Strap for PR 100 Sport Gent Stainless Steel / Silver

The lug width of the Tissot PR 100 T101.610.16.031.00 is 22mm. This measurement is taken from the base of the spring bar on one lug to the base of the spring bar on the opposite lug. Accurate measurement is essential when purchasing aftermarket straps to ensure proper fit and eliminate unwanted gaps between case and strap.

The choice depends on intended use and personal style. For sartorial elegance, we recommend vegetable-tanned leather in Tuscan calf or alligator. For sports wear, a NATO in cotton-polyester or FKM rubber maintains functionality and versatility. A strap in aged brown or cognac leather, 3.5mm thickness, represents the ideal compromise between aesthetics and durability for the PR 100.

For the T101.610.16.031.00 model, you must remove the spring bars from the lugs. Obtain a spring bar tool or a small flathead screwdriver. Insert the tool under the spring bar and push gently downward to release it from the lug. Repeat on the other side. Reverse the procedure with your new strap. If inexperienced, consult a watchmaker or our Casati Milano atelier by appointment.

Yes, provided it is specifically dimensioned for 22mm lug width. We always verify compatibility in every strap description. Lug width is the most critical technical specification: a 20mm or 24mm strap will not fit correctly. Our bespoke straps are crafted precisely at 22mm with a maximum tolerance of ±0.5mm guaranteed.

A quality vegetable-tanned strap, worn in rotation with others, typically lasts 3-5 years under normal conditions. If frequently exposed to moisture, chlorine, or perspiration, lifespan may reduce to 2-3 years. With proper care (rapid drying, occasional natural balm applications) and mindful wear, you can significantly extend strap longevity. The patina that develops is part of the beauty of vegetable tanning, not a defect.
