Strap for DolceVita 16 Quartz Two Tone Diamond

The lug width of the Longines DolceVita L5.158.5.09.7 is precisely 12mm. This technical specification is determined by the proportion of the ultra-thin 16mm diameter case. It is essential to measure the distance between the two strap attachment holes on the case before purchasing an aftermarket strap, as standard 14mm or 16mm straps would be incompatible.

For the DolceVita, straps in alligator or vegetable-tanned calf leather are recommended, as their fine texture and patina development preserve the aesthetic sobriety of the model. Alligator in particular, with its regular grain, creates visual continuity with the mother-of-pearl dial. Avoid NATO fabric straps or vibrant colours such as red and blue, which would compromise the formal character of the watch.

To change the strap, you need a strap remover tool or a small flathead screwdriver. Insert the tool into the small lateral hole of the spring bar beneath the lug, compress the internal spring slightly and slide the lug out of the attachment hole. Repeat for the other lug. When installing the new strap, verify that the spring bar is correctly positioned at the ends. If you prefer to avoid the risk, Casati Milano offers strap change services.

Yes, provided the lug width is exactly 12mm. Milano Straps offers a specialised collection of 12mm straps calibrated to this specification. Before purchasing, measure the distance between the two attachment holes on the case to ensure compatibility, as even minor variations would compromise the fit.

The lifespan of a leather strap depends on the material, use and maintenance. An alligator strap with vegetable tanning, if properly cared for (protection from excessive moisture, regular drying, occasional neutral balm treatments), can last 8-12 years. Shell cordovan, due to its density, reaches 15+ years. Calf leather, being more delicate, has an average lifespan of 5-8 years. Straps crafted by Casati Milano benefit from an 18-month warranty against manufacturing defects and abnormal wear.
