Strap for PRS 516 Automatic 40 Stainless Steel / Black / Bracelet

The lug width of the Tissot PRS 516 T91.1.483.51 is 20 millimetres. This dimension is the standard for this 40mm sports chronograph model and corresponds to the internal distance between the case lugs. Any aftermarket strap must strictly respect this specification to ensure a proper fit without play.

There is no universal choice—it depends on intended use and aesthetic preferences. Natural alligator offers sophistication whilst maintaining sporty identity. Vegetable-tanned calf combines elegance with daily durability and develops patina over time. Cotton NATO provides immediate comfort and practicality with varsity aesthetics. FKM rubber is ideal for marine environments or sporting activities. Each material tells a different interpretation of the same chronograph.

The process requires a dedicated tool to extract the spring bars that secure the strap to the case lugs. Position the watch on a stable surface with the strap facing downward. Insert the small end of the tool under the strap pass and gently press upward to release the spring. Repeat on the opposite side. Once the old strap is removed, insert the new strap's bars, align them perfectly with the case holes, and press until they click. Always verify that the strap is 20mm.

Yes, any aftermarket strap with a 20mm lug width is compatible with the T91.1.483.51. Compatibility is guaranteed by the standardisation of width, regardless of strap brand. It is essential to verify the lug width before purchase: undersized (18mm) or oversized (22mm) straps will not insert correctly into the case lugs.

The lifespan of a leather strap depends on use, maintenance, and material quality. A high-quality alligator or calf strap, used daily, typically lasts 3-5 years before requiring replacement. Prolonged exposure to moisture and perspiration accelerates wear. Vegetable-tanned leather develops natural patina that enhances character over time. Regular maintenance—drying after rain, avoiding immersion—significantly extends strap lifespan.
