Strap for PRS 516 Powermatic 80 Stainless Steel / Blue / Calf

The lug width (ansa width) of the Tissot PRS 516 T100.430.16.041.00 is precisely 20 mm. This measurement is taken from the lateral attachment slot of the case, i.e. the distance between the two spring bars that support the strap. This dimension is critical to ensure any aftermarket strap fits correctly without play or excessive tension.

There is no single 'best' option, but three excellent choices depending on intended use. For sporty elegance, we recommend alligator leather in vegetable tanning, in cognac or chocolate brown tones. For racing practicality, consider NATO in heavy canvas or FKM rubber, which ensures grip and quick-change capability. Shell cordovan represents the middle ground: conscious luxury with natural colour evolution over time. Your choice should reflect your primary use case.

The process is straightforward. Turn the watch face-down and position the lugs upward. Locate the spring bars that pass through the lateral slots in the case (visible when viewing the cross-section). Using a dedicated tool (spring bar tool) or small flat instrument, apply gentle downward pressure on the bar until the internal spring compresses. The strap will then release. Reverse the procedure to install your new 20 mm strap, ensuring both bars are fully seated in their slots.

Absolutely. Any strap with certified 20 mm lug width is compatible. Artisanal straps offer significant advantages over the original bracelet: aesthetic customisation, often superior construction quality, opportunity for seasonal rotation, and natural patina development for organic materials. Always verify that your strap comes from reputable makers who certify correct lug width compliance.

Durability depends on leather quality, tanning method, and usage patterns. High-quality alligator or cordovan in vegetable tanning lasts 5-7 years under moderate-to-heavy use with periodic maintenance (gentle cleaning, annual conditioning). Leather wears first at the extremities (where buckle or deployante attach) before structural failure occurs. If used daily in humid environments or with strong UV exposure, the strap loses elasticity after 3-4 years. FKM rubber offers superior longevity (8-10 years) because it does not age naturally like leather does.
