Strap for DolceVita 20 Quartz Stainless Steel Diamond

The lug width of the Longines DolceVita L5.155.0.16.2 is precisely 15 millimetres. This measurement is crucial for selecting a compatible aftermarket strap and is determined by the distance between the metal lugs of the rectangular case. Accurate measurement is essential before ordering, as straps of different sizes (14mm or 16mm) will not fit properly, compromising the aesthetic balance of the timepiece.

For the DolceVita, a strap in alligator, vegetable-tanned calf leather, or quality rubber is recommended, always in the 15mm width. Alligator creates an elegant contrast with the stainless steel case and develops a natural patina over time. Vegetable-tanned calf leather offers greater versatility and character, evolving with use. NATO straps in subtle colours (black, navy blue) represent a sporty alternative without compromising the Art Deco minimalist design.

Strap replacement requires a specific tool (spring bar tool or pin remover). Position the watch on a soft pad to avoid scratches. Using the spring bar tool, gently push it under the pin of the lug until the pin emerges from its seat. Repeat on the other side. Insert the new 15mm strap into the lugs and reinsert the pins with the same gentleness. If you lack experience, consult a professional watchmaker to avoid damaging the case.

Yes, numerous 15mm aftermarket straps are available from specialised suppliers. Milano Straps offers a comprehensive collection of artisanal straps in various leathers and finishes, all customisable in width, initials, and stitching thread choice. The Casati Milano atelier also creates bespoke made-to-measure straps, with direct consultation on leather selection and 18-month warranty, ensuring perfect compatibility with your specific personalisation requirements.

The lifespan of a leather strap depends on the quality of the tanning and usage. An artisanal-quality vegetable-tanned calf strap typically lasts between 3 and 5 years with moderate daily wear (4–5 days per week). Alligator, thanks to its more robust fibrous structure, can last 5–7 years. Maintenance is crucial: avoid prolonged exposure to water, extreme humidity, and direct UV rays. A best practice is to rotate straps, allowing each to dry completely between wearings, significantly extending their lifespan.
