Strap for DS-2 Bracelet

The Certina DS-2 reference C0244101105100 is equipped with a 21mm lug width. This precise measurement requires a strap with an external width of 21mm. To verify it, measure the distance between the two lugs holding the original strap; you should obtain 21mm of total lug width. It is a rare and precise dimension that does not tolerate approximations.

For the 40mm Certina DS-2, we recommend an alligator in oil tanning with natural grain, or a quality calf leather in vegetable tanning. Both pairings convey the constructive seriousness that characterises the watch. If you prefer practicality, a NATO in gabardine canvas with a natural leather backing represents an elegant compromise. Your choice depends on your daily style and usage context.

Changing the strap on your Certina DS-2 C0244101105100 requires a specific tool: a spring bar removal tool or lug punch. Position the watch on a soft surface, locate the two horizontal pins that hold the strap, and use the punch to gently compress the spring beneath the pin, sliding it outward. Once the pin is extracted, the strap separates easily. The reverse operation allows you to fit the new strap. If you are uncertain, consult a professional watchmaker.

The Certina DS-2 C0244101105100 is compatible with all straps featuring a 21mm lug width. At MilanoStraps you will find a curated selection of leather straps (alligator, calf, shell cordovan), NATO, and technical rubber, all dimensioned for this specific measurement. Ensure that your chosen strap has an external width of 21mm and thickness appropriate for the case.

The longevity of a leather strap depends on material quality and intensity of use. An alligator or quality calf, with vegetable tanning, worn daily on a 40mm Certina DS-2, maintains integrity and aesthetics for 3–5 years before requiring replacement. Factors such as humidity, sun exposure, and usage type significantly influence durability. Periodic maintenance (cleaning, light conditioning) substantially extends strap life.
