Strap for Elegant Collection Automatic 29 Pink Gold / Diamond / MOP

The lug width of the Longines Elegant L4.287.9.87.0 is 14 millimetres. This narrow measurement is specific to the model and reflects the compact design and feminine proportions of the 29mm case. To verify compatibility, measure the internal space between the two lugs protruding from the case: it must be exactly 14mm. A strap with a different measurement will not be compatible and may damage the attachment mechanisms.

Alligator leather represents the most elegant choice for the Longines Elegant L4.287.9.87.0 in rose gold, thanks to its fine and uniform grain texture that does not visually compete with the precious metal. Alternatively, vegetable-tanned calf leather offers a pronounced texture and a patina that evolves over time, creating a fascinating dialogue with the gold. Shell cordovan, with its natural lustre and deep colour, is a bold choice for those seeking greater visual presence. Avoid sportive materials such as NATO or rubber, which would contradict the elegant DNA of the instrument.

To change the strap, a dedicated spring bar tool is required. Position the watch on a soft surface to prevent scratches. Using the spring bar tool, gently push the pin inward from one side until it disengages from its seat. Once the pin is free, remove the old strap. Repeat the procedure on the other side. Insert the new 14mm strap by aligning the lug holes with the two pins, then secure the pins into their seats. Ensure the strap is firmly anchored before wearing the watch.

Yes, the Longines Elegant L4.287.9.87.0 allows strap replacement with quality aftermarket options, provided the lug width is exactly 14 millimetres. We discourage low-quality generic straps: for a rose gold watch, it is preferable to choose noble leathers such as alligator, vegetable-tanned calf, or shell cordovan. Milano Straps offers a complete collection of 14mm-compatible straps, available both from catalogue and customisable through the Casati Milano atelier.

The lifespan of a leather strap depends on material, use and care. A high-quality alligator or calf strap, worn daily, has an average lifespan of 3–5 years before replacement is necessary. Shell cordovan, owing to its natural density, tends to last longer (5–7 years). Proper maintenance—avoiding prolonged exposure to water and heat, storing the watch in a dry location—significantly extends durability. Casati Milano provides an 18-month warranty on all custom straps, covering defects in workmanship and material.
