Strap for PRS 516 Powermatic 80 Stainless Steel / Silver / Bracelet

The lug width of the Tissot PRS 516 T100.430.11.031.00 is 20 millimetres. This dimension was selected by Tissot's design team to achieve correct proportions between the 45mm case and the wrist. You can verify this measurement using a digital calliper on the flat base of the lug attachment: the value should fall between 19.8 and 20.2mm to ensure a precise fit without excessive play.

The ideal strap depends on your personal style and intended use. For understated elegance, we recommend alligator in slate-grey or tobacco tones, which creates sophisticated contrast with the ceramic case. For versatility and visible ageing, vegetable-tanned calf leather in cognac or burgundy offers aesthetic maturation over time. For sports activities or aquatic environments, FKM rubber or NATO canvas in black preserves the original racing character of the watch.

The strap on the PRS 516 T100.430.11.031.00 is changed using a specialised tool called a spring bar tool. Position the watch with the lug attachment facing you, insert the flat tip of the tool into the small gap on the side of the lug to compress the internal spring, then withdraw the strap. Repeat on the other side. To install the new strap, align the two holes with the spring lugs and push gently until you hear a click.

Yes, a wide range of 20mm aftermarket straps are compatible with the Tissot PRS 516 T100.430.11.031.00. At Milano Straps you will find straps in alligator, shell cordovan, vegetable-tanned calf, NATO canvas and FKM rubber, all constructed to artisanal standards and ready for dispatch. The 20mm dimension, although intermediate compared to more common standards (18mm and 22mm), nevertheless offers a rich variety of customisation options.

The lifespan of a leather strap depends on construction quality, tanning method and intensity of use. A high-quality artisanal strap in vegetable-tanned calf or alligator leather, worn daily, maintains optimal performance and pleasant aesthetics for 24–36 months. If worn intermittently or stored away from humidity and direct light, it can last 4–5 years. FKM rubber and NATO straps offer superior durability, easily exceeding 5–7 years of intensive use.
