FAQ
What is the lug width of the Certina DS First C0142351101101?
The lug width of the Certina DS First C0142351101101 is 18mm. This measurement is essential when ordering a compatible strap: the strap must fit into the watch's lugs with minimal tolerance. Always verify this dimension before purchasing an aftermarket strap, as an incorrect width will not attach properly to your timepiece.
Which strap do you recommend for the Certina DS First?
For the Certina DS First, we recommend three primary options: an alligator strap with vegetable tanning for refined aesthetics; Italian calf leather with natural patina for daily wear and visible ageing over time; a NATO strap in heavyweight fabric to emphasise the sports character of the ceramic case. Your choice should reflect your lifestyle and the watch's dial colour.
How do you change the strap on an 18mm lug width watch?
To change the strap on an 18mm lug width watch, use a spring bar removal tool to compress the elastic pins securing the strap to the case lugs. Position the tool gently in the lower groove of the pin, compress it and slide the old strap downward. Repeat with the new strap, ensuring the pins click correctly into their housings. Avoid forcing: a gentle operation requires less than one minute per lug.
Is an aftermarket strap compatible with the Certina DS First C0142351101101?
Yes, an 18mm aftermarket strap will be compatible with the Certina DS First C0142351101101, provided its spring bars have the correct geometry for the case's integrated lugs. The strap must measure 18mm at the base of the pins. Bespoke artisanal straps offer the finest compatibility and allow customisation in material and finish.
How long does a leather strap last on a watch like the Certina DS First?
The lifespan of a leather strap depends on material quality and usage conditions. A high-quality calf leather or shell cordovan strap lasts 3–5 years with daily wear. An alligator strap with vegetable tanning can exceed 7–10 years. Frequent exposure to moisture, heat and UV rays reduces longevity. Regular maintenance—gentle cleaning, drying and conditioning with natural wax—significantly extends the strap's life.
