Strap for PRC 100 Quartz 41.3 Stainless Steel / Black / Bracelet

The lug width (also called ansa width) of the Tissot PRC 100 T22.1.581.51 is 20mm. This measurement is taken between the lateral fixing pins of the case using a digital calliper; the value should fall between 19.8 and 20.2mm. Incorrect measurement is the primary cause of aftermarket strap incompatibility. MilanoStraps provides detailed dimensional guides to verify accuracy before purchase.

The Tissot PRC 100 T22.1.581.51 pairs excellently with three strap categories in 20mm: (1) Alligator with vegetable tanning in brown or black tones, emphasising the formal-sport character of the case; (2) NATO in Cordura canvas or cotton, ideal for daily wear and warm climates; (3) Shell Cordovan, for those appreciating leather ageing and colour stratification over time. Choice depends on intended use and dial colouration.

To replace the strap you will need a spring bar tool and the new 20mm strap. Procedure: (1) Place the watch on a soft surface; (2) Insert the spring bar tool under the lateral pin, pushing outward to release the spring; (3) Extract the pin from the case; (4) Repeat on the other side; (5) Align the new strap's holes with the case extremities; (6) Reinsert the pins using the tool until locked. Perform symmetrically on both sides. If inexperienced, consult a professional watchmaker to avoid case damage.

Yes, provided the strap is specifically dimensioned at 20mm and the fixing pins are of correct length (typically 16-18mm for this watch category). MilanoStraps guarantees full compatibility with reference T22.1.581.51 as straps are manufactured and tested to case dimensional specifications. Always verify that strap holes align precisely with case guides before purchase.

Leather strap longevity depends on material and usage frequency. An alligator strap with vegetable tanning, worn daily, typically lasts 4-7 years before visible wear appears at flex points. A smooth calf strap has similar lifespan but suffers more from UV exposure. Shell Cordovan is renowned for superior longevity (8-12 years) due to natural skin density. Ageing is part of the aesthetic: patina and wear marks impart character and personality over time, transforming the strap into a unique artefact.
