Strap for DS-1

The lug width of the Certina DS-1 C0064074404100 is 20mm. This measurement represents the distance between the inner shoulders of the lug bar, the space where the strap slides through. Always verify this parameter before purchasing an aftermarket strap to guarantee a perfect fit without lateral play.

For the C0064074404100 in titanium we recommend straps in alligator with vegetable tanning, top-quality calf leather, or NATO solutions in canvas. Alligator emphasises the contrast between natural ageing material and neutral titanium; calf guarantees softness and visible patina development; NATO offers sporting versatility. The choice depends on intended use and your model's dial.

The change occurs by detaching the spring bars that connect the lug to the case. Using a specific tool or small flathead screwdriver, gently compress the spring pin from one side, sliding it towards the lug. The strap detaches easily. Installation of the new strap follows the reverse path, ensuring the pins click firmly into place.

Yes, the C0064074404100 accepts any strap with a 20mm lug width and standard spring bar system. At Milano Straps you will find a dedicated collection of leather, NATO and rubber straps all compatible with this lug size, available in various finishes and colour options.

The lifespan of a leather strap depends on the material (alligator typically lasts 5-7 years, calf 3-5 years) and usage. Humid environments shorten service life, as does prolonged direct sunlight exposure. A well-maintained strap, cleaned regularly and stored away from moisture, guarantees optimal performance for years. The deployant clasp or closure system is equally important to overall durability.
