Frequently asked questions

What is the lug width of the Certina Heritage Collection C024.462.18.041.00?

The lug width of the Certina C024.462.18.041.00 is 20 millimetres. This measurement is the distance between the lugs (the metal pins on which the strap rests) across the case. You can verify this easily by measuring directly on the case with a digital calliper or ruler. A 20 mm lug width is standard in the contemporary sports chronograph segment and provides access to an extensive catalogue of aftermarket straps.

What is the best strap for the Certina C024.462.18.041.00?

The choice depends on usage and aesthetic preferences. For a formal approach, alligator with vegetable tanning or shell cordovan represent the highest prestige solutions, with natural patina that evolves over time. For daily wear, natural calf in vintage finishes offers elegance without rigidity. For sports and aquatic environments, NATO in high-density nylon or vulcanised rubber ensure durability and simplified maintenance. The 43.36 mm stainless steel case accommodates all these materials without compromise.

How do I change the strap on the Certina Heritage Collection?

Strap replacement is a straightforward procedure. Obtain a spring bar tool (extractor tool for pins), available from any watch retailer. Position the watch face-down on a soft surface, insert the bifid tip of the spring bar tool under the pin, exert gentle downward pressure to release the internal spring, extract the pin. Repeat on the other side. Install the new strap by reversing the procedure. If you prefer not to do it yourself, a professional watchmaker will complete the operation in minutes.

Can I use an aftermarket strap on this Certina?

Yes, absolutely. Any strap with the correct lug width (20 mm) is compatible with the Certina Heritage Collection C024.462.18.041.00. Artisanal straps of superior quality, in noble materials such as alligator, shell cordovan or calf, are particularly recommended for this model because they enhance the case's build quality and overall aesthetic balance. Aftermarket straps also provide seasonal and contextual versatility.

How long does a leather strap last on a watch?

The lifespan of a leather strap depends on the material, the quality of craftsmanship and the intensity of use. A high-quality artisanal alligator or shell cordovan strap typically lasts 3–5 years with regular daily use. Natural calf, particularly if treated with protective waxes, reaches 2–4 years. Longevity increases if you alternate the strap with other solutions (NATO, rubber) or reserve it for specific contexts. Ambient humidity, frequency of water exposure and lack of maintenance can reduce lifespan. A worn strap is easily replaced without significant cost relative to the case, making leather straps the most personal and versatile component of the watch.
