The Certina DS line of waterproof watches was designed with a thick shock absorbing rubber case holder between the movement and the case to provide an extra level of shock protection — thus the “Double Security” nomenclature. The present example is the second series of DS divers with interesting crosshair dial accented by Arabic numerals. The movement is Certina’s own design and the original bracelet is from Gay Freres. The bezel insert has an attractive brown patina.
