The PRX T137.407.11.351.00, seen from the bench

The Tissot PRX T137.407.11.351.00 is a contemporary reinterpretation of a 1970s icon featuring a 40mm stainless steel case with brushed and polished finish. Equipped with the reliable ETA C07.111 quartz movement, it displays hours, minutes, seconds and date. This model requires a 12mm lug width, a specific dimension that maintains the elegant proportions of the 40mm case without visual imbalance. The integrated lugs connect seamlessly to the case, creating the distinctive aesthetic continuity that defines the PRX design philosophy.

Frequently asked questions

What is the lug width of the Tissot PRX T137.407.11.351.00?

The Tissot PRX T137.407.11.351.00 features a lug width of 12mm. This dimension is specific to the model and must be respected when choosing an aftermarket strap. The lug width is measured as the internal distance between the two terminals that connect to the case, excluding the vertical depth of the case itself.

What is the best strap for the Tissot PRX T137.407.11.351.00?

The choice depends on intended use and personal style. For sartorial elegance, we recommend alligator leather with vegetable tanning in dark tones (black, dark brown). For everyday versatility, vintage satined or brushed calf offers natural ageing and durability. For sportiness, FKM rubber or cotton NATO straps maintain the watch's contemporary DNA. All materials must be crafted with compatible 12mm lug width.

How do I change the strap on my Tissot PRX T137.407.11.351.00?

The Tissot PRX features integrated lugs. To replace the strap, remove the two lug terminals from the case using a dedicated spring bar tool. Once the terminals are extracted, the old strap slides off easily and the new one (always 12mm) is installed by reversing the procedure. If unsure, we recommend consulting a professional watchmaker.

Can I use an aftermarket strap on my Tissot PRX T137.407.11.351.00?

Yes, absolutely. Any artisanal strap with 12mm lug width is compatible with your PRX. Milano Straps offers customisable straps in various materials (alligator, calf, NATO, rubber) handcrafted to this specific width, guaranteeing perfect fit and superior construction quality compared to the original bracelet.

How long does a leather strap last on the Tissot PRX T137.407.11.351.00?

Durability depends on material, usage, and maintenance. A vegetable-tanned calf strap lasts 3–5 years with moderate wear, as natural ageing strengthens its structure. Alligator is more resilient (5–7 years). Regular treatments with natural balm or beeswax significantly extend longevity. A NATO or rubber strap has greater durability under intensive use conditions.
