The blue Certina DS Action Day-Date pairs an automatic day-date display with a 41 mm steel case, sapphire crystal, 20-bar water resistance and a stated power reserve of up to 80 hours. The exact details depend on the reference: Certina lists blue models on different straps, and the synthetic-strap reference C032.430.18.041.01 is marked no longer available on its official page.
Which blue DS Action Day-Date reference is this?
“Blue DS Action Day-Date” does not identify a single configuration. Certina’s official pages cover at least two blue references with different strap setups and listing status. Check the reference number on the product page or watch documentation before treating a specification, strap, price or availability notice as applying to the watch you are considering.
| Reference | What the official listing establishes | Availability or price |
|---|---|---|
| C032.430.18.041.01 | Blue dial; synthetic quick-release strap; 316L stainless-steel buckle. The listed movement is POWERMATIC 80.621. | Certina marks this product “no longer available.” Certina product page. |
| C032.430.16.041.00 | Blue configuration listed in Certina’s Swiss regional store. The official listing does not establish that all specifications or strap details match the other reference. | Listed at CHF 695.00 on Certina’s Swiss regional store when accessed in 2026; this is a regional listing, not a universal price or guarantee of current stock. Certina Swiss listing. |
What makes the design elegant and pragmatic?
The design description comes from the manufacturer, rather than an independent wear assessment. Swatch Group’s 2019 launch announcement describes a dark-blue sunray dial with sand-colored accents and Super-LumiNova-coated hands. Certina identifies the blue luminous material as Super-LumiNova BG W9, which glows blue after absorbing light. Swatch Group’s 2019 announcement and the Certina product page provide those descriptions.
The practical side is more concrete: the watch combines an automatic movement and day-date display with a sapphire crystal, a stated 20-bar water-resistance rating and a long stated power reserve. Those specifications describe capability on paper; they do not substitute for independent testing or a personal fit assessment.

What are the dimensions and water resistance?
For reference C032.430.18.041.01, Certina lists a 41.00 mm case diameter, 11.96 mm case height, 20.00 mm lug spacing and net weight of 100 g. The case and bezel are 316L stainless steel. These figures belong to that reference and should not automatically be applied to another blue variant. Certina’s specifications.
Certina rates the same reference to 20 bar, equivalent to 200 m. This is the manufacturer’s stated water-resistance rating, not evidence here of an independent immersion test. Its crystal is sapphire with anti-reflective treatment on one side.

How long is the Powermatic 80 power reserve?
Certina specifies up to 80 hours for the automatic POWERMATIC 80.621 movement in reference C032.430.18.041.01, which also has a Nivachron balance spring and day-date display. “Up to” is the manufacturer’s stated maximum; it is not a timing-test result. Swatch Group also cited up to 80 hours in its 2019 launch announcement. Certina; Swatch Group.
Is the blue Certina DS Action Day-Date still available?
Availability depends on the reference and region. Certina marks C032.430.18.041.01 as no longer available on its product page, while its Swiss regional store showed C032.430.16.041.00 at CHF 695.00 when accessed in 2026. Neither status should be read as a worldwide stock statement: check the exact reference and your local Certina store or retailer before buying.

What strap fits the Certina DS Action Day-Date?
Certina lists a synthetic quick-release strap and a 316L stainless-steel buckle for C032.430.18.041.01, with 20.00 mm between the lugs. That makes a 20 mm strap a plausible starting point for this reference, but lug width alone does not confirm fit or compatibility with its quick-release hardware. Verify the reference and attachment system before ordering a replacement. Do not assume the same strap configuration for C032.430.16.041.00.

The official specifications and launch description establish the listed materials, dimensions, movement features and design details. They do not establish hands-on comfort, real-world timekeeping, durability, or how the watch wears on a particular wrist. No independent comparative test statistic is available in the cited sources, so those qualities cannot be responsibly presented as tested results.
