Certina is a watchmaking brand founded in 1888 that has earned its place through refined collections. Its timepieces combine contemporary technology, striking design, and unmatched reliability. The brand is known for innovations such as the Double Security (DS) concept, which ensures superior resistance. Its craftsmanship and expertise are the perfect embodiment of Swiss watchmaking excellence. Today, with great pride, it unveils this stunning DS Action Chrono C0328271104100 - a watch built to keep pace with every adventure. It features a round case crafted in silver-toned stainless steel and equipped with the Double Security system for enhanced durability, finished with a brushed treatment for a polished look. Its diameter measures 44.60 mm, with a thickness of 16.20 mm and a weight of 240 g - dimensions that make it a natural fit for men's wrists. The notched bezel with a blue insert features a scale marked from 0 to 60 minutes and a luminescent marker at 12 o'clock. It frames the domed crystal over the dial. Time functions are set via the screw-down crown at 3 o'clock and the two pushers flanking it, with a notched profile for easy grip. Finally, the case back ensures water resistance of 30 ATM.
This model's dial blends modernity and refinement. Its striking blue color brings a fresh, glamorous touch to the wrist. The indicators are white with silver-toned outlines for a bold contrast - including the short arrow-shaped hour hand, the sword-shaped minute hand, and the chronograph seconds hand. They sweep over circular indices topped by an inverted triangle at 12 o'clock. All markers are coated in a luminescent layer for nighttime legibility. The counters at 3 and 9 o'clock track 30 minutes and small seconds respectively. The minute track on the outer edge adds precision, while the date window at 6 o'clock displays the day of the month. The brand's name is signed at 12 o'clock.
Powering this stunning timepiece is a Swiss-made automatic movement - the Valjoux A05.231 bi-compax caliber built on an ETA 7753 base. This 29-jewel movement measures 30 mm in diameter and 7.94 mm in height. It beats at a frequency of 28,600 vibrations per hour and offers a power reserve of 68 hours. A reliable workhorse, it drives the hands, counters, and date display with precision. It features a ball-bearing rotor and an antimagnetic Nivachron hairspring.
This beautiful watch comes fitted with a stainless steel bracelet that enhances its charm and adds an urban edge. It rests elegantly on the wrist and pairs with any outfit. Measuring 21 mm wide, it features 3 rows of brushed and polished links with a lug width of 20 mm. The clasp is a deployment buckle for a secure, comfortable fit.
With water resistance of 30 atmospheres - equivalent to 300 meters - our watch specialists simply have one thing left to say: enjoy the dive. Fully waterproof, this model is ready for anything: showers, baths, swimming, freediving, or scuba diving. That said, to preserve the timepiece's lasting water resistance, our watchmakers recommend avoiding operating the pushers or crown while submerged.
