With its latest timepiece, Swiss watch brand Certina reaffirms its unwavering passion for the depths of the oceans. The DS SUPER PH1000M first appeared in 1970, causing a sensation both above and below the water. Today, that early model is succeeded by not one but two variants: a limited edition of 1000 pieces featuring a bright orange dial, plus an unlimited version in black. The distinctive wristwatches are powered by a cutting-edge automatic calibre with an 80-hour power reserve and NivachronTM balance spring.
