Frequently asked questions

What is the lug width of the Certina DS-8 C045.410.26.031.00?

The lug width of the Certina DS-8 C045.410.26.031.00 is 20mm. This measurement is taken from the outer left lug to the outer right lug on the case. It is a classic standard that provides access to a wide variety of artisanal straps, both leather and textile.

What is the best strap for the Certina DS-8?

The best choice depends on use case. For formal wear, we recommend alligator or vegetable-tanned calf leather, which offer elegance and aesthetic evolution over time. For versatile daily wear, calf leather with fine grain maintains presentation despite daily wear signs. For dynamic environments, a cotton-nylon NATO offers durability and practicality. For sports and travel, FKM rubber provides total water resistance.

How do you change the strap on a Certina watch?

Position the watch on a soft surface. Using a thin tool (spring bar tool), push the elastic pin laterally and gently lift the lug from the case attachment. Repeat on the other side. Insert the new strap, aligning the holes with the case lugs, then reinsert the elastic pin. Verify correct positioning by checking that the strap does not move.

Is a 20mm aftermarket strap compatible with the C045.410.26.031.00?

Yes, any strap with a 20mm lug width is compatible. Milano Straps artisanal straps are constructed specifically for this measurement and guarantee perfect fit. Always verify that the strap is designed for 20mm watch cases and features standard 1.8mm diameter spring bar holes.

How long does a leather strap last on a watch like the Certina DS-8?

With moderate daily use, a quality artisanal leather strap lasts 3-5 years before requiring replacement. Longevity depends on ambient humidity, frequency of wear, and maintenance care. Vegetable-tanned leather, protected from dirt and excessive moisture, can last even longer. An FKM rubber strap has slightly greater durability, especially in humid climates.
