The ultimate tool watch from Certina. The DS stands for “dual shock protection”, the inner rubber cushion that protects the movement and the inca shock that protects the balance staff. This 1965 example has an amazing shiny patinated dial with excellent original luminous compound and the heavy duty machined Turtle case back. Fantastic in-house calibre 25-65 Automatic.

The case is in unpolished original condition. The movement is in excellent condition service by me in November 2020. See the service gallery here. Original signed crown and NOS certina crystal.
