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

The lug width of the Tissot PRX T931.407.41.031.00 is 12 millimetres. This dimension represents the outer distance between the integrated case lugs and determines compatibility with aftermarket straps. Measurement should be verified using a digital calliper positioned perpendicularly to the watch plane, at the lug seat.

For the T931.407.41.031.00, we recommend alligator straps in cognac or tobacco tones, which amplify the Seventies brutalist heritage and complement the rose gold and steel case perfectly. Alternatively, vegetable-tanned calf for minimalist aesthetics, slate-grey NATO for contemporary styling, or vulcanised rubber for water-resistant applications.

The T931.407.41.031.00 uses integrated case lugs. Proceed as follows: position the watch on a work stand; identify the spring bars at each lug; extract the old strap using a small spring bar tool, pressing downward gently; align the new 12mm strap with the lugs and insert the bars until they click into place. Do not force: uniform, gradual pressure is sufficient.

No. Although lug width is 12mm, straps must meet precise construction specifications: leather thickness compatible with integrated lugs (maximum 1.8–2mm), absence of protruding lateral stitching, buckle or deployant clasp not exceeding 16mm width. Milano Straps bespoke straps are calibrated precisely to this geometry.

A quality alligator or calf strap, if worn regularly, maintains structural and aesthetic integrity for 3–5 years. Durability depends on frequency of wear, solar exposure, humidity, and care (periodic cleaning with damp cloth, natural drying). Vegetable-tanned leathers develop patina and appeal with age, whilst rubber straps offer superior resistance in marine environments.
