Strap for Visodate Powermatic 80 Stainless Steel / Silver / Bracelet

The Tissot Heritage T118.430.11.271.00 features a 21mm lug width (distance between the pin points). This is the standard specification for 42mm Heritage cases. Measurement is taken externally between the two pins installed in the case back. All standard 21mm straps are mechanically compatible with this reference.

For the T118.430.11.271.00, we recommend alligator straps (cognac or black brown) for formal elegance, vegetable-tanned calf for comfort and natural patina development, or NATO nylon for sporting versatility. If your model features a blue dial, light cognac alligator creates ideal contrast. Choice depends on intended use and personal aesthetic preference.

Position the watch with the case back facing upward. Using a spring bar tool, gently compress the small spring within each lug pin housing. Extract the old pin by pulling laterally. Align the new strap, insert the pin, and release the spring mechanism. Verify full seating of the pin. Consult a qualified watchmaker if you lack experience with this procedure.

Yes. Any strap featuring standard 21mm pins is mechanically compatible. MilanoStraps provides an extensive range of artisanal straps in leather, alligator, calf, NATO, and rubber—all tested for the T118.430.11.271.00. The Casati Milano atelier offers aesthetic consultation by appointment to identify the most appropriate solution.

A vegetable-tanned calf strap typically lasts 2–4 years under moderate daily wear. An alligator strap, being more durable, lasts 4–6 years. Longevity depends on frequency of use, humidity exposure, and maintenance practices. Regular cleaning with a soft cloth and storage in dry conditions significantly extends leather lifespan.
