Excellence far beyond the surface

Marine environments bring out the most stringent best. In 1961, the famous first version of the Certina Blue Ribbon became the most resistant timepiece in the world.
The new Certina DS Blue Ribbon line, styled along an extreme-sport paradigm, was created for underwater sports enthusiasts who refuse all compromises. A DS+ system, boldly marked in luminescent glyphs upon its crown, an over-pressure release valve, a unidirectional rotating bezel, water resistance to 330 m and a solid steel- or rubber bracelet with diving extension, is all you will need to bring you to great depths, boldly, reliably and very precisely.
