Strap for Elegant Collection 25.5 Automatic Stainless Steel / Red Gold / Grey

The lug width of the Longines Elegant L4.309.5.72.7 is 16mm. This dimension is specific to the compact models in the Elegant collection and is essential for ensuring you order compatible straps. To verify your watch's lug width, use a digital calliper to measure the distance between the two lateral lugs on the case.

For the Longines L4.309.5.72.7, we recommend a black or dark brown alligator strap for a classic and elegant interpretation, or vegetable-tanned leather for a warmer, more vintage aesthetic. A shell cordovan strap represents the most durable and wear-resistant option. For sportier use, a NATO cotton strap maintains the compact elegance of the model.

To change the strap, you will need a spring bar tool and a flat work surface. Position the watch with the case stable, locate the small metal pins on the inner sides of the lugs, gently press inward with the tool until the lug is released, then remove the old strap. Insert the new 16mm strap by aligning the holes, then press the pin until it clicks into place. If unsure, consult an expert: Casati Milano offers this service via WhatsApp.

Yes, it is possible to use compatible aftermarket straps as long as they have exactly 16mm lug width. However, we recommend choosing verified quality straps: fine leathers such as alligator, vegetable-tanned calfskin and shell cordovan ensure longevity and superior tactile experience. On milanostraps.it you will find 16mm straps customisable and selected for compatibility and construction quality with this model.

A quality leather strap (alligator, calfskin, shell cordovan) worn daily has a lifespan of 3-5 years, depending on frequency of use and climatic conditions. Alligator straps tend to last longer thanks to the natural structure of the leather. Casati Milano offers straps with an 18-month warranty and the possibility of periodically renewing the strap with complete customisation.
