Strap for DS First Ceramic White

The lug width of the Certina DS First C0144101601100 is exactly 22 millimetres. This measurement is critical for purchasing compatible aftermarket straps. Always verify the width using precision tools, as even a 1-2mm discrepancy will prevent the strap from fitting properly into the watch's lugs.

We recommend a strap crafted from vegetable-tanned leather, preferably in cognac or dark brown. Traditional Florentine vegetable tanning develops a natural patina over time, enhancing the watch's industrial aesthetic. Alternatively, a technical NATO in nylon or vulcanised rubber intensifies its tool watch character, ideal for active pursuits and outdoor environments.

Changing the strap is straightforward. Position the watch on a stable surface with the lugs facing upward. Using a spring bar tool, gently compress the internal spring of the fastening bar. Remove the old strap and insert the new one, ensuring both sides of the bars are securely fixed in their respective lugs. Avoid forcing: the motion should be fluid and controlled.

Yes, any 22mm strap is compatible with the Certina DS First C0144101601100, provided the cross-section does not significantly exceed the original thickness. Artisanal Tuscan straps maintain standardised dimensions and are tested across thousands of models with 22mm lugs. Always verify manufacturer documentation and contact the seller if uncertain.

A high-quality leather strap, made with traditional vegetable tanning, typically lasts 3-5 years of daily wear. Longevity depends on UV exposure, humidity, and cleaning frequency. Straps subjected to constant mechanical stress (such as repeated water immersion) show signs of ageing faster. The patina that forms is a treasured characteristic among collectors, evidence of authentic use. Vulcanised rubber straps last longer, up to 8-10 years.
