Strap for Rendez-Vous Jewellery Shooting Star Pink Gold - Diamond / Atelier des Métiers Rares / Bracelet

The Jaeger-LeCoultre Rendez-Vous Q36423C3 features a lug width of 17 millimetres. This undersized dimension, compared to contemporary sports models, is perfectly consistent with the elegant dress watch identity of the model. To measure the lug width accurately, calculate the distance from the inside of the right lug to the inside of the left lug, passing directly over the dial. A compatible strap must respect this measurement with precision: even half a millimetre deviation generates negative visual effects.

For a Jaeger-LeCoultre Rendez-Vous in rose gold, alligator remains the most natural choice: the tapered texture of the grain, the depth of patina over time, and its ability to absorb the prestige of rose gold create a rare aesthetic alliance. Warm brown tones—cognac, chocolate, medium brown—ensure chromatic harmony. Vegetable-tanned calf represents a conscious alternative, with a smooth texture that evolves over time. Shell cordovan in chestnut or burgundy offers visual solidity and increasingly rich patina over the decade.

Changing the strap on the Rendez-Vous Q36423C3 is accomplished via Spring Bars: small metal rods positioned internally within the lug attachments of the case. Using a specific Spring Bar Tool, gently compress the internal spring and extract the bar, allowing the removal of the old strap and insertion of the new one. The operation requires precision and a steady hand: if unfamiliar with the procedure, it is advisable to entrust the task to a professional. Casati Milano offers this service during custom strap personalisation.

Yes, it is entirely possible to use a high-quality aftermarket strap on a Jaeger-LeCoultre Rendez-Vous Q36423C3, provided it respects the 17-millimetre lug width and is constructed to elevated standards. An artisanal leather strap, crafted using sartorial techniques, is not only compatible but allows complete personalisation of the watch's aesthetic identity. Milano Straps offers a curated collection of 17mm straps specifically selected for dress watch models of this calibre.

The lifespan of a leather strap depends on the material type and frequency of wear. A high-quality artisanal alligator strap lasts an average of 4–6 years with daily use, thanks to its particularly resistant fibrous structure. Vegetable-tanned calf has a similar duration, but the leather tends to evolve aesthetically, generating increasingly rich patina. Shell cordovan is the longest-lasting choice: with proper care, it easily surpasses a decade of use, developing a profound and characteristic patina. The warranty on manufacturing defects is 18 months through Casati Milano.
