ISO 6425 standard
Only watches that meet the exacting requirements of the ISO 6425 standard can officially be called diver's watches. With its numerous functions and safety features, this watch is the ideal companion at all kinds of sports events - and its water resistance has been tested for three hours under water.
Powermatic 80 Movement
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...
The glorious past
The historic predecessor and namesake of this watch had the best opportunity to demonstrate its strengths; in 1969, four scientists wore this watch during their two-month research stay at the Tektite I underwater laboratory. They all agreed that the timepiece was an outstanding success!
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.
Partner of the Sea Turtle Conservancy
In 2017, Certina became a proud partner of the Sea Turtle Conservancy. The Florida-based organisation, whose primary aim is to ensure the survival of the sea turtle and conserve its habitats in the Caribbean, was founded in 1959 - the same year that Certina developed the ultra-resistant DS Concept.
Great and beautiful
Watch straps made from #tide ocean material® not only look great and are very robust, they also serve a good cause: The high-quality yarn that makes up this textile strap started its life as plastic waste fished from the oceans.
