Strap for PR516 Chronograph Quartz Stainless Steel / Black / Bracelet

The Tissot PR516 (reference T149.417.11.051.00) features a lug width of 20mm. This measurement is standard across the PR516 family and permits the use of straps of superior manufacturing quality, as the space accommodates double stitching and tailored finishes without compromise. The 20mm width is the European military and railway standard, originating from field chronographs of the 1970s and 1980s.

The best strap depends on the intended use. For formal or professional contexts, we recommend an alligator strap in black or cognac brown (thickness 1.2–1.4mm), which maintains elegance without betraying the technical heritage of the PR516. For daily wear, a strap in vegetable tanning with a thickness of 1.6–1.8mm offers natural ageing patina and superior resistance. For aquatic or extreme environments, a vulcanised FKM rubber strap remains the supreme technical solution. NATO canvas straps in Cordura preserve the model's military identity.

The Tissot PR516 strap is changed by removing the spring bars—the two small metal pins that hold the strap in position beneath the lugs. Use a dedicated tool (spring bar tool) to apply pressure inward on one pin, lifting the strap end. Repeat the operation on the other pin. Once the spring bars are removed, the old strap detaches completely. Position the new strap on the first lug, maintain the first spring bar in position with the appropriate lever, and push gently until the click engages. Repeat on the other lug. If you lack the tools, contact Atelier Casati Milano for in-house replacement.

Yes, any strap equipped with lugs (attachment spaces) suitable for a 20mm width is compatible with the Tissot PR516. MilanoStraps artisanal straps, crafted with variable thicknesses (1.2mm for alligator, 1.6–1.8mm for calf or vegetable-tanned leather) and available with standard spring bars or deployante clasps, fit the PR516 perfectly. Compatibility is guaranteed by precise measurement of the 20mm lug width. Avoid generic industrial-production straps: prefer manufacturers that measure lugs with a digital calliper.

The lifespan of a leather strap depends on tanning quality, thickness, and frequency of wear. A vegetable-tanned strap of 1.6–1.8mm thickness (as produced by MilanoStraps) lasts an average of 4–6 years with daily wear, developing a highly appreciated ageing patina. Alligator, more resilient and less porous, may last 5–7 years. Shell cordovan, owing to its dense fibrous nature, can exceed 10 years. Durability increases considerably if the strap is not exposed to constant moisture (avoid prolonged contact with fresh or salt water). Periodically apply a protective cream based on lanolin. Atelier Casati Milano offers restoration services and component replacement (spring bars, lugs, stitching) to extend the strap's life.
