Frequently asked questions

What is the lug width of the Tissot PRX T137.407.16.051.00?

The Tissot PRX T137.407.16.051.00 features a lug width of 12mm. This dimension is specific to the integrated bracelet design of the PRX model and results from the architectural proportions of the case. To measure it accurately, position a digital calliper from the inside of one lug to the inside of the other, excluding any decorative protrusions. This measurement is essential for selecting aftermarket straps specifically engineered for this width.

What is the best strap for the Tissot PRX T137.407.16.051.00?

The optimal choice depends on intended usage and aesthetic preference. For maximum elegance, alligator with fine grain complements the minimalist geometry of the case perfectly. Vegetable-tanned calf leather offers equilibrium between sophistication and practicality, developing natural patina over time. For dynamic environments, butyl rubber with fine grain texture ensures moisture resistance and flexibility. NATO straps in Jacquard canvas represent a creative alternative that enhances the geometric character of the PRX. The ideal selection reflects your daily usage pattern and personal style.

How do I change the strap on the Tissot PRX T137.407.16.051.00?

The Tissot PRX T137.407.16.051.00 features specific 12mm lug attachments. To perform the change, use a professional pin remover tool, available from authorised dealers or online retailers. Insert the tool into the small lateral hole where the strap connects to the case, apply gentle pressure and the pin will slide out. Repeat on the opposite side. When inserting the new strap, ensure pins are perfectly aligned and the strap is securely fastened. If uncertain, consult a professional watchmaker to prevent case damage.

Are there aftermarket straps compatible with the Tissot PRX T137.407.16.051.00?

Yes, premium aftermarket straps engineered specifically for the 12mm lug width of the PRX T137.407.16.051.00 are available. Milano Straps offers a curated selection of artisanal straps in alligator, calf, NATO and rubber, all manufactured to fit precisely this width specification. These straps maintain high quality standards and allow you to personalise the watch whilst preserving the integrity of the original design. Compatibility is guaranteed by technical conformity to the 12mm lug width and absence of invasive case modifications.

How long does a leather strap last on the Tissot PRX T137.407.16.051.00?

Leather strap durability depends on usage intensity, environmental conditions and maintenance practices. A quality alligator or vegetable-tanned calf strap with artisanal construction typically lasts 3-5 years under moderate daily use. In more dynamic contexts or with frequent moisture exposure, longevity may decrease to 2-3 years. Critical factors include perspiration, solar exposure and drying procedures following water contact. To extend strap lifespan, avoid prolonged water exposure, dry thoroughly if wetted and apply protective treatment occasionally. Rubber straps, conversely, offer extended durability (5-7 years) with minimal maintenance requirements.
