Strap for PRS 516 Extreme Automatic Leather

The lug width of the Tissot PRS 516 T079.427.26.057.00 is precisely 23mm. This dimension is specific to this model and derives from the calculated proportion between the 44.40mm case diameter and the teardrop lug geometry. To verify correct measurement, position a digital calliper perpendicularly into the internal lug seat, measuring from wall to wall inside where the strap engages the retaining spring.

Alligator leather with vegetable tanning represents the most versatile and refined choice for the PRS 516 T079.427.26.057.00, as the natural grain reflects the watch's geometric precision. For strictly sporting applications, vulcanised rubber offers superior grip in humid environments. Vitello box leather, with its durability and patina development over time, constitutes an excellent aesthetic and functional alternative. NATO straps are ideal for casual contexts and allow rapid replacement without tools.

To change the strap on the T079.427.26.057.00, you must use a specialised tool (springbar removal tool or strap removal device) to extract the metal pin that secures the strap to the lugs. Position the watch on a soft, stable surface, locate the small indent on the lug side, insert the tool, and apply gentle, continuous pressure until the pin withdraws completely. Once the old strap is removed, thread the new strap onto the same pin and reinsert it into the lugs until the retaining mechanism locks.

Yes, any strap with a 23mm lug width is perfectly compatible with the Tissot PRS 516 T079.427.26.057.00. Artisanal aftermarket straps of superior quality, crafted from alligator, vegetable-tanned calf, or vulcanised rubber, guarantee identical fitment to the original strap and often offer greater aesthetic and tactile customisation. Using an aftermarket strap does not affect the watch's warranty, as the strap is an easily replaceable component.

The lifespan of a leather strap depends on the tanning method and intensity of use. An alligator or shell cordovan strap with vegetable tanning, subjected to moderate use and basic maintenance (periodic cleaning, protection from prolonged moisture), can last 5–8 years or beyond. Vitello box leather offers resistance of approximately 3–5 years under ordinary use conditions. A vulcanised rubber strap exhibits more predictable wear, with an operational life of 3–4 years before the texture begins to deteriorate. Longevity increases significantly by removing the watch during extreme activities and occasionally applying leather-specific nourishing creams.
