DS-1 Big Date

The rounded dial is reminiscent of watches from the 1960s. A 'fade' effect and sunray finish enhance the intense green tones and give the watch a real sense of depth. A large date display window at 6 o'clock, together with finely faceted wedge-shaped indices and long hands, guarantee easy readability.

The big date, also called panorama date, is a particularly popular display showing the date in an enlarged date window by means of two discs placed either next to each other or overlapping. This elaborate display allows the date to be read quickly and easily.

Power reserve is the time a fully wound mechanical watch runs until it stops - usually between 38 and 42 hours. The Powermatic 80 calibre makes a power reserve of up to 80 hours possible! So you can leave this watch for up to three days before having to set it anew - if you can do without it for that long...

Certina affords great views of this mechanical timepiece: the case back has a robust watch glass through which to admire the mechanism. The delicately constructed rotor that reliably ensures the provision of energy in all automatic watches is clearly displayed.

The beating heart of this model is a Powermatic calibre with an entirely new balance spring made of Nivachron(TM). 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.
