Strap for Reverso Classic Medium Duetto Pink Gold Bracelet

The lug width of the Jaeger-LeCoultre Reverso 2572120 is exactly 18 millimetres. This dimension corresponds to the geometric proportions of the 24.40 mm case and ensures perfect visual balance on the wrist. To verify this, measure internally between the two case lugs: the available space will be precisely 18 mm. A strap of this measurement is essential to guarantee both the aesthetics and functionality of the reversible case.

The best strap for the Reverso 2572120 depends on your usage and personal preferences. Alligator represents the most classic choice: the natural texture of the scales creates a magnificent dialogue with the Art Deco geometry of the case. For absolute elegance, choose dark brown or cognac alligator, which pairs perfectly with the pink gold. Alternatively, smooth calf leather offers sobriety and tradition, whilst vegetable-tanned leather develops a patina that mirrors the ageing of the gold. For daily wear, rubber offers durability without aesthetic compromise.

Changing the strap on the Reverso 2572120 requires care given the particularity of the reversible case. Use a dedicated tool (spring bar tool) to gently remove the lugs from the old strap, inserting the blade into the thin slot beneath the lug. Then position the new strap, aligning it with the lug holes, and reinsert the lugs using the same tool, ensuring they are fully seated. If you are not experienced, entrust the task to a professional: the reversibility of the case requires precision in assembly.

Yes, any high-quality aftermarket strap with an 18 mm lug width is compatible with the Reverso 2572120. The important factor is that the thickness and flexibility do not interfere with the case's rotation mechanisms. Choose artisanal brands that understand the specifics of the Reverso: premium leather (alligator, calf, vegetable-tanned) and precise stitching. Straps purpose-made for 18 mm lug widths guarantee perfect fit and preserve the original design integrity.

The lifespan of a leather strap depends on material quality, frequency of wear, and care. A high-quality artisanal alligator or calf strap, worn daily, can last 3–5 years before showing significant wear. Vegetable-tanned leather, if properly maintained and kept dry, may last considerably longer while developing a fascinating patina. A rubber strap is more durable (5–7 years) and resists moisture better. The 18-month warranty on manufacturing defects provides initial protection, whilst longevity will also depend on how you store and use the strap.
