Strap for Longbridge Club Stainless Steel / Black

The lug width of the Reservoir Cars RSV01.LB/130-12s_BPL01 is 20 mm. This measurement is critical for aftermarket strap compatibility. You can verify it by measuring the distance between the inner attachment points of the lugs using a digital calliper, keeping the measurement perpendicular to the case. Reservoir specifies this dimension in the model's official technical documentation. A tolerance of ±0.5 mm is acceptable to ensure optimal fit without excessive play.

The most suitable strap depends on your intended use. For formal contexts, we recommend black or brown alligator with fine grain, which creates contrast with the brushed case and amplifies the automotive heritage. For an elegant alternative that develops natural patina, vegetable-tanned calf in burgundy or dark brown harmonises beautifully with the steel texture. NATO straps in grey-blue or black canvas are ideal for sporting and outdoor use, maintaining the minimalist appeal of the square case. FKM rubber is recommended for humid environments or high-wear situations, as it is waterproof and resistant to oils.

Strap replacement requires a specific tool: a spring bar tool. First, secure the case on a soft cloth to prevent scratches. Locate the access hole on the lug, insert the sharp tip of the spring bar tool to compress the internal spring, then extract the pin. Repeat on the other lug. You can now remove the old strap. To install the new strap, insert the pin into the first lug, compress it with the tool, and snap it into position. Verify that the pin is fully inserted and securely fixed before wearing the watch.

Any strap with a 20 mm lug width is theoretically compatible with the Reservoir Cars RSV01.LB/130-12s_BPL01. However, we recommend verifying the total length: the model has a compact case (39 mm) that requires balanced proportions. Straps in alligator, calf leather, exotic leather, NATO, technical rubber, and fabric are all compatible. Milano Straps offers a curated range of 20 mm straps specifically selected to match the automotive aesthetic of the Reservoir Cars, with customisation options available at Atelier Casati Milano.

Lifespan depends on material and intensity of use. A quality alligator or calf strap, worn daily, can last 2-4 years before requiring replacement or restoration. Primary wear occurs in the contact zone with the deployant buckle, where leather experiences repeated mechanical stress. The natural patina developed is desirable and fits the concept of a consciously aged tool. NATO fabric straps have superior longevity (5-7 years), whilst FKM rubber resists up to 8-10 years due to its synthetic nature. Regular maintenance (cleaning with a damp cloth, periodic conditioning) significantly extends strap life.
