Frequently asked questions

What is the lug width of the Certina Heritage Collection C024.462.36.091.00?

The lug width is 20 mm. This dimension allows for compatibility with a broad selection of artisanal straps without compromising mechanical fit or visual proportions of the case.

Which strap is recommended for the Certina Heritage Collection?

For this Swiss chronograph, we recommend a vegetable-tanned calf leather strap for daily elegance, alligator for formality, or NATO for a sportive approach. Your choice should reflect your use case and dial colour.

How do I change the strap on the Certina Heritage Collection C024.462.36.091.00?

Use a spring bar tool to gently extract the tension springs (spring bars) from the lugs. Align the holes of your new strap with the lugs and reinsert the spring bars, ensuring symmetrical and secure positioning.

Can I use an aftermarket strap on this Certina?

Yes, any strap with a 20 mm lug width is compatible. Ensure the tang thickness falls within standard parameters (typically 2.5–3 mm) and that the strap is not excessively rigid, as this could stress the spring bars.

How long does a leather strap last on a frequently-worn chronograph?

A quality leather strap, vegetable-tanned, typically lasts 3–5 years under moderate daily use. Humidity, perspiration, and UV exposure accelerate wear. Regular maintenance with conditioning creams extends its lifespan.
