied expeditions to the highest mountains or the bottom of the ocean, supported scientists for months under water and overcame a difference in altitude of 1,000 meters during one of the most daring ski descents of all time by extreme athlete Yūichirō Miura. Certina was also active in motorsports, appearing for many years as a sponsor in Formula 1, motorcycle racing, and several GT series - a passion that is still reflected today in the DS Podium collection with its many chronographs. Certina is also involved in padel tennis and the biathlon, and a Certina DS DiaMaster has also been worn on the wrist of the famous heavyweight boxer Muhammad Ali.
