Strap for PRX Quartz 25 Stainless Steel / MOP

The lug width of the Tissot PRX T137.010.11.111.00 is 8mm. This dimension, measured from inner edge to inner edge of the lugs, is specific to Tissot's integrated case design for the PRX family. Any compatible strap must be exactly 8mm wide to ensure a snug fit without lateral play.

The ideal strap depends on your use case and personal style. For formal elegance, we recommend vegetable-tanned alligator in neutral tones (black, grey, cognac). For daily versatility, a grained calfskin in brown or black maintains artisanal quality and adaptability. For casual wear, a textured NATO strap in grey or navy blue respects the functional ethos of PRX design.

The PRX uses standard spring bar attachments. Insert a spring bar tool into the small opening beneath the case, press the tiny internal pin to release the spring, and the old strap detaches. Reverse the operation with your new 8mm strap. If you're not experienced with this, Casati Milano's atelier offers professional strap replacement by appointment.

Yes. Any strap with an 8mm lug width is compatible with the Tissot PRX T137.010.11.111.00, provided it is crafted by qualified artisans. Milano Straps curates a selection of 8mm straps in leather, NATO, and rubber—each tested to guarantee perfect fit and durability.

Durability depends on material quality and usage patterns. A high-quality artisanal alligator or calfskin strap, worn daily under normal conditions, will last 3–5 years before visible signs of wear emerge. Vegetable-tanned leather develops a natural patina over time, increasing aesthetic appeal. Prolonged sun exposure, salt water, or excessive humidity accelerates ageing.
