Strap for Longbridge Royal Blue Stainless Steel / Black

The lug width of the Reservoir Cars RSV01.LB/130-13s is 20 millimetres. This specification is determined by the geometry of the 39mm case and represents the standard construction for all compatible straps. To verify it, use a digital calliper to measure the internal space between the spring bars.

The ideal strap depends on your intended use. For pure elegance, we recommend alligator with vegetable tanning in natural grey or cognac brown. For versatility, a superior quality calf leather in neutral tones. For practicality, a grey dark NATO fabric strap maintains aesthetic balance without compromise. All straps must respect the 20mm lug width.

Strap replacement is a straightforward operation. Use a spring bar tool or small chisel to gently lift the lateral elastic pins. Extract the old strap by applying outward pressure. Insert the new strap by aligning the holes with the lugs and press until it clicks into place. Verify that the pin engages fully. If the strap has a deployant clasp, ensure it is installed symmetrically on the case.

Yes, the Reservoir Cars RSV01.LB/130-13s is fully compatible with certified quality aftermarket straps, provided they respect the 20-millimetre lug width specification. We advise against generic products: a handcrafted strap in alligator or calf leather guarantees durability and aesthetic coherence with the watch's constructive seriousness. Always verify dimensions before ordering.

A quality leather strap (vegetable-tanned alligator or excellent calf) typically resists 3–5 years of daily wear, varying according to usage frequency and environmental exposure. Leather develops natural patina that increases its character. Periodic maintenance—gentle cleaning and conditioning with specific creams—significantly extends its lifespan. A technical fabric NATO strap offers superior durability, lasting up to 7–10 years of regular use.
