Strap for PR 100 Sport Chic Chronograph 38 Stainless Steel / Silver / Bracelet

The lug width of the Tissot PR 100 T101.917.11.031.00 is 19mm. This is a model-specific standard, now rare in contemporary watchmaking. To verify strap compatibility, measure the distance between the lugs with a digital calliper: it must be exactly 19mm, not 20mm or other variations.

The ideal strap depends on usage: for sportive elegance we recommend alligator leather or vegetable-tanned calf, in dark brown or black. For daily versatility, tino-dyed calf develops natural patina over time. For outdoor activities or humid climates, a robust cotton NATO or FKM rubber strap maintains performance without aesthetic compromise.

Use a spring bar tool (lug extractor): position the forked tip into the slots of the spring beneath the lug, apply gentle outward pressure to free the spring. Once released from one side, the strap slides away easily. Proceed carefully to avoid scratching the lugs. The operation takes less than two minutes.

Yes, provided the lug width is 19mm. Bespoke aftermarket straps are 100% compatible with the T101.917.11.031.00, as long as they are crafted with 19mm lugs. Milanostraps offers personalised straps in this size, with choice of premium materials and finishes tailored to your Tissot.

A high-quality leather strap with vegetable tanning, worn regularly, lasts 3–5 years before replacement is needed. Longevity depends on climate (humidity accelerates ageing), frequency of wear and maintenance: avoid prolonged water exposure, protect from excessive perspiration, apply leather conditioner every 12–18 months. The patina that emerges over time is desirable and adds aesthetic value.
