Strap for PRX Powermatic 80 Damian Lillard Special Edition

The lug width of the Tissot PRX T137.407.33.051.00 is 12mm. This narrow dimension is intentional and gives the model elegant proportions. Straps must be manufactured specifically for this non-standard attachment point, as generic 14mm or 16mm straps are incompatible. Measurement is conducted with a digital calliper between the lug shoulders, at the point where the lug fastens laterally to the case.

The ideal strap depends on intended use. For formal wear, black or dark brown alligator in vegetable tannage amplifies the constructive geometry of the PRX. For urban and sports contexts, vegetable-tanned box calf offers character and longevity. A NATO in natural cotton with naval tones maintains aesthetic rigour. Nitrile FKM rubber is the technical choice for authentic use, requiring no maintenance and visually coherent with the industrial design language.

The Tissot PRX features standard bayonet attachments on both case flanks. Use a spring bar tool, gently insert the tip beneath the lug and lift until the internal spring yields. Once the spring releases, fully extract the pin. Repeat on the opposite side. For mounting the new strap, position the pins in the corresponding seats and press until the click engages. Never force the spring beyond its natural travel range.

Yes, provided they respect the 12mm lug width specification. Specialist strap manufacturers, such as Milano Straps, offer non-standard attachments in alligator, calf and rubber specifically configured for the PRX. Generic and mass-market straps, typically manufactured for 14mm or larger dimensions, are incompatible. Always verify technical specifications before purchase.

A vegetable-tanned leather strap, with moderate daily use and proper maintenance, lasts approximately 18–36 months. Longevity depends on usage intensity, exposure to moisture and tannage quality. Premium alligator maintains structural integrity even after three years. Applying protective balms every 4–6 months extends useful life and preserves patina development. FKM rubber has no biological expiration and remains functional for years.
