FAQ

What is the lug width of the Tissot PRX T137.407.11.041.00?

The lug width of the Tissot PRX T137.407.11.041.00 is 12 millimetres. This measurement represents the internal distance between the two lateral lugs of the case where the strap is attached. Precise measurement is essential to ensure the strap sits correctly without slipping or excessive tension.

Which strap is best suited for the Tissot PRX T137.407.11.041.00?

The Tissot PRX, given its minimalist brutalist aesthetic, pairs excellently with alligator straps using vegetable tanning for a sober, formal appearance, high-quality calf leather for everyday comfort, or heavy-duty canvas NATO straps for a sportier interpretation. Your choice depends on daily use and desired tone: understated elegance, daily comfort, or casual versatility.

How do I change the strap on the Tissot PRX T137.407.11.041.00?

Strap replacement is straightforward: position the watch on a soft surface, locate the spring bar on the original strap, and use a spring bar tool to press the elastic pin, allowing the old strap to be extracted. Insert the new strap in the same manner, ensuring the pin clicks firmly into position. If uncertain, consult a specialised service centre.

Is the Tissot PRX T137.407.11.041.00 compatible with quality aftermarket straps?

Yes, the Tissot PRX T137.407.11.041.00 is fully compatible with quality aftermarket straps, provided they feature the correct 12-millimetre lug width. High-quality alligator, shell cordovan, calf, NATO, and rubber straps offer durability, aesthetic appeal, and functionality equal to or superior to the original Tissot strap.

How long does a leather strap last on the Tissot PRX T137.407.11.041.00?

Leather strap lifespan depends on material type and frequency of use. Alligator and shell cordovan with vegetable tanning offer 4–6 years of daily wear if properly maintained, developing attractive patina over time. Quality calf lasts 2–4 years. Rubber and NATO straps are more durable, easily exceeding 5–7 years. Periodic cleaning and rest periods significantly extend operational life.
