The striking DS Super PH500M is sure to attract attention thanks to its retro style and orange dial. A number of functional features such as its magnetic field-resistant NivachronTM balance spring and water resistance of up to 500 m make this diver's watch the ideal companion on every journey – even underwater. The logo of the German diving association VDST has been immortalised on the case back of the DS Super PH500M. Certina hasn't merely alluded to their love of the underwater world with this embellishment – when developing the watch, the Swiss watchmaker called upon the expertise of these passionate divers. Thanks to the innovative design behind the divers' strap extension, the watch can be comfortably worn over a wetsuit too. The beating heart of this model is a Powermatic calibre with an entirely new balance spring made of Nivachron™. This innovative material has been developed to increase resistance to magnetic fields. The Swiss-Made balance spring has a titanium base and is therefore exceptionally resistant to temperature variations and incredibly shock-resistant.
