Strap for Rendez-Vous Night & Day Bracelet

The lug width of the Jaeger-LeCoultre Rendez-Vous (reference 3468121) is 14mm. This specific measurement is determined by the octagonal case geometry of the 29mm case and represents a non-standard specification in the watch industry. To verify the measurement, place a ruler on the case and measure the distance between the two lugs perpendicularly; the value should correspond exactly to 14mm.

The choice of strap depends on your usage and personal style. For formal occasions and luxury material enthusiasts, high-quality alligator offers natural texture and exceptional durability (8-10 years). Vegetable-tanned calf leather is ideal if you wish the strap to develop natural patina over time. Rubber is the practical solution for humid environments, while NATO fabric offers maximum everyday versatility. At Casati Milano, you can personally select the material and colour at our Milan atelier.

To change the strap on your Rendez-Vous 3468121, you will need a specific tool to remove the spring bars (the small metal pins that secure the strap to the case). Position the screwdriver or dedicated tool under the spring bar and press downwards until the end protrudes, then extract it. Repeat the operation for the second lug. Insert the new strap by aligning the ends to the slots and reinsert the spring bars. If you lack experience, we recommend visiting a watchmaker or contacting Casati Milano directly.

Yes, at Milano Straps you will find a selection of artisanal straps specifically designed for the 14mm lug width. Our straps are crafted in alligator, calf leather, rubber, and NATO fabric, all available in various colours. Each strap is produced artisanally and can be personalised in terms of thickness, stitching, and finishing.

The lifespan of a leather strap depends on material quality and usage. High-quality alligator maintains shape and integrity for 8-10 years of daily wear. Vegetable-tanned calf leather has an average lifespan of 4-6 years, during which it develops beautiful natural patina. A rubber strap can last 5-7 years before showing signs of UV wear. Durability increases if the strap is not subjected to excessive humidity and if you periodically allow it to dry completely after use in humid climates.
