Strap for Supersport Chrono Stainless Steel / Black

The lug width of the Tissot Supersport T125.617.16.051.00 is 22mm. This measurement is fixed and non-negotiable: the strap must pass through the case lugs without excessive play or forced insertion. It is impossible to fit 20mm or 24mm straps without risking damage to either the watch or the strap.

For a chronograph of 45.50mm diameter like the Supersport, we recommend three primary options: 1) NATO in cotton-polyester (maximum robustness and practicality), 2) black calf leather in vegetable tanning (classical elegance with natural patina development), 3) FKM rubber (modernity and stylistic neutrality). Your choice depends on usage: dynamic sportive contexts favour NATO, refined daily wear favours leather, technical environments favour rubber.

Strap replacement requires: 1) a properly-sized spring bar tool, 2) care to avoid scratching the case. Position the watch on a soft surface, insert the spring bar tool into the lug access hole, push inward to release the spring, remove the old lug, insert the new strap's lug ensuring the spring seats correctly. If inexperienced, contact a local watchmaker to prevent damage.

Yes, any artisanal 22mm strap is compatible with the T125.617.16.051.00, provided the lugs are dimensionally correct. Milano Straps offers artisanal straps in leather, NATO, and rubber specifically tested for this lug width. Always verify the 22mm specification before ordering: whilst this is the standard, construction quality varies significantly between manufacturers.

A quality calf leather strap, subjected to moderate use, lasts 3–5 years before requiring replacement. The mass of the Supersport case (45.50mm in aluminium-stainless steel) accelerates leather wear compared to lighter models. Vegetable-tanned straps age more gracefully aesthetically, developing characteristic patina. NATO and rubber straps have superior longevity (5–7 years) owing to material inherent resistance.
