Strap for DolceVita 17.4 Quartz Stainless Steel / Diamond / MOP

The lug width of the Longines DolceVita L5.258.0.87.5 is 13 mm, measured centre-to-centre between the two straight lugs on the rectangular case. This dimension is not an industrial standard, making it essential to select straps specifically dimensioned to avoid excessive play or forced adjustments.

Alligator represents the most coherent choice with the DolceVita's Art Déco language, thanks to its fine grain and regular spine pattern. Alternatively, calf leather offers superior chromatic versatility, whilst vegetable tanning represents an ecological option that develops a fascinating patina over time. Avoid canvas or heavily structured fabric straps, which contrast with the watch's formal elegance.

Remove the old strap using a spring bar removal tool (the small metal levers that secure the strap to the lugs). Position yourself at a stable table with good lighting. Gently press the spring bar towards the case centre whilst extracting the strap. Insert the new strap, aligning it correctly before releasing the spring bar, verifying that it is securely engaged.

Yes, it is compatible with any high-quality strap fitted with 13 mm lug width. However, selecting a bespoke strap crafted by specialised ateliers such as Casati Milano ensures optimal proportions, impeccable finishing, and long-term warranty. Mass-market straps with 13 mm width are rare and often of inferior quality.

Durability depends on material and usage. High-quality alligator or calf leather, worn daily, typically lasts 3–5 years before replacement becomes necessary. Vegetable-tanned leather ages more rapidly in appearance but remains robust. A bespoke strap from Casati Milano carries an 18-month warranty and can be restored or repaired at the atelier itself to extend its service life.
