The Supersport T125.617.17.051.03A, seen from the bench

The Tissot Supersport T125.617.17.051.03A is a contemporary sports chronograph with a 45.50mm stainless steel and aeronautical aluminium case. It features the ETA G10.212 AB calibre with split-seconds chronograph, date indicator, and subdial seconds. The 22mm lug width accommodates robust straps without visual discord. Water resistance reaches 100 metres, suitable for swimming and snorkelling but not apnea diving. This tool watch combines Swiss precision with engineering solutions that reduce weight while maintaining structural rigidity.

Frequently asked questions

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

The lug width is 22mm. This dimension is specific to Supersport chronographs and should be measured perpendicularly between the inner walls of the lugs using a digital calliper to ensure perfect compatibility with replacement straps.

Which strap do you recommend for this Tissot Supersport?

We recommend Tuscan leather with vegetable tanning in dark brown, which complements the technical character of the aluminium and stainless steel case. Alternatively, alligator for formal settings, NATO for intense sports use, rubber for humid environments, or shell cordovan for a vintage aesthetic.

How do I change the strap on a Tissot Supersport?

Use a spring bar removal tool to extract the springs holding the strap to the lugs. Position the tool on the spring, apply gentle downward pressure, then extract the pin. Insert the new strap with the same lug width (22mm) and reinsert the springs until they click into place.

Can I use an aftermarket strap on this model?

Yes, provided the lug width is exactly 22mm and the strap is compatible with the case diameter (45.50mm). Milano Straps offers handcrafted straps specifically sized for this width, ensuring mechanical coupling without excessive play.

How long does a leather strap last on a chronograph like this?

A Tuscan vegetable-tanned leather strap typically lasts 3–5 years with daily wear, depending on perspiration, sun exposure, and maintenance. Regularly applying regenerating balm extends the material's lifespan. Shell cordovan is more delicate in humid environments (18–24 months); alligator, if not frequently wetted, exceeds 7 years.
