Strap for PRX Digital 40 Yellow Gold / Champagne

The lug width of the Tissot PRX T137.463.33.020.00 is 12mm, a specific measurement for this model. Lug width is measured between the internal case attachments and is essential for compatibility and correct aesthetic proportions. Do not use straps of different widths (11mm or 13mm) as they will not fit properly.

For the Tissot PRX T137.463.33.020.00, we recommend black or dark brown alligator for a formal aesthetic, or vegetable-tanned leather for a contemporary look. A NATO strap respects the sportive-casual DNA of the case, whilst FKM rubber is ideal for humid environments. Your choice depends on daily wear and dress code context.

To change the strap on the Tissot PRX T137.463.33.020.00, use a spring bar tool to remove the elastic springs anchoring the strap to the case lugs. Reposition the spring, insert the new strap through the upper hole, then secure the spring in the lower hole. Ensure the springs are properly seated to prevent accidental loss.

A quality leather strap on a wristwatch typically lasts 3-5 years, depending on frequency of use and environmental conditions. Vegetable-tanned leather ages elegantly, developing a natural patina over time. FKM rubber has a longer lifespan (7-10 years), whilst cotton NATO straps can last indefinitely with proper care.
