The watches of the Aqua collection are built for life in and around water. Take the DS Action Diver Powermatic 80, for instance. This classic diving watch is water-resistant to 300 m (30 bar, 984 ft), has a unidirectional diving bezel, and offers optimal readability under all lighting conditions thanks to a generous coating of luminous material on its hands and indices. What's more, the Powermatic 80 caliber provides this timepiece with an 80-hour power reserve and a date display at 3 o'clock.
Certina offers this 43-mm stainless steel watch with a black, blue, or green dial and bezel inlay. You can also choose between a stainless steel bracelet or rubber strap. Prices vary by model and range from 690 to 780 USD. The titanium edition with a gray dial costs slightly more at about 980 USD.
If you're looking for a watch that combines the robustness of a diving watch with the aesthetics of a dress watch, you may enjoy the DS Action Fixed Bezel. Instead of a diving bezel, this model features a stationary bezel in polished stainless steel, which lends it a particularly elegant feel. The inner workings are also different from your average diving watch. Certina equips this watch with the high-precision ETA Precidrive caliber F07.412. This quartz movement is COSC-certified chronometer, meaning it is eight to ten times more precise than conventional quartz movements.
The DS Action is available with a black, blue, gray, or silver sunburst dial and demands around 450 USD on a leather strap or stainless steel bracelet. Other variations include titanium timepieces and two-tone models with a rose gold PVD-coated bezel. Two-tone watches change hands for about 440 USD, while the DC Action Fixed Bezel in titanium requires an investment of approximately 560 USD.
Two other interesting Aqua models are the DS Action GMT Powermatic 80 and DS Action Day-Date Powermatic 80. Both get their power from automatic Powermatic calibers. The DS Action GMT can display the time in two time zones at once, and the DC Action Day-Date has a day-date display at 3 o'clock. Plan to spend around 890 USD on the GMT edition and 670 USD on the day-date model.
Certina Sport
High-precision chronographs make up a majority of the Sport collection. Models like the DS Podium Chronograph 1/100 sec and DS-2 Chronograph 1/100 sec are able to measure periods of time to within a hundredth of a second. This is thanks to a quartz ETA Precidrive movement. Certina uses different versions of this caliber throughout the collection, including ones with a flyback function, lap timer, or second time zone. The Precidrive movement found in three-hand models is even chronometer certified.
In terms of design, the DS Podium and DS-2 series have very little in common. Podium watches have clear and strong ties to motorsport and were inspired by the dashboard displays found in race cars. On the other hand, DS-2 models transform a classic timepiece from the 1960s into a modern wristwatch.
Both series occupy a similar price range. Prices for Podium or DS-2 watches range from 440 USD for a three-hand timepiece to 960 USD for a chronograph.
The DS Eagle Chronograph stands out within the Sport collection. It has a decidedly modern design with an integrated rubber strap and a case protector that mimics the look of a motorcycle's cooling fins. Furthermore, this watch comes with the automatic ETA chronograph caliber C01.211. This movement is a modified Lemania 5100. It comes with a synthetic escapement and a 45-hour power reserve. Be sure to have around 1,900 USD on hand for this 45.6-mm chronograph.
