Frequently asked questions

What is the exact lug width of the Tissot PRX T931.207.41.111.00?

The lug width of the Tissot PRX T931.207.41.111.00 is precisely 11mm. This narrower dimension, compared to contemporary standards (16-20mm), is a direct consequence of the watch's slim, integrated case design. To verify strap compatibility, measure the perpendicular distance between the inner edges of the lugs using a digital calliper.

Which strap material is best suited for the Tissot PRX?

For the PRX T931.207.41.111.00, we recommend alligator or vegetable-tanned calf leather for formal elegance, or synthetic NATO textile straps for daily practicality. Butyl rubber is ideal if you use the watch in humid environments. Your choice depends on the intended context and the maintenance level you're willing to commit.

How do you change the strap on a Tissot PRX?

Strap replacement requires a specialist tool (spring bar tool or pin remover). Locate the two lugs beneath the case, insert the tool into the lateral aperture to compress the internal spring, then gently extract the old strap. Repeat the procedure to install the new one, ensuring the lugs seat completely within the strap slots. If you lack experience, consult a specialist atelier such as Casati Milano.

Can I use a custom-made aftermarket strap on the PRX T931.207.41.111.00?

Yes, entirely. The 11mm lug width permits complete customisation via artisanal straps. Consult an atelier that understands the model's technical specifications: the narrower lug width demands greater manufacturing precision. Milano Straps offers a curated selection of 11mm-compatible straps, customisable online or through Casati Milano's bespoke service by appointment.

What is the typical lifespan of a leather strap on a watch like the PRX?

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3–5 years with moderate daily wear, extending to 7–8 years if worn intermittently or in dry environments. Longevity depends on exposure to moisture, heat, and mechanical stress. Routine maintenance (conditioning with specialist oils, rapid drying after water contact) significantly extends strap life.
