Strap for PR 100 Sport Gent Chronograph Stainless Steel / Black / Bracelet

The lug width of the Tissot PR 100 T101.617.11.051.00 is 22mm. This measurement is taken by positioning a calliper between the two junction points where the lugs meet the case. A compatible strap must have an external width of 22mm to ensure perfect fit without tension or play. Variations of even ±1mm will cause poor fit and risk of strap detachment during wear.

The ideal strap depends on intended use. For everyday elegance, we recommend vegetable-tanned leather with light pebbled grain in brown or navy blue. For summer or sports, a cotton NATO offers breathability and quick changes. For maximum refinement, African alligator with a deployante clasp enhances the chrono's sport-elegant character. FKM rubber remains the ideal choice if you frequently alternate with water-based activities.

Strap replacement requires a spring bar tool (two-pronged implement) or a very thin flathead screwdriver. Position the tool in the groove separating the lug from the case, push inward to release the spring bar pin, then extract the old strap. Insert the new strap into the upper lug, position the spring bar pin in the lower lug slot and press until you hear an audible click. Repeat for the opposite side. Avoid using overly wide screwdrivers to prevent scratching the case.

Yes, any 22mm aftermarket strap is compatible with the Tissot PR 100 T101.617.11.051.00. We recommend specialist brands that guarantee precise manufacturing tolerances: straps with standard rectangular lugs (5mm internal width) and thicknesses between 3-5mm fit perfectly. Verify that the strap uses an external spring bar mounting system (not glued) and that the material does not bleed dyes onto the dial if exposed to rain.

A premium leather strap with vegetable tanning and thickness exceeding 3.5mm typically lasts 3-5 years of daily wear before losing elasticity at the attachment points. Longevity depends on water exposure, the wearer's sweat pH, and maintenance (mink oil applied every 12-18 months significantly extends life). Alligator resists longer (7-10 years) due to lower hygroscopicity. Cotton NATO straps last 2-3 years before stitching loosens. FKM rubber has similar lifespan to leather but degrades with prolonged UV exposure.
