Jaeger-LeCoultre
Rendez-Vous 3433490— lug 18mm

The Jaeger-LeCoultre Rendez-Vous 3433490 is fitted with an 18 mm lug width. To verify this, measure with a digital caliper the space between the two lugs of the case at the narrowest point: the correct value is exactly 18 mm, which is necessary to ensure precise strap mounting without play.

For a 18-karat white gold case, a polished alligator strap—preferably in hornback scale with regular grain—represents the most coherent aesthetic choice. Alternatively, smooth calf leather in neutral tones such as écru, cream, or pearl gray ensures refined pairing for daily wear. Casati Milano creates both types custom-made in their Milan atelier.

The strap is removed using a flat-tipped spring bar tool or dedicated instrument that slides the spring bar between the case lugs. On a white gold case, it is essential to protect the surfaces with a soft cloth or rubber pads to prevent scratches. If you lack experience, it is advisable to consult a watchmaker or the Casati Milano atelier, where the change is performed with professional tools without risk to the case.

Yes. All straps with an 18 mm lug width and standard spring bar are technically compatible with the Rendez-Vous 3433490. Milano Straps offers a wide selection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-18mm">18mm</a> artisanal straps in leather, alligator, and fabric, produced with materials and finishes appropriate to the standard of a haute horlogerie timepiece.

Durability depends on material and use: a quality alligator strap, with proper care (kept away from direct moisture and prolonged sweat), maintains structural integrity and elegant patina for 3-5 years. Smooth calf leather has an average lifespan of 2-3 years with daily wear. Casati Milano offers an 18-month warranty against manufacturing defects on all straps made in their atelier.
