Strap for DS-1

The lug width of the Certina DS-1 C0064072203100 is 20mm. This measurement is taken perpendicularly between the inner edges of the two lug attachments on the case. When purchasing a strap, always verify that the seller specifies 20mm as the lug width to ensure perfect compatibility.

For the C0064072203100, we recommend vegetable-tanned leather straps for an elegant aesthetic, or shell cordovan for those who appreciate natural ageing and patina development. If you engage in water sports, a NATO strap in technical fabric or a synthetic rubber option offers superior durability. Your choice should reflect your intended use case and personal preference. All our 20mm straps are compatible with this reference.

The C0064072203100 features fixed lugs. To replace the strap, use a spring bar removal tool. Position the small lever beneath the spring bar, gently press downward to compress the internal spring, then slide the bar out of its seats. Repeat on the opposite side. Insert your new 20mm strap by seating the spring bar into both lugs until you feel an audible click.

Yes, completely. All straps in the Milano Straps 20mm collection are tested for compatibility with watches featuring 20mm lug widths, including the Certina DS-1 C0064072203100. Always confirm that your chosen strap specifies 20mm lug width for guaranteed perfect fit.

A naturally vegetable-tanned leather strap typically lasts 3–5 years with daily wear, depending on humidity, sun exposure, and cleaning frequency. Shell cordovan, being superior in quality, can last 7–10 years. The ageing and patina that develop over time are appreciated characteristics among collectors, not defects. We recommend rotating multiple straps to distribute wear and extend longevity.
