Strap for DS-1

The lug width of the Certina DS-1 C0064071105100 is 18mm. This dimension represents the distance between the two lugs where the strap is attached to the case. Measurement is performed using a digital calliper positioned on the inner surface of the lugs, ensuring precise compatibility with certified aftermarket straps designed for this specification.

The ideal strap depends on your intended use: for formal contexts we recommend alligator with vegetable tanning or aged calf leather; for daily wear and water activities, fluoroelastomeric rubber (FKM) offers superior resistance; for chromatic versatility, a cotton/polyester NATO strap provides accessible personalisation. All Milano Straps 18mm options are tested for structural and aesthetic compatibility with the DS-1.

Strap replacement requires a dedicated tool (spring bar tool). Position the watch on a soft surface, gently insert the tool into the gap between case and strap, push toward the case centre to compress the spring lug, then remove the pin. Repeat on the other side and insert the new strap, aligning the lug to the attachment points. We recommend professional intervention at our Casati Milano atelier to ensure precision and case protection.

Yes, all certified 18mm straps are compatible with the Certina DS-1 C0064071105100. Milano Straps offers only straps that respect the construction tolerances of this lug width. Before purchasing online, we recommend verifying that the strap specifies 18mm width to guarantee smooth coupling without structural play.

The average lifespan of a leather strap is 3-7 years with daily wear, varying according to frequency of water exposure and tanning method. Milano Straps vegetable-tanned leather straps develop natural patina, increasing aesthetic character over time. We recommend regular cleaning and periodic conditioning with natural waxes to extend longevity and preserve material softness.
