Strap for PRX Digital 35 Stainless Steel / Black

The lug width (strap attachment width) of the Tissot PRX T137.263.11.050.00 is 10mm. This measurement represents the internal distance between the integrated lugs of the case. It is essential to verify this dimension accurately using a digital calliper positioned perpendicular to the lugs, ensuring the strap fits without lateral play or misalignment.

There is no universally 'best' strap as it depends on the intended use case. For formal occasions, we recommend alligator or Taurillon calf leather with vegetable tanning, which enhance the minimalist proportions of the case. For daily versatile wear, heavyweight cotton NATO straps offer practicality and aesthetic reversibility. For aquatic activities, fluoroelastomeric rubber solutions ensure durability and water resistance. Milano Straps supplies all these materials pre-shaped in 10mm lug width.

Strap replacement requires a sprung bar tool to compress the spring-loaded pins that connect the strap to the lugs. Insert the tool into the designated groove on each lug, release the pin, and slide out the old strap. Position the new 10mm strap, align the holes, and reinstate the pins, ensuring symmetrical placement. If unfamiliar with the procedure, professional watch service centres are recommended for safe installation.

Yes, the 10mm lug width is compatible with numerous aftermarket straps. Milano Straps specialises in this measurement with a dedicated collection including leather (alligator, calf, shell cordovan), NATO in various fabrics, and technical rubber. All straps are pre-shaped and ready for installation, with bespoke customisation available through Casati Milano atelier by appointment.

The longevity of a leather strap depends on material type and tanning method. Vegetable-tanned alligator may last 5-10 years with proper care (regular cleaning, limited exposure to prolonged moisture). European calf leather has similar durability, whilst shell cordovan, due to its natural density, can exceed 10-15 years. Primary wear concerns the buckle and keeper loops; the strap leather develops an aged patina that enhances aesthetic value. Rotating between multiple straps distributes mechanical stress and extends individual strap lifespan.
