Strap for DolceVita 23 Quartz Stainless Steel / MOP

The lug width of the Longines DolceVita L5.512.4.87.3 is 17mm, a specific measurement that excludes standard off-the-shelf straps. This dimension is calculated by measuring the distance between the two spring bar attachments on the case. It is a rare width in the luxury watchmaking landscape, requiring bespoke strap construction to ensure perfect fit and zero play.

For the DolceVita L5.512.4.87.3, we recommend alligator with fine grain—the regular grain naturally complements the squared lines of the case. Alternatively, vegetable-tanned calf offers natural ageing and progressive patina development. For summer or casual applications, organic cotton NATO or quality rubber maintain proportions without overwhelming this minimalist design.

To change the strap, you will need specific tools: a spring bar tool and a small press. Position the watch on a stable surface, gently insert the tip of the spring bar tool into the lateral hole of the lug, compress the elastic pin, and extract the bar. Repeat on the other side. Install the new strap by reversing the procedure. For specific measurements such as 17mm, we recommend consulting a professional to avoid damage to the case.

Compatible straps must feature exactly 17mm lug width. On milanostraps.it you will find complete collections of artisanal straps in this size, crafted in alligator, vegetable-tanned calf, NATO, and rubber. All are customisable in length, initials, and stitching thread. The Casati Milano atelier also offers fully bespoke creations with direct consultation.

The lifespan of a leather strap depends on usage, care, and leather quality. Premium alligator or calf, worn regularly but rotated with other straps, can last 3-5 years or longer. Vegetable-tanned leather ages exceptionally well, developing natural patina. Minor creasing and progressive thinning are characteristic of fine leather and desirable. Keeping the strap dry, avoiding prolonged moisture exposure, and protecting from extreme heat significantly extends longevity.
