Certina Ds Early Diver - Cross Dial - Black Knight - Automatic - 1960 Rif: AAR00136
Sold
This specific Certina DS “Black Knight” was one of the first dive watches ever made by Certina. This watch is from Certina’ early dive development faze and was made with out a bezel attached to start with in the first productions. As demand for dive watches rapidly grew during the early 1960’ies dive watch with multiple functions such as bezel soon was to become the most common seen dive watch on the scene. The size of the case is 36 mm without the crown. DS stands for “Double Safety”. This was achieved by a floated mounting of the entire movement with an elastic shock absorber ring in addition to the conventional shock absorber (Incabloc). Aside from that, there was an air gap between the dial and case. So the movement could move in all directions. Other features were additional sealings, an extra thick and sheathed Plexiglass, combined with the enhanced caseback. Automatic movement with Caliber 25-651 Original dial and bracelet.
