Certina DS Action GMT Powermatic 80 41mm Mens Watch

Ref. C0329292605100

The DS (Double Safety) concept has underpinned Certina's engineering philosophy since 1959, and the Action GMT brings it into GMT territory. This reference — launched in 2024 alongside a black-and-green and a Pepsi-bezel sibling — takes the most distinctive path of the three. The gold PVD case, split brown-and-black 24-hour bezel insert, and brown leather strap land far from the sportswear read of the others, and reviewers reached quickly for "Root Beer" as shorthand. It is a reasonable comparison: the combination reads as the dressy, slightly retro variant of what is otherwise a straightforward sport-GMT trio. The movement earns attention independently. The ETA Powermatic 80.661 is a Flyer-style GMT, meaning the local-time hand sets without stopping the seconds — a practical advantage when crossing time zones in use rather than on a watchbench. The 80-hour power reserve is generous enough to survive a long weekend off the wrist, and the Nivachron balance spring provides magnetic resistance without the need for a separate soft-iron cage. Both the crown and caseback are screw-down, so the 200m rating is not a theoretical figure. The one thing the leather strap changes beyond aesthetics is weight distribution. The stainless siblings carry their mass differently; on brown leather, this sits closer to the wrist and loses some of the tool-watch bluntness. The finishing is mostly brushed across the case, with polishing confined to the crown and the outer bezel rim — restrained, and consistent with the vintage-leaning palette the colour choices already suggest.
