Strap for PRX Powermatic 80 Stainless Steel - Yellow Gold / Silver

The lug width of the Tissot PRX T931.407.41.031.01 is precisely 12.00 mm. This measurement refers to the distance between the inner lugs where the strap or bracelet attaches. This dimension is a defining characteristic of the PRX model, aligning it with the original 1970s design philosophy, and it requires careful consideration when selecting aftermarket straps.

For the PRX T931.407.41.031.01, we recommend three principal options: an alligator or crocodile strap with vegetable tanning for enhanced dress aesthetics; smooth calf leather in burgundy, cognac, or dark brown tones for an elegant-casual balance; or a nylon NATO strap in neutral satiny finishes for versatility and sporting character. Your choice should reflect your intended use and personal aesthetic preference between dress and sport.

Strap replacement requires a spring bar tool. Position the tool against one of the lug bars, gently push inward to release the pin from its seat, and repeat on the opposite side. Once both bars are freed, remove the old strap and carefully insert the new one, ensuring the bars are firmly secured in their new positions. If you lack experience, we recommend consulting a professional service such as Casati Milano atelier to prevent damage.

Yes, absolutely. Any aftermarket strap with a 12.00 mm lug width and aesthetic coherence with the PRX design is fully compatible and represents an excellent opportunity for personalisation and stylistic exploration. Milano Straps curates a selection of premium 12mm straps in noble materials with artisanal finishes specifically conceived for models such as the PRX.

A high-quality leather strap—alligator, calf, or shell cordovan—typically lasts 3 to 5 years of moderate daily use. Longevity depends on exposure to humidity, perspiration, UV radiation, and frequency of wear. A vegetable-tanned strap develops a natural patina over time, enhancing its character. NATO and rubber straps offer greater durability (7 to 10 years) owing to their resistance to environmental factors.
