Certina loves turtles. The 136-year-old (underrated) Swiss brand, best known for its signature “Double Security” or "DS" O-ring gasket system, started using a turtle as one of its logos in 1959 to symbolize the waterproofness of their watches. Coincidentally, 1959 also marked the establishment of the Sea Turtle Conservancy (STC), an international non-profit that’s now the world’s oldest sea turtle research and conservation group. This watch a [recreation of a watch](https://thevintageur.com/wp-content/uploads/2017/04/DSC_1665-500x500.jpg) that first surfaced in their line up in the 1970s. That original diver was a rare example of a commercial diver which could reach 1000M depths, and now it’s back as the Certina DS Super PH1000M. This "STC" version introduces the beautiful blue colorway, and a collaboration with the non-profit Sea Turtle Conservancy. My particular example is AD-bought (from Teddy Bulbasaur) and has over a year of warranty remaining. Here are the quick specs.
