The Certina DS Action Lady Quartz Precidrive COSC Chronometer watch belongs to the Aqua model line, which, as the name suggests, is intended for water lovers. They will definitelly enjoy the above-standard 300M water resistance, that is provided by a set of measures increasing the DS Concept durability, screw-down crown and screw-down caseback.
The bezel of the watch is one-way rotatable, the watch glass is sapphire with double-sided anti-reflective coating that reflects only 3% of incident light. The watch is therefore perfectly legible 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.
