Strap for PRX Quartz Stainless Steel / Full Lume/ Rubber

The Tissot PRX T137.410.17.011.00 features an integrated attachment of precisely 12 millimetres in width. This dimension is a defining design characteristic of the PRX family and requires straps manufactured to this exact specification. To verify compatibility, measure the distance between the two internal edges of the case using a ruler: it must correspond precisely to 12mm.

For the Tissot PRX T137.410.17.011.00, we recommend straps in natural alligator with vegetable tanning, Swiss-quality soft calf leather, or military-grade NATO fabric. Selection depends on purpose: alligator enhances sporting elegance; cognac-brown calf creates balanced warm-cool contrast; NATO introduces contemporary chromatic versatility. For humid environments, certified rubber performs ideally. All must strictly respect the 12mm lug width.

The Tissot PRX T137.410.17.011.00 utilises an integrated 12mm attachment system without conventional lugs. To change the strap, open the caseback using the appropriate tool (the same key used for the original integrated bracelet) and carefully extract the internal fixing mechanism. A compatible 12mm strap inserts directly into this structure. We recommend Atelier Casati Milano's service to ensure millimetre precision and case integrity.

All straps manufactured with 12mm lug width are compatible. On milanostraps.it you will find: natural alligator straps, Italian calf leather, NATO fabric, certified rubber—all customisable and crafted for this specific measurement. Avoid generic 12mm straps that do not respect the geometry of the case's integrated attachment; even minor deviations cause wrist instability or damage to internal contact points.

A quality leather strap (alligator with vegetable tanning or European calf) maintains structural integrity for 3 to 5 years of daily wear, varying with wearing frequency, UV exposure, humidity, and maintenance. Natural leather develops a charming patina but visibly ages. A NATO strap lasts 5-7 years thanks to robust fabric. Rubber resists 4-6 years. To extend lifespan, apply nourishing balm every 6 months and store away from direct light when unworn.
