Strap for Couturier Automatic Small Second

The lug width (ansa measurement) of the Tissot Couturier T035.428.16.031.00 is 20mm. This measurement is determined by the distance between the two lugs (pins) that connect the strap to the case and remains consistent across all examples of this model. To verify, place the watch face-down and measure the distance between the horizontal lugs on the case.

The optimal strap choice depends on intended usage. For formal contexts, we recommend alligator or vegetable-tanned calf leather, which imparts sartorial sophistication to the Couturier. For daily and sporty use, a robust cotton NATO or natural rubber guarantees practicality without compromising elegance. The colour should harmonise with the dial: with blue dials, a chocolate brown or cognac tone works exceptionally well.

To change the strap, position the watch case-up and use a pin remover tool or a small blunt chisel and hammer. Identify the two pins protruding slightly from the case sides: gently push them upward from inside using the tool, taking care not to scratch the case. Once the pins are extracted, the old strap releases easily. Insert the new strap by aligning its holes with the pins and reverse the procedure.

Any strap with a 20mm lug width is compatible with the Couturier T035.428.16.031.00. This includes leather straps (alligator, calf, shell cordovan), NATO, rubber, and even third-party steel bracelets. Compatibility is determined solely by lug width; always verify that the new strap measures exactly 20mm between the anchor holes.

Leather strap longevity depends on material type and usage patterns. Vegetable-tanned alligator typically lasts 3–5 years with daily wear, thanks to the leather's lower porosity. Italian vegetable-tanned calf has an average lifespan of 2–4 years, as it is more susceptible to moisture absorption and natural patina development. Cotton NATO straps endure 4–6 years without significant degradation. Natural rubber maintains structural integrity for 3–4 years before hardening. Factors including perspiration, sun exposure, and humid climates accelerate ageing.
