Certina
DS Caimano C0172101105700— lug 15mm

The lug width of the Certina DS Caimano C0172101105700 is 15mm. This precise measurement is determined by the distance between the case lugs and ensures that the strap adheres perfectly without forcing. To verify, measure with a caliper the distance between the two lugs, positioning the tool perpendicularly to the vertical axis of the watch. A 15mm strap guarantees both correct aesthetics and necessary structural support, avoiding unwanted play or instability.

The most appropriate strap material depends on usage and aesthetic preferences. Alligator represents the most sophisticated choice, thanks to its characteristic texture and softness that enhances the compactness of the case. Vegetable-tanned calf leather offers versatility and develops a natural patina over time. A woven NATO strap in neutral tones ensures practicality without visual compromise. Vulcanised rubber is ideal for sports or humid environments. Each material confers a different identity to the model, to be chosen based on your lifestyle and frequency of use.

Changing the strap requires the use of a spring bar removal tool. Position the watch on a stable surface, identify the small holes on the inner side of the lug, insert the compression tool to squeeze the spring pin, then extract the pin from the case. Repeat on the other side. To install the new strap, align the strap holes with the pins, insert the first pin whilst compressing it with the tool, check that it is securely attached, then repeat on the other side. Ensure that the pins are fully inserted before wearing the watch.

Yes, any artisanal 15mm strap is perfectly compatible with the Certina DS Caimano C0172101105700. Compatibility is guaranteed by the lug width, which determines the coupling with the case pins. Milano Straps offers a collection of 15mm straps crafted in various materials—alligator, calf, NATO, rubber—all ready for shipment and customisable according to your colour and finish preferences. Choosing a quality aftermarket strap significantly extends the aesthetic versatility of the model.

The lifespan of a leather strap depends on material quality, frequency of use and environmental conditions. An artisanal alligator or calf leather strap, with daily wear, maintains performance and aesthetic appearance for 3-5 years. Constant exposure to sun, water and humidity reduces this window, as it accelerates material ageing. Vegetable-tanned leather, whilst changing and developing a natural patina, increases in character over time. Keeping the strap dry when possible and occasionally applying a specific leather balm significantly extends its life, transforming it from a disposable accessory into an object that accompanies the history of your watch.
