The Heritage

The Tissot PRX T931.407.41.041.00 is a 40mm stainless steel and rose gold watch featuring the ETA C07.111 automatic caliber with hours, minutes, seconds and date window. This neo-vintage contemporary design reinterprets 1970s integrated watches with a thin case, 100m water resistance and sapphire crystal with anti-reflective coating. The 12mm lug width is a defining characteristic of the PRX line, ensuring perfect proportions on the 40mm case while maintaining elegance and slenderness.

FAQ

What is the exact lug width of the Tissot PRX T931.407.41.041.00?

The lug width (or ansa width) of the Tissot PRX T931.407.41.041.00 is precisely 12 millimetres. This reduced measurement is integral to the neo-vintage design language and ensures elegant proportions on the 40mm case. To verify, use a calliper or ruler positioned between the two internal lugs of the case without forcing pressure.

Which strap is best suited to the Tissot PRX T931.407.41.041.00?

The optimal strap depends upon your personal aesthetic and intended usage. For pure elegance, we recommend alligator leather with vegetable tanning in dark brown or burgundy tones: the natural grain emphasises the model's luxury heritage. For versatility, a vitello calf leather strap in black offers understated sophistication and practicality. A NATO strap in cordura fabric is perfect for a casual-sportive approach during summer months.

How do I change the strap on the Tissot PRX T931.407.41.041.00?

The Tissot PRX T931.407.41.041.00 employs standard spring bars for strap changes. Working on a well-lit surface, use a dedicated spring bar tool to gently depress the spring on one side whilst extracting the bar. Repeat on the opposite lug. Align the new strap's holes with the spring bars and press until you hear an audible click. Never force the mechanism—proper movement should be smooth and secure.

Are there compatible aftermarket straps for the T931.407.41.041.00?

Absolutely. Any quality strap featuring a 12mm lug width is fully compatible with the Tissot PRX T931.407.41.041.00. Milano Straps offers a curated selection of artisanal straps in leather, alligator, shell cordovan, NATO and rubber—all available in the 12mm specification and specifically selected to complement the PRX's design language.

What is the lifespan of a leather strap on the Tissot PRX T931.407.41.041.00?

Longevity depends upon material composition and usage intensity. A vitello calf leather strap with vegetable tanning typically lasts 3-5 years of daily wear, developing a beautiful patina over time. Shell cordovan, owing to its superior construction density, easily achieves 7-10 years of service life. Exposure to perspiration, moisture and UV radiation accelerates ageing: store your strap in a dry environment when unworn. Regular conditioning with appropriate creams substantially extends its lifespan.
