Strap for DS-1 Day-Date

The lug width of the Certina DS-1 is 18 mm. This measurement represents the distance between the two attachment pins on the watch case. It is essential to verify this dimension before purchasing an aftermarket strap to ensure a perfect fit.

The Certina DS-1 accommodates multiple strap choices: an alligator or vegetable-tanned calf leather strap for formal occasions, a nylon NATO for robust daily wear, or vulcanised rubber for sporting contexts. Your selection depends on your lifestyle and colour preferences.

To change the strap, use a spring bar tool to extract the attachment pins from the lugs. Position the tool under the pin, apply gentle upward pressure and the pin will compress, allowing removal. Repeat on the opposite side, then insert the new strap by reversing the procedure.

Yes, any 18 mm strap is compatible with your timepiece. Milano Straps offers an extensive selection of artisanal straps in this size, crafted from premium materials including alligator, shell cordovan, vegetable-tanned calf, and NATO. You can personalise your selection online.

The longevity of a leather strap depends on the quality of the tanning and intensity of use. A vegetable-tanned leather strap, properly maintained, can last 5-10 years, developing a fascinating patina over time. Daily wear, perspiration, and sun exposure accelerate deterioration. To extend durability, we recommend periodic cleaning and conditioning with natural waxes.
