Frequently asked questions

What is the lug width of the Jaeger-LeCoultre Reverso Q2588120?

The lug width of the Jaeger-LeCoultre Reverso Q2588120 is precisely 18 mm. This dimension is specific to the Classic format and is critical when selecting a strap: the pin securing the strap to the case must align perfectly with this width. It is not possible to use straps of different widths without case modification, which is why accuracy in selection is essential.

What is the best strap for the Jaeger-LeCoultre Reverso Q2588120?

The ideal strap depends on intended use and aesthetic preference. For classical elegance, cognac brown alligator or vegetable-tanned calf represent the most coherent choices with the Reverso's Art Deco spirit. Those seeking a patina that evolves over time will find shell cordovan represents the pinnacle, though it demands greater maintenance. A perforated calf with deployante clasp is recommended if you desire versatility between formal and casual contexts.

How do I change the strap on my Jaeger-LeCoultre Reverso Q2588120?

Strap changes require basic tools: a strap tool or small screwdriver. Position the watch on a stable surface, locate the lateral pins securing the strap to the case, and use the tool to gently compress and extract them. Insert the new pins into the fresh strap and reinsert them into the case until they click into place. This operation requires patience and precision rather than force.

Can I use an aftermarket strap compatible with the Jaeger-LeCoultre Reverso Q2588120?

Yes, provided the lug width is exactly 18 mm and the construction quality aligns with the watch's value and heritage. An artisanal quality strap in alligator or vegetable-tanned calf preserves the character of the Q2588120 and allows personalisation rarely found in original accessories. Your warranty is not compromised by strap changes, as this operation is reversible and standard practice.

How long does a leather strap last on the Jaeger-LeCoultre Reverso Q2588120?

The lifespan of an artisanal strap depends on leather quality, intensity of use, and maintenance practices. A superior quality alligator or calf strap may last 3-5 years with daily wear, or longer with periodic care (gentle cleaning with damp cloth, conditioning with specialist balms). Shell cordovan, if properly maintained, can last 7-10 years. The 18-month warranty on manufacturing defects covers construction flaws, not natural wear.
