Certina DS Action watches belong to the Aqua model line, which, as the name suggests, is intended for water lovers. They will definitelly enjoy the 200M water resistance that is provided by a set of measures increasing the DS Concept durability, screw-down crown and screw-down caseback.
The watch glass is sapphire with a one-sided anti-reflective layer that reflects only less than 10% of incident light, so the watch is easier to read even in direct sunlight. The watch is powered by a Swiss quartz movement ETA with Precidrive technology, thanks to which the watch ticks with an accuracy of +/- 10 seconds / year, which is 8 - 10 times more accurate than conventional quartz movements. In addition, the watch has an EOL (end of life) function, which alerts its owner to a low battery by the second hand starting to "bounce" at two-second intervals. The watch also has a COSC precision certificate issued by the Swiss Institute and can thus be proudly called a chronometer. In addition, Certina extends the warranty period for these watches to 3 years.
