Certina, the legendary Swiss watch brand, was founded in 1888 in Grenchen by Adolf and Alfred Kurth. The brand officially adopted “Certina” (from the Latin “certus,” meaning “certain”) in 1938.
Certina is most renowned for its groundbreaking “DS” (Double Security) concept, which was first introduced in 1959. The original Certina DS was a revolutionary automatic watch designed to be exceptionally resistant to shocks, water, and pressure. Its innovative construction included a robust case, a free-floating movement within a flexible ring, a reinforced case back, and special gaskets for the crown and stem.
The very first units (as this piece) had dauphine hands and a flat case back without the turtle logo, and the patent application instead of the patent number engraved on the inside of the case back. Until May 1960 when the patent was granted, ‘Patent Pending’ was marked inside the caseback.
Vintage first-generation Certina DS watches are highly valued by collectors for their historical significance, sturdy construction, and their classic yet durable design.

This piece has a steel case with some wear and scratches, and the dial has a uniform patina – please check the pictures. The watch also features a new brown leather strap. It will fit wrists of up to 21 cm. The glass is original (polished) and the crown may be a later replacement.
Water resistance has not been tested, therefore it must be treated as NON-waterproof.
The watch will be delivered in a new padded box as seen in the photos, for a better protection during transportation and for a smart and safe storing once you receive it.

As with any other vintage mechanical watch, exact accuracy cannot be guaranteed, as it depends on many factors, including your kind of use. It has been regulated in different positions to minimize the average time gain/loss. The watch has been serviced in August 2025.
