Strap for PR 100 Quartz 39 Stainless Steel / Yellow Gold PVD / Silver / Strap

The Tissot PR 100 ref. T101.410.26.031.00 features a 20mm lug width, meaning the distance between the attachment pins on the case is 20 millimetres. This is the standard measurement for Tissot's sport-elegant segment and ensures compatibility with hundreds of certified aftermarket straps.

For a bi-colour stainless steel and gold case like this model, we recommend a dark brown or black alligator strap, which creates chromatic contrast and enhances the gold elements. Alternatively, vegetable-tanned calf leather develops patina over time, adding character; a grey or black NATO fabric maintains the original sporting aesthetic. Your choice depends on daily use: formal for alligator, dynamic for NATO, versatile for calf leather.

Position the watch on a soft surface, supporting the case. Locate the spring bar pins underneath the lugs (small metallic protrusions). Using a spring bar tool, push inward to release the pin and detach the strap; repeat on the other side. Once the original strap is removed, align the new strap's holes with the lugs and press until the pins click into place. Verify that the strap sits securely and does not rotate.

Yes, absolutely. The 20mm lug width is compatible with countless quality straps: vegetable-tanned leather, alligator, shell cordovan, rubber, and NATO fabric. Ensure the strap is designed for 20mm lugs and that the attachment holes match the case dimensions. Specialist brands such as milanostraps.it offer premium 20mm straps with refined finishes (steel buckles, deployant clasps) that integrate seamlessly with the Tissot PR 100.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years with daily wear, provided it is kept dry and protected from excessive moisture and prolonged direct sunlight. Vegetable-tanned leather ages elegantly, developing natural patina. To extend durability, avoid wearing the watch while swimming or showering; clean periodically with a soft, slightly damp cloth. NATO fabric or rubber straps have superior longevity (5–10 years), being more resistant to mechanical wear.
