Frequently asked questions

What is the lug width of the Tissot Supersport T125.617.17.051.03?

The Tissot Supersport T125.617.17.051.03 features 22mm lug width. This measurement is standard for chronographs with a 45.50mm case diameter and is compatible with all Milano Straps 22mm artisanal straps without structural modifications.

What is the best strap for the Tissot Supersport T125.617.17.051.03?

For the Supersport, we recommend a strap in vegetable-tanned leather or vegetable calf: the sporty profile of the watch benefits from the natural ageing of the material and the textured grain that complements the aluminium and stainless steel case. Tobacco brown is the ideal colour choice, maintaining contrast with the dark dial without visual conflict.

How do you change the strap on a Tissot Supersport T125.617.17.051.03?

The strap is secured by spring bars to the watch lugs. Using a strap removal tool or a rounded-edge knife, press the inner pin to release the spring, then withdraw the old strap. Insert the new strap by sliding the spring bar through the lug until the spring catches again. The operation takes just a few minutes.

Can aftermarket straps be used on a Tissot Supersport T125.617.17.051.03?

Yes, absolutely. Any strap with 22mm lug width is compatible with the T125.617.17.051.03 without adaptations. Milano Straps offers a specialised collection of Italian leather, NATO and technical rubber, all crafted with artisanal excellence to guarantee aesthetic and structural quality.

How long does a leather strap last on a Tissot Supersport T125.617.17.051.03?

The lifespan of a leather strap depends on usage and care. With moderate daily use and regular maintenance (cleaning, protection from excessive moisture), a vegetable-tanned or vegetable calf strap maintains structural integrity for 3 to 5 years. Ageing is part of the material's characteristic, not a defect: the strap evolves chromatically and tactilely, creating unique patina.
