The Heritage

The Tissot PRX Powermatic 80 Damian Lillard Special Edition T137.407.33.051.00 is a 40mm stainless steel sports watch with a contemporary reinterpretation of 1970s Swiss design aesthetics. It features the ETA C07.111 movement with hours, minutes, seconds and date display, a sapphire crystal with anti-reflective treatment, and 10 bar water resistance. The 12mm lug width is intentionally narrow, creating a harmonious visual balance between case and strap while requiring specialized aftermarket strap solutions.

FAQ

What is the lug width of the Tissot PRX T137.407.33.051.00?

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.

Which strap is best suited to the Tissot PRX T137.407.33.051.00?

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.

How do I change the strap on my Tissot PRX T137.407.33.051.00?

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.

Is the Tissot PRX T137.407.33.051.00 compatible with quality aftermarket straps?

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.

How long does a leather strap last on the Tissot PRX T137.407.33.051.00?

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.
