Strap for PRX 35 Powermatic 80 Stainless Steel - Rose Gold / Grey - Diamond

The lug width of the Tissot PRX T931.207.41.336.00 is precisely 11 millimetres. This measurement reflects the compact proportions of the 35mm case and integrated lugs within the bezel design. It does not conform to conventional standards (18-20mm American or 24mm European), therefore replacement straps must be specifically calibrated to fit the case without slack or mechanical instability.

For the Tissot PRX T931.207.41.336.00, we recommend alligator leather with vegetable tanning or calf leather, which respect the sober and geometric character of the design. Bourbon or dark brown alligator creates tonal consonance with the rose gold case, whilst black or anthracite-grey leather produces elegant contrast by emphasising material duality. For sport use, a black fine-grained rubber strap offers practicality without aesthetic compromise.

Strap replacement requires a specialised tool (spring bar remover or lug attachment tool) to apply pressure to the pins securing the strap in the case lugs. Position the spring bar perpendicularly to the tool and apply gradual pressure until complete detachment. Insert the new strap by aligning its lugs with the case guides, then reinsert the pins with reverse motion until locking is confirmed. We recommend entrusting this operation to qualified professionals to avoid scratching the bimetallic case.

Yes, aftermarket straps in 11mm lug width are available from specialised retailers such as Milano Straps. These straps offer varied materials (alligator, shell cordovan, vegetable-tanned calf, NATO, rubber) whilst maintaining dimensional compatibility with the case lugs. It is essential to verify that the lug width is exactly 11mm to prevent misalignment or damage to the case guides.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 5-7 years with daily wear, accounting for natural fibre degradation from flexion, perspiration, and climatic variation. Vegetable tanning promotes controlled ageing, developing patina without structural deterioration. Factors such as frequency of use, solar exposure, humidity, and maintenance significantly influence longevity. A rubber FKM strap retains elastic properties for 10-15 years.
