Reverso 3363402— lug 20mm

The Jaeger-LeCoultre Reverso 3363402 is fitted with a 20mm lug width. This measurement is taken with a digital caliper positioned internally between the two lugs, at the contact point with the strap. It is the fundamental parameter for choosing a compatible strap without installation risks.

For a white gold reference with formal vocation like the Reverso 3363402, smooth and polished alligator leather in black or deep brown is the choice most consistent with the piece's identity. Polished Box-Calf calfskin represents a modern and composed alternative. Both enhance the Art Deco geometry of the case without competing with the refinement of the precious material.

The Reverso uses an attachment system integrated into the sliding lug, different from conventional springbars. Strap replacement should be performed with specific tools and, preferably, entrusted to a watchmaker or specialized atelier to avoid scratches on the white gold case. Casati Milano offers this service by appointment.

Yes, there are aftermarket straps with 20mm lug width compatible with the Reverso 3363402, available on milanostraps.it. It is important to verify that the strap ends are correctly shaped to fit the Reverso's attachment system and that the thickness of the lugs is adequate for the original slider.

A quality leather strap — alligator or vegetable-tanned calfskin — on a Reverso 3363402 can last from 2 to 5 years with regular use, depending on usage conditions and maintenance. Frequent exposure to sweat and humidity reduces leather lifespan; the Casati Milano warranty covers manufacturing defects for 18 months from purchase.
