Strap for PRX Quartz Stainless Steel / Mint

The lug width of the Tissot PRX T137.410.11.091.01 is 12 millimetres. This dimension is specific to the model and represents the distance between the inner shoulders of the case lugs. Precise measurement is essential to ensure compatibility with aftermarket straps and secure fastening via spring bars.

There is no universally 'best' strap; the choice depends on use and aesthetic preference. For formal elegance, we recommend alligator leather or shell cordovan. For daily versatility, a nylon NATO offers practicality and quick changes. For marine environments or high humidity, an FKM rubber strap guarantees durability without compromise. Vegetable-tanned leather develops an evolving patina over time.

The Tissot PRX uses standard 12-millimetre spring bars. Use a spring bar tool to gently compress the spring from inside the lug and slide the bar outward. Align the new bar with the seats and insert until it clicks into place. Avoid excessive force to prevent case damage. We recommend performing this operation on a soft surface to protect the crystal.

Any strap with a 12-millimetre lug width is compatible with the PRX T137.410.11.091.01, provided it is equipped with standard spring bars. milanostraps.it offers a curated selection of 12mm straps in various materials: calf leather, alligator, NATO, and rubber. Each item is tested to ensure correct fitting and absence of play.

Leather strap longevity varies based on material, frequency of use, and environmental conditions. Well-maintained calf leather with regular care lasts 3–5 years. Alligator or shell cordovan leather, being more structured, can exceed 7–8 years. Constant exposure to humidity, perspiration, and direct sunlight reduces lifespan. FKM rubber or nylon NATO straps have superior longevity, typically exceeding 10 years, without significant material degradation.
