Strap for Tradition Chronograph Bicolor / Silver

The lug width of the Tissot Tradition T063.617.22.037.00 is 20 mm. This dimension is measured from the centreline of one spring bar to the other, positioning a caliper between the case's lateral lugs. It is essential for selecting compatible straps without risk of abnormal tension on the lugs during wear.

For the steel and rose gold bi-colour, a dark brown or black alligator strap consolidates elegance without chromatic conflict. Shell cordovan, with its natural lustre and evolving patina over time, offers a premium alternative that improves visibly over the years. A stone grey NATO provides contemporary versatility, emphasizing the watch's sophistication.

To change the strap, position the watch with the lugs facing toward you. Use a spring bar tool to gently push the small cylindrical pin inward, releasing the internal spring that retains the strap. Remove the old strap, insert the new one by aligning the holes to the lugs, then use the same tool to reinsert the pin until the safety click engages.

Any strap with a 20 mm lug width is compatible with the T063.617.22.037.00, including those in alligator, vegetable-tanned calf, shell cordovan, cotton NATO, and structured rubber. Compatibility depends exclusively on lug width, not brand. Always verify the technical specifications of the strap before purchase.

The lifespan of a leather strap ranges from 2 to 5 years, depending on the material, frequency of use, and exposure to moisture and light. Alligator and shell cordovan, owing to their fibrous density, tend to last longer than calf leather. Vegetable tanning develops a protective patina that can extend useful life. Proper maintenance—drying the strap after moisture exposure and applying specific balms—significantly extends longevity.
