Certina holds a special place in horological history from the early 50s through to the mid 70s. Apart from DS (I will elaborate) there weren’t any standout designs and there were few technological breakthroughs, but the movements were so well finished and strong and the cases were likewise well constructed that (I’ve said it before) the brand was a favorite among watchmakers.
Having said all that, Certina in the mid fifties, set out to design a wristwatch as rugged as possible. The result was the DS models. 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, in the case of a severe shock, the movement could move in all directions and sestain no damage. Other features were additional sealings, an extra thick and sheathed plexiglass, combined with the enhanced caseback.
The DS was released in 1958 and used this 25-36 manual wind movement only until 1960. The first models had a plain back but from 1960, the famous turtle was engraved on the back. So this watch, with the turtle, must be a 1960 model.
I have always been a great fan of Certina. And of all the Certinas, the DS is the most desireable. I discovered that they where hard to find in the condition that I consisder acceptable and it took years. But, finally, here it is, slightly aged dial, scratched case and apart from the band, all original. Signed four times; dial, movement, crown and back.
The Certina DS is a very special watch.
