Strap for T-10 Stainless Steel / Silver

The lug width of the T073.310.11.017.01 is exactly 20 mm. This measurement is taken by positioning a digital calliper between the two lateral pins of the case, completely excluding the thickness of the lugs themselves. It is crucial to verify this dimension before purchasing an aftermarket strap, as even a 1 mm deviation would result in incompatibility with Tissot's proprietary lugs.

The choice depends on usage context and aesthetic preferences. For a formal look, we recommend shell cordovan with fine grain, which develops an organic patina over time. For daily versatility, vegetable-tanned calf leather is ideal, as it ages by developing a dark, stratified patina. For those seeking a sport-casual option, a natural twill NATO strap maintains the T-Trend's proportions without adding visual weight to the wrist.

Strap replacement requires a specialised tool: a stainless-steel spring bar tool. Position the tool under the first lateral pin, apply gentle and consistent pressure until the pin slides out completely. Repeat on the opposite side. Then align the new strap's lugs with the empty holes, insert the pin, and press until you hear the locking click. Atelier Casati Milano provides this replacement service with millimetre-precision and personalised technical consultation.

Any 20 mm aftermarket strap is theoretically compatible with the T073.310.11.017.01, since the lugs are proprietary to Tissot and accept standard pins. However, for optimal compatibility, we advise against straps thicker than 4 mm without internal reinforcement, as they could exert abnormal pressure on the lugs during daily wear. Artisanal-quality straps (full-grain leather or shell cordovan) with stainless-steel deployante clasp guarantee longevity and stability.

Lifespan depends on the tanning method, frequency of use, and maintenance. A shell cordovan strap lasts 4–6 years with daily wear and without aggressive chemical treatments. Vegetable-tanned calf leather has similar longevity but ages more visually rapidly (2–3 years for a pronounced patina). NATO straps in natural fibres last 3–4 years before showing signs of fibre wear. Longevity can be extended through periodic conditioning with silicone-free natural creams.
