Frequently asked questions

What is the lug width of the Certina DS First C0144101105100?

The lug width of the Certina DS First C0144101105100 is 22 mm. This measurement determines compatibility with any aftermarket strap; always measure the space between the lugs before ordering a replacement strap.

Which strap is most suitable for the Certina DS First C0144101105100?

It depends on usage. For formal settings, we recommend leather with vegetable tanning (Testa di Moro) or shell cordovan. For sports activities, a grey-black NATO or vulcanised rubber strap. The ceramic case pairs particularly well with dark tones and natural textures.

How do I change the strap on the Certina DS First C0144101105100?

Use a spring bar tool to gently lift the lugs. Insert the tip into the groove of each lug, slide out the old strap, and slide the new one into place, ensuring the terminals sit correctly. Always verify that the strap is positioned symmetrically.

What is the difference between an OEM strap and an aftermarket one for the C0144101105100?

The original Certina strap is optimised for the watch's specific terminals. 22 mm aftermarket straps offer aesthetic versatility and often better value: you can change the look whilst keeping the same case. Quality depends on the manufacturer; vegetable-tanned leather and vulcanised rubber guarantee durability.

How long does a leather strap last on the Certina DS First C0144101105100?

A vegetable-tanned leather strap, with moderate use, lasts 2–4 years before requiring replacement. The patina improves over time, but the material wears naturally. Factors such as climate, humidity, and frequency of use affect longevity. Rubber straps last 3–5 years with regular maintenance.
