Strap for DolceVita 23 Quartz Stainless Steel / MOP

The Longines DolceVita L5.512.4.87.0 features a lug width of 17 millimetres. This specific measurement stems from the rectangular case proportions and the vertical geometry of its construction. To measure your lug width accurately, use a digital calliper positioned perpendicularly between the two case lugs, measuring from inner shoulder to inner shoulder. This precision is essential for selecting straps that fit perfectly to the case whilst maintaining the aesthetic harmony of the model.

For the DolceVita L5.512.4.87.0, alligator leather is the ideal material, its fine and regular texture harmonising perfectly with the case's clean proportions. Shell cordovan represents the most prestigious choice, developing a deep and unique patina over time. Calf leather, available in finishes ranging from smooth grain to structured texture, offers aesthetic versatility whilst maintaining elegance. The most suitable colours include cognac brown, deep black, dark blue, and intense bordeaux. Each material, chosen with appropriate vegetable tanning, amplifies the Art Déco identity of the model without compromise.

Strap replacement on the DolceVita L5.512.4.87.0 is accomplished by removing the spring bars (metal bars that secure the strap to the case). Use a dedicated tool or small plastic lever to gently lift the spring bars from their case slots. Once released, the old strap separates easily. The new strap, featuring the 17mm lug width, should be inserted into the lateral grooves of the case, ensuring the ends are properly positioned before reinserting the spring bars. If you wish to avoid the risk of scratching the case, consulting a professional watchmaker is always the safest choice.

A leather strap's lifespan depends upon the material selected, the vegetable tanning method applied, and daily wear patterns. A quality alligator strap, vegetable tanned, can last 5-8 years with proper care. Shell cordovan, owing to its natural structure, can exceed 10 years, developing characteristic patina over time. Calf leather, more delicate, averages 3-5 years of service. Regardless of material, longevity improves if you avoid prolonged sun exposure, water contact, and regularly clean the strap with leather-specific products. Milano Straps provides an 18-month warranty on all artisanal Casati Milano straps.
