Strap for PR 100 Quartz 39 Stainless Steel / Silver / Strap

The Tissot PR 100 reference T101.410.16.031.00 features a lug width of 20mm. This dimension is fixed and represents the internal distance between the two lateral lugs where the strap attaches to the case. It is essential to verify this measurement before purchasing an aftermarket strap, by placing a ruler between the lugs and reading the internal value.

The PR 100 pairs exceptionally well with genuine alligator leather, vegetable-tanned calf, and NATO straps. Alligator enhances perceived quality through its natural geometric texture. Vegetable-tanned calf develops a natural patina over time. NATO straps offer chromatic versatility and informal character. Technical rubber is ideal for summer use. Untreated raw leather is inadvisable: the 20mm lug width requires calibrated thickness.

Remove the old strap by extracting the lateral spring bars using a dedicated tool or the blunt end of a knife. Insert the new bars into the holes of the new strap's lug area, ensuring perfect alignment. Confirm that the bars click fully into the case seats. Never force the bars: correct insertion should feel fluid. Verify stability by gently pulling before wearing the watch.

Yes, any strap manufactured for 20mm lug width is compatible with the PR 100 T101.410.16.031.00, provided construction quality is certified and thickness calibrated. Artisanal straps with vegetable or alligator finishes guarantee superior structural and aesthetic compatibility. Verify that the supplier explicitly specifies 20mm lug width and that spring bars are included or compatible.

A high-quality leather strap (calf, alligator, shell cordovan) typically lasts 3–5 years with daily wear, depending on the tanning method. Vegetable-tanned leather develops natural patina and becomes softer over time, extending perceived longevity. Exposure to perspiration, humidity, and UV radiation accelerates ageing. Regular maintenance (cleaning with damp cloth, moisture absorption) prolongs lifespan. A well-crafted strap can be regenerated through leather reconditioning.
