Strap for Supersport Chrono Yellow Gold / Black / Bracelet

The lug width of the Tissot Supersport T125.617.33.051.01 is 22mm. This measurement indicates the distance between the case lugs where the strap is seated. To verify compatibility, measure with a digital calliper the perpendicular distance between the two upper lugs, keeping the instrument parallel to the watch face. Tolerance margin is ±0.5mm.

The best choice depends on usage and aesthetic preferences. For daily elegance, we recommend calf leather in traditional Tuscan vegetable tanning: the natural patina that develops over time creates unique personalisation. For aquatic activities or humid environments, butyl rubber or TNT maintains elastic properties intact. For maximum versatility, a reversible NATO strap offers two colour configurations with a single purchase, allowing rapid changes via external deployante.

The change is straightforward with the correct tools. Position the watch face-down on a soft mat. Using a spring bar tool (small bifurcated implement), gently press one of the lateral pins towards the case centre: the inner pin retracts, freeing space to extract the old strap. Repeat on the other side. To install the new strap, align the holes at the ends, insert the pins and verify that they lock completely on both sides.

All straps with 22mm lug width are compatible. Milano Straps offers a curated selection: Tuscan calf in vegetable tanning, alligator, vegetable calf, shell cordovan, NATO straps in technical canvas and rubber. Each strap is designed to seat perfectly in the standard case lugs, guaranteeing absence of mechanical play and controlled spring bar wear.

Durability depends on usage and tanning quality. A calf or alligator strap in traditional Tuscan vegetable tanning lasts an average of 3-5 years with daily use, developing precious patina over time. Longevity extends if the strap is exposed to moderate sweat and humidity, as vegetable tanning contains natural tannins that strengthen the fibrous structure. With proper maintenance (regular cleaning, sun exposure for hygienisation), durability reaches 7-8 years.
