Frequently asked questions

What is the exact lug width of the Tissot PRS 516 T91.1.488.51?

The lug width of the Tissot PRS 516 T91.1.488.51 is 20mm. This measurement is taken from the centre of the entry hole to the centre of the exit hole, excluding the thickness of the spring bars. It is essential to verify this dimension before purchasing an aftermarket strap to ensure mechanical and aesthetic compatibility.

What is the best strap for the Tissot PRS 516 T91.1.488.51?

The choice of strap depends on intended use. For sporty-formal elegance, a dark brown alligator or black calf leather. For intensive daily contexts, grey or navy blue vulcanised rubber. For economic versatility and seasonal rotation, grey or beige cotton NATO. What matters is maintaining the 20mm lug width and a constructive profile consistent with the proportions of the PVD case.

How do you change the strap on a Tissot PRS 516 T91.1.488.51?

The Tissot PRS 516 uses standard spring bars. To replace the strap: remove the spring bars (the small metal pin that holds the strap in the lugs) using a dedicated tool or small screwdriver, extract the old strap, insert the new spring bars into the new strap, then position the new strap by aligning the holes with the case lugs and press until it clicks into place. Approximately 2-3 minutes per side.

Are aftermarket straps compatible with the Tissot PRS 516 T91.1.488.51?

Yes, provided the lug width is 20mm. High-quality aftermarket straps (genuine alligator, shell cordovan, vegetable-tanned calf) often offer superior aesthetic and tactile upgrades compared to factory standards. Verify that the strap is manufactured with robust spring bars (satin nickel or stainless steel) and that the stitching is regular and well-executed.

What is the estimated lifespan of a leather strap for the Tissot PRS 516 T91.1.488.51?

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts 3-5 years of moderate daily use, with a patina curve (darkening and softening) beginning after 3-6 months. Factors such as humidity, perspiration, sunlight exposure and frequency of use affect longevity. Regular maintenance (cleaning, annual conditioning) extends the strap's serviceable life.
