Reverso 2518140— lug 20mm

The Jaeger-LeCoultre Reverso 2518140 is fitted with a 20mm lug width. This measurement is determined by the proportions of the rectangular 24.40mm case and can be verified using a millimeter caliper positioned between the two lugs.

For the steel Reverso 2518140, a black or tobacco brown smooth calfskin strap with pin buckle is the most coherent choice with the Art Deco aesthetic. Mississippiensis alligator with a brick pattern represents a more refined option, capable of complementing the case's fluted bezel visually. For less formal contexts, a two-tone nylon NATO or thin rubber are functional alternatives.

The Reverso 2518140 strap is replaced using a fine-tipped spring bar tool, applying leverage to the bayonet spring that secures the strap to the case lugs. The operation requires care to avoid scratching the steel case: it is advisable to place it on a soft cloth and use a dedicated tool. If uncertain, it is best to consult a watchmaker or Casati Milano's atelier.

Yes. All straps with 20mm attachment are technically compatible with the Jaeger-LeCoultre Reverso 2518140. milanostraps.it offers a selection of 20mm straps in leather, alligator, NATO, and rubber designed for watches in this category, with finished edges and calibrated thicknesses to preserve the proportions of the Reverso case.

The lifespan of a leather strap depends on the quality of the leather, frequency of use, and exposure conditions. Premium calfskin or artisanally-worked alligator, if kept away from excessive water and perspiration, maintains structural and aesthetic integrity for 2-4 years of regular use. Casati Milano offers an 18-month warranty against manufacturing defects on all custom-made straps.
