Strap for Heritage Porto Mechanical Stainless Steel / White

The lug width of the Tissot Heritage T128.505.16.012.00 is 16mm. This measurement represents the internal distance between the two lugs of the case and determines compatibility with aftermarket straps. To verify it correctly, use a digital calliper positioned perpendicularly between the lugs.

For a watch with the dressy vocation of the T128.505.16.012.00, the ideal strap is alligator with vegetable tanning, in medium brown or cognac shades. This material offers elegance, immediate comfort and develops a golden patina over time. Alternatively, matte calf leather ensures aesthetic discretion, whilst vulcanised rubber provides practicality for daily use without compromising quality.

To change the strap, proceed as follows: 1) Position the watch with the caseback facing upwards; 2) Identify the spring bars holding the original strap (usually positioned under the lugs); 3) Use a dedicated tool (spring bar tool) to compress and extract the spring bars; 4) Remove the old strap; 5) Insert the spring bars into the new strap aligning them to the grooves; 6) Position the spring bars in the case lugs until you hear a click. If unfamiliar with the process, consult an expert.

Yes, aftermarket 16mm straps are perfectly compatible with the T128.505.16.012.00. What matters is ensuring the lug width is actually 16mm (not 14mm or 18mm) and that the spring bars suit that width. At Milano Straps you will find straps in various materials (alligator, calf, NATO, rubber) specifically calibrated for this size.

Durability depends on usage intensity and material quality. An alligator or calf strap with vegetable tanning typically lasts 3-5 years of intensive daily use, potentially extending to 7-8 years with rotation to other straps. Deterioration accelerates with prolonged exposure to moisture, sweat and UV rays. Proper maintenance (periodic cleaning, conditioning with natural oils) significantly extends the strap's service life.
