The Reverso 2438522, seen from the bench

The Jaeger-LeCoultre Reverso 2438522 (also known as Q2438522) embodies the iconic flip case design patented in 1931, featuring a rectangular stainless steel case measuring 25.50 mm. The Medium Lady model displays hours, minutes and small seconds via the in-house caliber JLC 822/2 manual movement. The strap width is precisely 16 mm, specific to Lady variants and distinct from the 18 mm or 20 mm sizes of other Reverso family members.

Frequently asked questions

What is the lug width of the Jaeger-LeCoultre Reverso 2438522 (Q2438522)?

The Jaeger-LeCoultre Reverso 2438522, also known as Q2438522, features 16 mm lugs. This is the internal width between the two horizontal lugs measured close to the case: always verify it with a digital caliper before purchasing a compatible strap.

What is the best strap for the Jaeger-LeCoultre Reverso Q2438522?

For the Art Déco geometry of the Reverso 2438522, the most suitable straps are smooth calf leather with compact grain or lacquered Mississippiensis alligator. Both respect the formal rigidity of the rectangular case without contrasting its lines. Hand-braided leather is the right choice for more informal occasions.

How do you change the strap on the Jaeger-LeCoultre Reverso 2438522?

The Reverso 2438522 strap is replaced using a dedicated lever tool or a very thin flat-head screwdriver. The Reverso's lugs, given their rectangular architecture, require spring bars with length calibrated for the 16 mm spacing. It is recommended to entrust the task to a watchmaker or specialized atelier to avoid scratches on the stainless steel case.

Are there aftermarket straps compatible with the Jaeger-LeCoultre Reverso Q2438522?

Yes. On milanostraps.it you will find a selection of 16 mm aftermarket straps compatible with the Reverso 2438522 (Q2438522), handcrafted in calf leather, alligator, and other materials. Each strap is finished with buckles and keepers that can be coordinated with the steel of the original case.

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

A quality leather strap — calf or alligator with vegetable tanning — on a Reverso lasts on average between 18 and 36 months with daily use, depending on exposure to sweat, humidity, and heat. Regular maintenance with colorless nourishing cream and rotation with a second strap significantly extend the life of the leather. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
