Strap for PRS 516 Quartz Chronograph Black

The lug width of the Tissot PRS 516 T044.417.21.051.00 is 20mm. This measurement corresponds to the internal distance between the two spring bar attachments on the case. To measure correctly, position a digital calliper between the inner edges of one lug and the other; the resulting value must be 20mm to ensure complete compatibility with aftermarket straps. Many specialist strap manufacturers maintain specific selections in their catalogues dedicated to this width, given the model's prevalence in the sports segment.

Strap choice depends on intended use and desired aesthetic context. For sporty-casual wear, we recommend a NATO strap in dark grey cotton or a vulcanised rubber model in black, both practical and durable. For those wishing to elevate elegance whilst maintaining technical character, an alligator tinted dark blue with vegetable tanning creates a pleasant dialogue with the case's satin finish. For daily urban use, a satin-finished calf leather in chocolate brown represents the ideal aesthetic compromise. All these materials are available in 20mm width from specialist suppliers.

The procedure is straightforward and requires no complex tools. Position the watch with the case back facing upwards, on a soft surface (cotton cloth). Locate the small holes on the lugs where the spring bars (elastic attachment pins) are inserted. Using a small plastic lever (spring bar tool) or the flat tip of a plastic card, gently press one spring bar downwards to release the old strap. Repeat on the other side. To fit the new strap, align the strap's holes with the spring bars and press until you hear a clicking sound. Verify that the strap is firmly secured by gently pulling. If you lack confidence, consult a specialist watchmaker or our Casati Milano Atelier for assistance.

Yes, provided the lug width is exactly 20mm and construction quality is controlled. Aftermarket straps produced by specialist manufacturers guarantee complete compatibility with reference T044.417.21.051.00, often offering superior materials and finishes compared to the factory strap. It is important to always verify technical specifications (lug width, thickness, attachment type) with the supplier. Straps purchased from milanostraps.it are tested and certified for compatibility with this measurement; furthermore, the Casati Milano Atelier provides personalised consultation to select the proposal best suited to your style and usage requirements.

The lifespan of a leather strap depends on tanning quality, usage intensity and maintenance. A satin-finished calf strap of good quality, used daily in urban settings, lasts an average of 3-5 years before showing signs of failure in the bending area adjacent to the lug. An alligator with vegetable tanning, thanks to superior structural density, can reach 5-8 years of useful life. Periodic maintenance (conditioning with natural oils every 6 months, protection from humidity and direct sunlight) significantly extends lifespan. Vulcanised rubber straps or cotton NATO straps, conversely, have longer lifespan (7-10 years) with minimal maintenance requirement, making them ideal for those preferring practicality and durability.
