FAQ

What is the lug width of the Tissot PR516 T149.459.21.051.00?

The lug width of the Tissot PR516 T149.459.21.051.00 is 20 mm. This measurement refers to the internal distance between the pins that pass through the case at the lug positions. It is essential to verify that the chosen strap has precisely 20 mm width, measured at the points closest to the case bezel.

What is the best strap for the Tissot PR516?

The best strap depends on intended use. For formal elegance, an alligator or shell cordovan strap with vegetable tanning is recommended, developing a rich patina over time. For daily wear, full grain leather with vegetable tanning offers authentic tactile and visual quality. For aquatic or sports environments, a butadiene rubber strap guarantees waterproofness and thermal comfort. NATO straps in sturdy nautical fabric represent a versatile compromise for varied usage patterns.

How do I change the strap on a Tissot PR516 T149.459.21.051.00?

To change the strap, first remove the old strap by extracting the pins from the lugs using a dedicated tool (spring bar tool or watch tool set). Position the watch with the dial facing downward, supported on a soft surface. Locate the pin access point, insert the removal tool, and apply gentle outward pressure. Once the pins are removed, the previous strap can be slid from the lugs. Align the new 20 mm strap with the lugs and reposition the pins, ensuring the seat is completely correct before applying final pressure.

Are there aftermarket straps compatible with the Tissot PR516?

Yes, the Tissot PR516 is compatible with numerous aftermarket straps featuring 20 mm width. The market offers options in full grain leather, alligator, shell cordovan, NATO fabric straps, and butadiene rubber straps for sports use. Selecting specialised craft manufacturers allows you to obtain straps constructed to superior quality standards compared to original Tissot straps, while maintaining absolute structural compatibility with the case lugs.

What is the average lifespan of a leather strap for the Tissot PR516?

The lifespan of a leather strap depends on construction quality and leather type. A full grain strap with vegetable tanning, subjected to moderate daily use, has an average lifespan of 3–5 years before replacement is required. Shell cordovan, owing to its unique molecular structure, can remain functional for 7–10 years or longer. Premium alligator or crocodile straps offer lifespan comparable to cordovan. Prolonged water exposure, frequent perspiration, and direct sunlight significantly reduce longevity. Periodic maintenance (gentle cleaning, annual conditioning) extends useful life by 2–3 years.
