Strap for PRS 516 Quartz Chronograph 40 Stainless Steel / Silver / Bracelet

The lug width of the Tissot PRS 516 T91.1.488.31 is 20 millimetres. This dimension represents the net distance between the case lugs where the strap is inserted. It is essential to verify this measurement before purchasing an aftermarket strap, as an incorrect lug width will prevent proper fitment and compromise both aesthetics and wearing comfort.

For the PRS 516 T91.1.488.31, we recommend primarily alligator straps with vegetable tanning, structured calf leather, NATO textile straps, and vulcanised rubber straps. The choice depends on intended use: alligator and calf for formal or elegant everyday wear, NATO for sporting and military heritage appeal, rubber for water resistance and high-humidity activities. All materials must measure exactly 20 millimetres in width to ensure precise fitment with the lugs.

Changing the strap on the PRS 516 T91.1.488.31 requires specific tools: a spring bar tool or pin remover. Position the watch on a soft surface, insert the tool into the lateral gaps of the case lugs to release the spring, remove the old strap, and whilst maintaining pressure on the spring with the tool, slide the new strap (20mm) into place. Verify that the strap is centred and both springs click securely. If inexperienced, consult a qualified watchmaker.

Yes, any quality strap with a lug width of precisely 20 millimetres is compatible with the T91.1.488.31. Milanostraps offers an exclusive selection of 20mm straps in alligator, calf, NATO textile, and rubber, all handcrafted and ready to ship. Compatibility is guaranteed by standardised lug width; however, we recommend verifying the technical specifications of your chosen strap to ensure optimal fitment in terms of thickness and overall length.

The lifespan of a leather strap—alligator, calf, or shell cordovan—varies according to intensity of wear, sun exposure, and climate conditions. A strap worn daily in temperate climate has a useful life of 3–5 years before replacement is necessary. Vegetable-tanned alligator tends to develop an attractive patina, extending aesthetic interest beyond five years. Regular maintenance—avoiding prolonged water immersion, cleaning with soft cloth, and occasionally conditioning with natural leather cream—significantly extends strap longevity.
