Strap for Rendez-Vous Night & Day Medium Stainless Steel / Blue / Alligator

The Jaeger-LeCoultre Rendez-Vous 3448480 features a lug width of 16 millimetres. This measurement represents the horizontal distance between the spring bar pins on the case lugs and is the fundamental parameter for identifying compatible straps. Measuring precisely with a digital calliper is essential to avoid lateral instability during wear.

The ideal material depends on intended use and aesthetic preference. Alligator leather delivers formal sophistication and evolving patina; vegetable-tanned calf offers natural warmth and character development over time; shell cordovan ensures superior durability and natural lustre. The choice must respect the delicate proportions of the 34-millimetre case and harmonise with the diamond-set crown's elegance.

The strap is changed by removing the lateral spring bar pins from the case lugs. With the watch clean and placed on a flat surface, use a dedicated tool — available from specialists or Casati Milano — to compress the pin slightly and extract it. Insert the new strap by securing the pins into the corresponding seats until they lock firmly. If uncertain, consult a specialised atelier.

All straps with a 16-millimetre lug width are compatible with the Rendez-Vous 3448480. Milano Straps offers a curated selection of artisanal 16mm straps, crafted from superior materials: alligator, vegetable-tanned calf, shell cordovan, and technical rubber. Each piece is selected to maintain the original case's aesthetic proportions.

An artisanal leather strap, crafted with vegetable tanning or shell cordovan, can last 5–10 years with regular maintenance: gentle cleaning with a damp cloth, immediate drying, avoiding prolonged water exposure. Alligator and vegetable-tanned calf develop a natural patina that improves with time. Casati Milano's 18-month warranty covers manufacturing defects, whilst natural wear represents the strap's aesthetic evolution.
