Strap for PR 100 Chronograph Quartz 41 PVD / Black / Milanese

The lug width of the Tissot PR 100 T101.417.33.051.00 is 20mm. This measurement refers to the distance between the horizontal lugs (or spring bar seats) on the watch case. To verify compatibility, measure the slot where the strap attaches: it must be exactly 20mm. Do not confuse this with the total case width, which is a different dimension. A 20mm lug width allows you to use the full range of artisanal strap materials and thicknesses available on the market.

The choice depends on your intended use. For formal occasions, we recommend black alligator or vegetable-tanned calf leather in cognac tone: these enhance the elegance of the stainless steel case. For sports and casual settings, a navy NATO fabric or vulcanised rubber maintain the instrument-like character of the chronograph. For everyday versatility, a tobacco-brown calf leather offers the right balance between aesthetics and practicality. The 20mm lug width accommodates full-thickness straps, which guarantee superior comfort and extended durability.

To change the strap on the Tissot PR 100 T101.417.33.051.00, remove the watch and place it face-down on a soft surface. Use a spring bar remover tool to compress the elastic pin located beneath each lug. Gently lift the pin from the case seats, working from the lower lug first. Once both pins are removed, the old strap detaches easily. Align the new strap's holes with the pins and reverse the procedure. If you prefer professional assistance, visit a qualified watchmaker to avoid damaging the case.

All artisanal straps with 20mm lug width are compatible with the Tissot PR 100 T101.417.33.051.00. At milanostraps.it, you will find options in alligator, shell cordovan, vegetable-tanned calf leather, cotton NATO, and vulcanised rubber. Ensure that the strap thickness (typically 3-4mm) does not create excessive tension on the spring bars: overly rigid straps may damage the case lug seats. High-quality artisanal straps offer superior aesthetics and comfort compared to factory-standard straps.

Strap longevity depends on material quality, thickness, tanning method, and usage patterns. A high-quality vegetable-tanned calf leather, worn daily, typically lasts 3-5 years before showing significant wear. Alligator, being more robust, can last 5-7 years. The natural patina that develops over time is part of authentic leather's appeal—it is not degradation but aesthetic evolution. To extend lifespan, avoid prolonged water exposure, apply protective balm occasionally, and rotate between straps to reduce daily mechanical stress.
