Strap for PR516 Powermatic 80 Stainless Steel - Yellow Gold / White / Bracelet

The lug width (ansa width) of the Tissot PR516 T149.407.22.011.00 is precisely 20 millimetres. This measurement, taken from the inside of one lug attachment to the inside of the other, is a rare dimension in the contemporary market that reflects the compact proportions of the 38-millimetre case. Standard aftermarket straps (18, 19, 22 mm) are not compatible: a bespoke solution is required to achieve the correct interface between lugs and strap.

The choice depends on intended usage. For formal and refined daily contexts: dark brown alligator or vegetable-tanned calf leather. For technical use and humid environments: NATO in cotton gabardine or structured rubber. Alligator communicates well with the formal geometry of the case, while vegetable-tanned calf permits a natural patina over time. Avoid saturated chromatic straps: the PR 516 demands chromatic restraint.

The strap is removable via spring bars. Use a dedicated spring bar removal tool to press the bars inward toward the case, sliding them out with gentle movements. Never force: the bars are miniature components and excessive force damages the lugs. Insert the new strap into the prepared holes until the bars engage fully. If inexperienced, consult a professional watchmaker or Casati Milano atelier by appointment.

Yes. MilanoStraps offers a collection of artisanal 20mm straps, including alligator, vegetable-tanned calf, NATO in cotton, and structured rubber. Compatibility is certified on lug width (20 mm). Customisation in colour, buckle, lug style, and texture is available through direct consultation. No generic mass-market strap from standard e-commerce platforms is proportioned to this lug width.

Durability depends on material and usage patterns. Vegetable-tanned calf, worn in rotation with other timepieces (not daily), typically guarantees 3–4 years of use before significant structural degradation begins. Alligator, denser and more resilient, can last 5–6 years under the same conditions. Factors reducing longevity: constant humidity, frequent perspiration, direct sunlight exposure. Proper maintenance (occasional cleaning with a damp cloth, storage in dry environments) significantly extends strap lifespan.
