The Certina DS Action | family history
Certina's DS Action positions as the value leader in the serious Swiss dive watch category. It carries 300m water resistance meeting ISO 6425, a ceramic unidirectional bezel, and the Powermatic 80 with silicon hairspring and 80-hour power reserve. The watch sells for under $500 new. No other Swiss manufacture with in-house movement credibility and ceramic bezel comes close to this price. The Seiko SKX successor crowd should price this before deciding.
Certina's rugged outdoor and dive family built on the Double Security platform. The DS Action Diver 300m applies the Powermatic 80 inside a properly dive-rated 43mm case with unidirectional rotating bezel.
2016 · DS Action launch as technical value diver
Certina introduced the DS Action line as the sport extension of the DS platform. The Diver spec hit 300m and ceramic bezel from launch, and the Powermatic 80 caliber adoption matched the DS-1's movement specification with a sport-purpose case. The combination was unusual at the price: most watches under $500 offer 200m water resistance and no ceramic bezel.
2020 · Refinement and SKX comparison era
As Seiko discontinued the SKX007 and the replacement SPB series moved upmarket, the DS Action Diver became the natural recommendation for buyers seeking a serious dive tool under $500. The DS Action's Swiss manufacture credentials, silicon hairspring, and 80-hour reserve gave it a technical edge over the Seiko alternatives at the same price. The watch has not required significant revision because the specification was already competitive.
How to read this family
What to consider before buying the DS Action Diver.
- DS Action vs. Seiko SPB: the value diver comparison The Seiko SPB series uses Seiko's in-house 6R35 movement with 70-hour reserve, which is excellent at the price. The DS Action uses the Powermatic 80 with silicon hairspring, which provides antimagnetic performance the Seiko cannot match. Both are ISO 6425 compliant dive watches. The Seiko has stronger collector community and secondary market. The DS Action has superior movement specification on paper. Choose based on whether Japanese tool-watch heritage or Swiss movement specification matters more.
- Is 300m water resistance overkill for recreational diving? For recreational diving to 40m, 100m water resistance is technically sufficient. But a 300m-rated case provides a better pressure-testing certification standard, a more robust crown and caseback seal system, and a longer effective service life before water resistance degrades. It also means you do not need to think about whether the watch can handle the activity. Over-engineering is a feature in dive watches.
- Ceramic bezel or steel bezel: does it matter? Ceramic bezels do not scratch under normal circumstances. Steel bezels develop cosmetic wear marks over years of use. For a tool watch you plan to use actively, ceramic is the correct choice. The DS Action's ceramic bezel is a significant upgrade over steel-bezel alternatives at the same price point. It is not a luxury feature here, it is a functional durability upgrade.

Which ref to buy
The DS Action Diver is Certina's serious sport proposition: 300m water resistance, powermatic 80 movement with 80-hour power reserve, at a price that makes it the most cost-efficient Swiss automatic diver available from a brand with genuine watchmaking history.
- 1Open
DS Action Diver 300m: 300m WR, ETA Powermatic 80 with 80h power reserve, under $700 new.
- The case for it:
- No other Swiss automatic diver at this price point offers the combination of ETA movement, 300m rating, and Certina's Double Security case construction. The powermatic 80 escapement makes this effectively a set-it-and-forget-it watch for daily wear.
- Consider instead if:
- At slightly higher price points, the Oris Divers 65 and Tudor Pelagos carry significantly more collector credibility and secondary market value. The Certina is the value argument, not the aspirational one.
