Strap for Rendez-Vous Night & Day Stainless Steel - Diamond / Silver / Alligator

The lug width of the Jaeger-LeCoultre Rendez-Vous 3448420 is 16mm. This non-standard measurement has been precisely calibrated to maintain perfect proportions between the 34mm case diameter and dial legibility. It is essential to measure accurately using a millimetre ruler inserted between the case lugs to avoid compatibility issues.

The best strap for the Rendez-Vous 3448420 is in dark brown alligator or superior-grade aniline calf leather. Alligator enhances the sobriety of the stainless-steel case with its natural lozenge-pattern grain, whilst aniline calf develops a patina over time, transforming the strap into a biographical object. The choice depends on context: alligator for formal wear, calf for versatility.

To change the Rendez-Vous 3448420 strap, remove the spring bars connecting the strap to the case using a dedicated spring bar tool. Position the tool beneath the bar, gently press to release the internal spring, and extract the pin. Repeat on both sides. Insert the new spring bars into the aftermarket strap and secure them to the case. This operation requires care to avoid damaging the case.

Any strap with a 16mm lug width is compatible with the Rendez-Vous 3448420, provided the width is measured with precision. Milano Straps offers a comprehensive selection of 16mm straps in alligator, calf, NATO cordura, and vulcanised rubber, all handcrafted from superior materials. Always verify the exact measurement before purchase.

The lifespan of a leather strap depends on frequency of use, leather type, and climate conditions. A superior-grade alligator strap, such as those by Casati Milano, typically lasts 5–7 years with moderate daily wear. Aniline calf patinas more rapidly, offering approximately 4–5 years before replacement becomes necessary. Proper maintenance—avoiding prolonged water exposure and direct UV—significantly extends strap life.
