Strap for PR 100 Quartz Chronograph Tour de France

The lug width of the Tissot PR 100 t150.417.11.051.00 is 20mm. This is the horizontal distance between the two spring bars that anchor the strap to the case. It is essential to verify this measurement before purchasing an aftermarket strap, as an incorrectly sized strap will not fit properly and may damage the case. To measure the lug width, use a ruler or digital calliper, positioning it perpendicular to the bars and reading the distance from the inner point of one bar to the inner point of the other.

The ideal strap depends on intended use. For formal and professional wear, we recommend alligator or calf leather with vegetable tanning in dark brown or black tones, which accentuate the aesthetic sobriety of the PR 100. For daily versatility, vegetable-tanned calf in natural brown offers elegance and natural patina development over time. For sporty or humid environments, a cotton NATO strap or synthetic rubber ensures durability and water resistance. Shell cordovan represents a premium option for those seeking extraordinary leather quality and longevity.

Changing the strap is a straightforward operation requiring no specialised tools. Position the watch face-down on a soft surface. Locate the two spring bars anchoring the strap to the case (one on each side). Using a thin, flat instrument (or a strap removal tool), apply gentle inward pressure to release the spring bar mechanism. Remove the old strap. Align the new strap with the holes and insert the bars until fully engaged. Verify that the strap is secure before wearing the watch.

Yes, any strap equipped with 20mm lugs is compatible with the Tissot PR 100 t150.417.11.051.00. Artisanal straps from Milano Straps are custom-crafted for this specific lug width and guarantee superior construction quality compared to standard OEM straps. Always verify that the new strap has been produced specifically for the 20mm size, as even 1mm variations can compromise fit and security.

Leather strap longevity depends on material, tanning method, and usage patterns. High-quality artisanal calf leather with vegetable tanning, subjected to daily wear and proper maintenance, can last 3 to 7 years. Alligator, being denser and more resilient leather, can exceed 10 years. Shell cordovan is renowned for lasting over 15 years. Maintenance includes drying after moisture exposure and occasional application of leather-specific balms. Avoid prolonged water immersion, even if the strap is well-treated.
