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

The Tissot PR 100 T150.410.11.091.00 features a lug width of 20mm. This measurement represents the internal distance between the case lugs and determines compatibility with aftermarket straps. To verify with precision, use a digital calliper, positioning it between the upper and lower barrel pins: the measurement must be exactly 20mm.

Selection depends on intended use. For a formal-classical context, alligator with vegetable tanning or calf leather with fine grain in cognac tonality amplifies case sobriety. For a sports approach, a NATO in ballistic canvas navy blue generates aesthetic coherence with Tissot heritage. For dynamic or marine environments, synthetic rubber in anthracite grey offers maximum water resistance and tactile grip. Shell cordovan represents the rare choice of excellence, with vertical grain texture that does not visually compete with case geometry.

The procedure is straightforward: obtain a spring bar removal tool or a robust thin needle. Position the watch on a stable surface, gently place the tool on the barrel of the spring bar to be removed, and push toward the centre until the pin releases from its seat. Remove the used strap. Insert the new strap by aligning pins with seats, ensuring the barrel engages correctly on both sides. Do not force: proper insertion requires restrained and symmetrical pressure. The screw crown remains intact during the operation.

Yes, all straps constructed for 20mm lug width are compatible with the T150.410.11.091.00. However, verify: 1) the declared width is genuinely 20mm, not 19.5mm or 20.5mm (variances of 0.5mm prevent stable accommodation); 2) strap thickness does not exceed 4.5mm near the lug area to prevent friction against the case; 3) total length is sufficient for your wrist, considering the 40mm case requires straps of approximately 240mm. Straps in alligator, calf, NATO, and rubber are routinely compatible.

Leather strap longevity varies based on tanning type, thickness, climate, and frequency of wear. Calf with vegetable tanning tends to patina and stiffen after 18–24 months of daily wear, losing flexibility. Superior-quality alligator extends this duration to 2–3 years. Humid environments, chlorine, and sea salt accelerate deterioration. To maximise useful life: avoid prolonged water exposure, apply leather conditioner every 4–6 months, store the watch in controlled humidity (35–65%). A NATO or rubber strap exhibits no biological degradation and remains functional indefinitely, barring mechanical failure.
