Reverso 2542540— lug 20mm

The Jaeger-LeCoultre Reverso 2542540 is fitted with a 20 mm lug width. Despite the case measuring 24.40 mm in width, the rectangular geometry of the Reverso Classic Small line requires a 20 mm strap to ensure correct proportions and compatibility with the flip case mechanism.

For the Reverso 2542540 in steel, smooth box-calf leather or alligator crocodile represent the most coherent choices with the Art Deco aesthetic of the case. It is essential to select a strap with a lug thickness not exceeding 3.5 mm to respect the flip case mechanism. At milanostraps.it you will find a selection of compatible 20mm straps crafted artisanally.

Strap changes on the Reverso 2542540 are made via the classic spring bars positioned in the lugs of the sliding case frame. It is advisable to use a dedicated spring bar tool with a fine tip to avoid scratching the satin-finished surfaces of the case. Given the delicacy of the flip mechanism, it is recommended to consult a watchmaker or the Casati Milano atelier for the first strap changes.

Yes, any standard 20 mm strap with contained thickness is compatible with the Reverso 2542540, provided it respects the maximum lug thickness of approximately 3.5 mm imposed by the flip case. Milano Straps artisanal straps in 20mm size are selected to guarantee this compatibility, with options in alligator, calf leather, and NATO nylon.

The lifespan of a leather strap depends on the quality of the leather, frequency of use, and maintenance. A quality artisanal box-calf or alligator strap, kept away from excessive water and perspiration and occasionally treated with nourishing cream, can last between 2 to 5 years. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
