Strap for PR 100 Chronograph Quartz 41 Stainless Steel / Silver / Bracelet

The lug width of the Tissot PR 100 T101.417.11.031.00 is 20 millimetres. This measurement refers to the distance between the two spring bars that attach the strap to the case lugs. It is a non-standard dimension in the commercial market, requiring careful attention to manufacturer specifications when selecting compatible straps.

The choice depends on intended use and personal aesthetic preferences. For formal contexts, an authentic alligator leather strap or vegetable-tanned calf leather in brown or black represents the pinnacle of refinement. For versatile daily wear, smooth calf leather offers durability and natural patina development. For humid environments or sporting activities, nylon ripstop NATO straps guarantee superior robustness and hygiene. Coloured rubber is ideal for those seeking modernity while maintaining formal elegance.

The strap is secured by two spring bars that pass through the case lugs. Using a dedicated tool (spring bar tool) or a small flathead screwdriver, apply controlled pressure to one spring bar to release the internal spring, then remove the old strap. Insert the new strap, aligning the holes with the lugs, then release the spring bar into its seat. Repeat for the second bar. The operation requires care to avoid scratching the case.

Any strap with a 20-millimetre lug width is mechanically compatible with the Tissot PR 100 T101.417.11.031.00. MilanoStraps offers a curated selection of artisanal straps in natural leather, alligator, shell cordovan, NATO fabrics and rubber in this dimension. Mechanical compatibility is guaranteed; aesthetic choice depends on usage context and desired wrist presence.

Longevity depends on material, tanning quality and daily use patterns. A well-maintained vegetable-tanned calf leather strap typically lasts 3–5 years with regular wear. Alligator leather, more resistant to tearing, can reach 5–7 years. Factors accelerating wear include: body perspiration, humidity, prolonged sun exposure, and repeated flexing at the lugs. Periodic maintenance with specialist conditioning creams significantly extends longevity.
