From Certina, presenting the DS Action (ref. C048.210.44.131.00), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: measuring 34.5 mm in diameter, with a thickness of 10.3 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel. The caseback is closed, and the crystal is sapphire, delivering water resistance to 30000 meters. At a glance, the dial balances texture and clarity: a blue tone with gloss finish, executed in mother of pearl, framed by stick / dot hour markers, and arrow hands. At its heart beats a proven engine: the F05.412 caliber. Introduced in 2025. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
