Strap for DS 4 Two Tone

The Certina DS-4 C0224102203000 features a lug width of 20 millimetres. This dimension is standard for the model and allows the installation of any artisanal strap of the same size. To verify compatibility, measure the space between the two lugs: the value should be precisely 20mm.

The choice depends on usage and dial colour. For formal elegance we recommend alligator with natural patina or vegetable-tanned calf; for daily sportwear, a silk NATO or quality elastomer. All 20mm straps are compatible with your watch and available in our catalogue.

The procedure is straightforward: use a spring bar tool to depress the small pins at the strap ends. Remove the old strap and insert the new one, ensuring the pins engage properly in the grooves. The operation takes approximately 60 seconds. If preferred, strap changes can be performed at Casati Milano atelier.

Yes, entirely. Any artisanal strap with 20mm lug width fits correctly on your Certina DS-4 C0224102203000. Our catalogue offers options in alligator, calf, shell cordovan, NATO and elastomer, selected for construction quality and longevity.

A quality leather strap, with regular care, lasts 3–5 years of daily wear before requiring replacement. Vegetable-tanned leather is particularly durable. To preserve the material, avoid prolonged humidity and occasionally apply specific balms. Elastomer has similar lifespan but greater resistance to humid environments.
