Strap for PRX Quartz 25 Stainless Steel / Ice Blue

The lug width of the Tissot PRX T137.010.11.351.00 is 8mm. This narrow measurement is characteristic of compact, small-case watches and is critical for selecting any aftermarket strap. To measure correctly, place a ruler between the internal lugs: the distance must be exactly 8mm. No margin for error is permitted, as a strap calibrated for a different width will not fit the lugs properly.

The ideal strap depends on your use case and aesthetic preference. For maximum refinement, alligator leather with vegetable tanning subtly dialogues with the brushed case, developing patina over time. Barenia calf offers superior tactile softness and chromatic versatility. NATO straps deliver practicality without sacrificing elegance, whilst FKM rubber is recommended for sportier applications. All options must respect the 8mm lug width to fit properly.

Strap replacement requires a specialised tool called a spring bar remover. Position the watch with the lug facing upward, insert the remover into the small lateral holes of the lug to compress the internal spring, then extract the strap horizontally. Repeat for the lower lug. To install the new strap, align the strap holes with the lugs, insert the spring by compressing it with the remover, then release until the click engages. Verify the strap is securely fastened before wearing.

The Tissot PRX T137.010.11.351.00 accepts only straps with an 8mm lug width. Milano Straps offers a comprehensive collection of 8mm straps in different materials: alligator with vegetable tanning, Barenia calf, shell cordovan, cotton-polyester NATO, and FKM rubber. All straps are engineered to ensure proportions coherent with the 25mm case diameter, avoiding visual imbalance. The maximum strap thickness should not exceed 3mm for optimal lug engagement.

The lifespan of a leather strap depends on material quality, tanning method, and frequency of use. An alligator or calf strap with vegetable tanning can last 5–8 years of regular daily wear, developing characteristic patina that enhances aesthetic value over time. Vegetable-tanned leather requires periodic maintenance: avoid prolonged exposure to humidity and direct sunlight, and condition the leather every 6–12 months with specialised products. NATO fabric straps have similar durability, whilst FKM rubber can last 7–10 years. Milano Straps recommends maintaining spare straps to extend the service life of individual pieces.
