Strap for Autavia Isograph Calibre 5 Stainless Steel / Blue / Bracelet

The lug width is 20mm. This dimension is calibrated to proportion correctly with the 42mm case, ensuring a balanced wrist presence with the strap descending gracefully from the lugs without volumetric excess.

It depends on usage. Natural alligator with vegetable tanning enhances sporting elegance while developing patina over time. Calf leather offers chromatic versatility and comfort; natural rubber is ideal for marine activities or humid climates. For authentic aviator aesthetics, a NATO canvas with rubber backing combines period-correct appearance with function.

Position the watch on a soft cushion. Using a spring bar tool, gently press downward to release the internal spring, then extract the pin. Repeat on the opposite side. Insert the new strap by aligning its lugs with the guides and push the pins until they click into position. Do not force: a light click indicates correct seating.

Yes, completely. All our 20mm straps are produced to precise tolerances and assembled on professional equipment. We guarantee full compatibility with TAG Heuer lugs and controlled flexibility for secure fitting.

A quality alligator or calf strap lasts 3–5 years under normal daily wear conditions. Longevity depends on ambient humidity, frequency of use, and care. Vegetable tanning ages by developing patina, not degradation; tears appear only under anomalous tension. Annual inspection and gentle cleaning significantly extend useful life.
