A 12 mm calf strap, for every day. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions
Which strap is most suitable for the Tissot PRX T931.407.41.031.00?
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.
Can I use any 12mm strap on the Tissot PRX T931.407.41.031.00?
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.
How long does a leather strap last on a Tissot PRX T931.407.41.031.00?
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.
