The Heritage

The Reverso was introduced in 1931 as a watch with a reversible case to protect the dial during polo matches. It is powered by the Jaeger-LeCoultre manual-winding Caliber 657 with hour and minute indications. The rectangular case features the characteristic rotating mechanism that allows the dial to be completely flipped over.

FAQ

What is the lug width of the Jaeger-LeCoultre Reverso 2618540?

The Jaeger-LeCoultre Reverso 2618540 is fitted with a 20 mm lug width. To verify this precisely, measure with a digital caliper the internal distance between the two lugs at the strap attachment point.

What is the best strap for the Jaeger-LeCoultre Reverso 2618540?

For the Reverso 2618540, a flat-worked alligator porosus or smooth calf leather strap with tight grain is the most appropriate choice for the Art Déco aesthetic of the case. It is essential that the attachment end has limited thickness, compatible with the low profile of the Reverso. You will find a selection of handcrafted options on milanostraps.it in the 20mm strap section.

How do you change the strap on a Jaeger-LeCoultre Reverso 2618540?

Changing the strap on the Reverso requires a fine-tipped spring bar tool to remove the spring bars between the lugs. Given the rectangular geometry of the case and the limited space between lug and chassis, it is advisable to proceed with caution to avoid scratching the brushed finishes. If in doubt, a watchmaker or the Casati Milano atelier can perform the installation on-site.

Are there aftermarket straps compatible with the Jaeger-LeCoultre Reverso 2618540?

Yes, the Reverso 2618540 accepts aftermarket straps with 20 mm attachment, provided that the thickness of the end is suitable for the case lug. Milanostraps.it offers a selection of handcrafted 20mm straps compatible with the watch, also made to measure through the Casati Milano bespoke service.

How long does a leather strap last on a Jaeger-LeCoultre Reverso?

The lifespan of a leather strap depends on the quality of the leather, frequency of use, and exposure to sweat and humidity. A high-quality alligator or calf leather strap with vegetable tanning can last from 2 to 5 years with regular maintenance. Casati Milano offers an 18-month warranty against manufacturing defects on all handcrafted straps.
