Specialities:

  • 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. Only three years later in 1963 Certina launched a new model this time with a bezel feature as seen in on the also very collectable Certina DS Diver
  • In the middle of the fifties, a team under the guidance of engenieer Philipp Kurth wanted to design a wristwatch as rugged as possible. Through countless experiments they finally developed the construction principle of 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 the movement could move in all directions. Other features were additional sealings, an extra thick and sheathed Plexiglass, combined with the enhanced caseback.

 

 

Certina Echo Winter 1968

 

  • Despite the classical styling with the Bombay band lugs, the watch was very robust. She held out bumps up to 6 meters and was water resistant up to 200 meters. The first watches, which came on market in 1958, had a flat caseback whitout the turtle logo. As movement, the 25-45 was used. Very early specimens still had a evidence to the patent application instead of the patent number engraved on the inseide of the caseback. This patent (346825) was related to the shock mount of the movement and was registered on 8. Mai 1958 by case manufacturer Huguenin Fréres (see patent drawing on the right).
    From the end of 1960, the new calibre 25-65 respectively 25-651 was used and from then on the famous turtle was engraved in the caseback. The manual wind version had a flat, and the automatic version a waved caseback.
  • Special: In the period 1958 – 1968 Certina produced the legendary Certina DS (Double Security) – Only 300.000 were made and this is not only one of the wathces from the very first production af Certina DS but also among one of the few or only Certina DS Certidate with the Calibre 25-661 ever seen up for sale in a perfect condition as this splendid timepiece with date function.
  • Special: Certina DS became legend and easy to recognize with its trademark inprinted on the back-case also know as the famous turtleback.
  • Band: the watch comes with the original and NOS ( new old stock ) Certina DS band and buckle.
