The Certina DS-2 Turning Bezel is a family of automatic watches with documented steel and titanium configurations. Certina lists the cited models with the same 41.1 mm width, 11.7 mm height, 20 mm lug span, Powermatic 80.611 movement, up to 80 hours of power reserve and 200 m water resistance. The main choice is material and configuration—not a different movement or case size. The available information here comes from Certina’s product and collection pages, not firsthand wear or independent performance testing.
What is the Certina DS-2 Turning Bezel?
It is Certina’s revival of the DS-2, a watch line the brand associates with its history of resistance. Certina’s collection page states, “In 1968, the DS-2 established new benchmarks for resistance.” That is the manufacturer’s heritage framing, not an independently verified comparison with other watches.
A Certina news-index entry dated 28 January 2026 is titled “DS-2: Rooted in heritage, beating in sync,” but its visible description is a Valentine’s Day campaign passage. It does not establish the launch date of the Turning Bezel collection.
How do the documented models compare?
| Reference | Case and bezel | Dial and strap | Listed dimensions and water resistance | Movement |
|---|---|---|---|---|
| C024.607.11.041.02 | 316L stainless-steel case and bezel | Blue dial; Certina lists steel and leather strap or bracelet materials and a quick-release system | 41.1 mm wide, 42.0 mm long, 11.7 mm high; 20 mm lug span; 200 m | Automatic Powermatic 80.611; up to 80 hours; Nivachron balance spring |
| C024.607.11.081.02 | Stainless-steel version | Grey dial; stainless steel and synthetic strap materials; quick-release system. Certina says the strap uses #tide ocean material®, produced from ocean-bound plastic. | 20 mm lug span; Certina lists 200 m water resistance for this cited reference | Automatic Powermatic 80.611; up to 80 hours; Nivachron balance spring |
| C024.607.48.051.10 | Titanium case and buckle; titanium/aluminium bezel | Black dial; synthetic strap | 41.1 mm wide, 42.0 mm long, 11.7 mm high; 20 mm lug span; 200 m | Automatic Powermatic 80.611; up to 80 hours; Nivachron balance spring |
These are manufacturer-listed specifications, not independent measurements. Dimensions and movement details for the blue steel and black titanium references come from Certina’s product pages; the grey model’s cited page establishes its movement and 20 mm lug span, but the comparison does not add dimensions absent from that listing.

Steel or titanium: what changes?
Steel: blue and grey configurations
The blue reference, C024.607.11.041.02, pairs a 316L stainless-steel case and bezel with a blue dial. Certina lists a sapphire crystal with one-sided anti-reflective treatment, 200 m water resistance and a two-year warranty. Its page also lists a quick-release system and steel and leather materials for the strap or bracelet options.
The grey reference, C024.607.11.081.02, is another steel configuration. Its synthetic strap is described by Certina as using #tide ocean material®, which the brand and named material partner describe as made from ocean-bound plastic. That description does not establish broader lifecycle or environmental impacts.

Titanium: black configuration
The black-dial C024.607.48.051.10 uses a titanium case and buckle with a titanium/aluminium bezel and synthetic strap. Certina lists sapphire crystal with one-sided anti-reflective treatment and the same core movement and dimensions as the blue steel reference. The listed materials make it the clearly differentiated option in this group; the specifications alone do not quantify a weight difference or establish how either material feels on the wrist.
What the shared specifications mean—and do not mean
Movement and reserve
Certina specifies the automatic Powermatic 80.611 with a Nivachron balance spring in the cited examples. The stated reserve is up to 80 hours. “Up to” is the manufacturer’s maximum specification, not an independently measured result or a guarantee of identical performance in every circumstance.

Water resistance
Certina lists 200 m, also expressed as 20 bar, for the cited references. This is a manufacturer water-resistance rating; it does not by itself establish ISO 6425 dive-watch certification or recommend a particular diving activity.
Fit and strap changes
The cited blue steel and black titanium models share listed dimensions of 41.1 mm wide, 42.0 mm long and 11.7 mm high, with a 20 mm lug span. The grey reference’s cited specifications confirm a 20 mm lug span. A listed quick-release system can simplify changing a strap on the references whose pages specify it, but 20 mm width alone does not confirm compatibility with every aftermarket strap or attachment.

Which reference makes sense for you?
- Choose the blue steel C024.607.11.041.02 if you want the documented 316L steel case and bezel, blue dial, quick-release listing and steel or leather options.
- Consider the grey steel C024.607.11.081.02 if the grey dial and synthetic strap configuration are the draw, including Certina’s stated #tide material description.
- Consider the black titanium C024.607.48.051.10 if titanium hardware and a black dial are your priorities; its listed movement and dimensions match the blue steel example.
Certina’s indexed collection page showed 18 watches in a page snapshot crawled about five months before 3 October 2026. That count is a dated snapshot, not a dependable current total; confirm the live collection for available references and configurations.
