Strap for DolceVita 17.4 Quartz Stainless Steel / Diamond / Black

The lug width of the Longines DolceVita L5.258.0.57.0 is 13mm. This non-standard measurement reflects the elongated, tapered geometry of the case. To verify it accurately, use a digital calliper and measure the internal distance between the two attachment pins. Do not confuse this measurement with the total width of the strap at the wrist, which will be wider to ensure comfort. When ordering a custom strap, always communicate this lug width to the artisan workshop.

The ideal strap depends on your intended use and personal style. For formal and evening occasions, black alligator with cream thread stitching emphasises the Art Déco elegance of the piece. For daily wear, pull-up calf leather in cognac or brown tones offers comfort and develops a natural patina over time. Vegetable-tanned leather is excellent if you desire a strap that ages gracefully. For those preferring versatility, a natural black rubber strap maintains sophistication whilst reducing maintenance. Online available straps are already calibrated for the 13mm lug width and ready for fitting.

To change the strap, you require essential tools: a spring bar tool and the new strap with the correct 13mm lug width. Proceed as follows: place the watch on a soft surface; access the pins holding the strap; use the spring bar tool to slide the pin and release the old strap; repeat on the other side. Insert the pins into the new strap and secure them to the watch until they click into place. If you are unfamiliar with the process, Casati Milano atelier offers mounting service with consultation on material selection.

The lifespan of a leather strap depends on the material, usage and maintenance. A high-quality artisanal alligator or calf strap, with moderate daily use, maintains functionality and elegance for 3–5 years. Vegetable-tanned leather, if regularly treated with specific creams, can last 5–7 years whilst developing a rich patina. A natural rubber strap typically resists 2–3 years before visible wear appears. To extend durability, avoid prolonged exposure to direct sunlight and excessive humidity. Milano Straps offers reconditioning services and scheduled replacements, coordinated via WhatsApp with Casati Milano atelier.
