Strap for PR 100 Quartz 40 Stainless Steel / Black / Bracelet

The lug width of the Tissot PR 100 T150.410.11.051.00 is precisely 20mm. This dimension is the standard for contemporary sports watches in the 38–42mm range, ensuring broad compatibility with the quality aftermarket strap market. To verify the measurement, position a digital calliper between the inner lug terminals, excluding the outer shoulders.

The PR 100 pairs excellently with high-quality vegetable-tanned leather (French Barenia, aged English calf), which emphasises the case's minimalist character. For everyday versatility we recommend dark brown or black in vegetable-tanned calf with natural tanning. NATO straps in navy or forest green add authentic sports credentials, whilst FKM rubber excels for intensive outdoor use. A satinless steel deployant completes the aesthetic coherently.

Strap replacement is straightforward: use a spring bar tool to remove the elastic pins from the case lugs. Extract the original strap, insert the new strap over the internal spring bar, then re-seat the elastic pin into the lug holes until an audible click confirms security. Repeat on the second lug. Professional assistance is unnecessary for this routine maintenance task.

All straps with a 20mm lug width are compatible with the T150.410.11.051.00, provided the lug terminals are correctly dimensioned to accommodate the original elastic pins securely. We discourage adapters or improvised solutions: opt for straps expressly constructed for 20mm lugs in vegetable leather, military NATO, FKM rubber, or alligator. The straight terminals of the PR 100 require straps with corresponding straight lugs, not tapered.

A quality vegetable-tanned leather strap expressly constructed for 20mm lug width retains excellent durability characteristics for 3–5 years of daily wear, depending on frequency of changes, solar exposure and humidity. Vegetable tanning develops natural patina (positive ageing) that increases aesthetic appeal over time. Replacement is preventive maintenance rather than repair: the original Tissot strap has a comparable lifespan. Shield the leather from prolonged rain and stagnant moisture to maximise longevity.
