Frequently asked questions

What is the exact lug width of the Tissot Touch T013.420.17.011.00?

The lug width of the Tissot Touch T013.420.17.011.00 is 21 mm (21.10 mm precisely). This dimension is specific to this model and requires straps manufactured to strict engineering tolerances. It is not compatible with standard 20 mm or 22 mm aftermarket straps.

Which strap material is most recommended for the Tissot Touch T013.420.17.011.00?

For the Tissot Touch T013.420.17.011.00, we recommend alligator or vegetable-tanned leather straps, which enhance the contemporary aesthetics of the brushed steel square case. Alligator offers formal finishing and geometric rigour; vegetable-tanned leather with natural patina dialogues authentically with the steel's aging process. For sport contexts, NATO or FKM rubber maintains the functional profile of the design.

How do you change the strap on a Tissot Touch T013.420.17.011.00?

The strap is removed by acting on the lugs of the case using a proper spring bar tool. Gently push inward the spring-tension mechanism that retains the pin, then extract the pin from the lugs. The new 21 mm strap is installed by reversing the procedure. We recommend consulting a specialist to avoid scratching the case.

Is the Tissot Touch T013.420.17.011.00 compatible with quality aftermarket straps?

Yes, the Tissot Touch T013.420.17.011.00 is fully compatible with quality artisanal aftermarket straps, provided the lug width is exactly 21 mm. Straps crafted by specialised artisans such as Casati Milano guarantee tight-tolerance construction, reinforced stitching and premium materials, significantly improving aesthetic and tactile performance compared to OEM factory straps.

What is the average lifespan of a leather strap for the Tissot Touch T013.420.17.011.00?

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3-5 years with moderate daily wear, depending on exposure to perspiration, humidity and UV radiation. Vegetable-tanned leather develops natural aging patina over time. Regular maintenance (gentle cleaning, thorough drying, conditioning with natural beeswax) significantly extends durability and enhances the patina's aesthetic development.
