Strap for Reverso One Duetto Stainless Steel / Silver / Alligator

The Jaeger-LeCoultre Reverso 3348420 has a lug width of 14mm. This dimension is essential for correctly matching a strap to the watch: any strap intended for this model must respect this exact measurement to maintain the aesthetic proportions of the case and ensure a harmonious transition between steel and leather.

For the Reverso 3348420, we primarily recommend an alligator strap, which accentuates the rigorous Art Déco geometry of the case. Natural alligator, with its regular columnar texture, amplifies the proportional order of the design. Alternatively, vegetable-tanned calf leather offers a patina that evolves over time, whilst shell cordovan provides natural smoothness without artificial treatments.

Strap replacement on a 3348420 occurs through the case lugs, which incorporate a specific release system for the Reverso. We recommend consulting an experienced watchmaker or the Casati Milano service, which guarantees correct technical strap change without damaging the case. The procedure requires specialised tools and precise knowledge of the lug attachment mechanism.

Yes, any high-quality strap with 14mm lug width is technically compatible with the 3348420, provided it is crafted from noble materials and artisanal construction. Milano Straps offers a curated selection of 14mm straps that respect the aesthetic and qualitative standards of the Reverso, available both as ready-made options and customisations through Casati Milano.

The lifespan of a leather strap depends on frequency of use, climate, and tanning quality. A vegetable-tanned leather strap, such as those from Milano Straps, can last 4-7 years with regular use, developing a personal patina over time. The Casati Milano warranty covers 18 months against manufacturing defects; natural wear and leather ageing fall within the normal evolution of the material.
