Strap for DolceVita 17.7 Quartz Pink Gold - Diamond / MOP

The lug width of the Longines DolceVita L5.258.9.87.0 is 13mm. This measurement is specific to the DolceVita line and represents the distance between the two lugs (the pins on the case) that hold the strap. Any aftermarket strap must respect this specification, as different lug widths would cause mechanical play or structural incompatibility with the case.

Alligator is the premier choice for this pink gold model: the alligator's natural geometric grain complements the rectangular lines of the case perfectly, and the leather ages beautifully in harmony with pink gold. Vegetable-tanned calf leather is a noble alternative, ideal in cognac or burgundy tones for those seeking chromatic contrast. NATO fabric remains a practical option for daily versatility and durability.

To change the strap, use a spring bar tool to remove the spring bars from the case: insert the tool into the small groove beneath the lug, compress the internal spring, and extract the pin. Align the new strap with both lug holes and reinsert the spring bars until they click into position. We recommend consulting a watchmaker if you lack experience, to prevent damage to the bars or case.

Yes, the original strap can be replaced with an aftermarket strap compatible with 13mm lugs. It is essential to verify that the new strap is made from quality materials (alligator, vegetable-tanned calf, shell cordovan, FKM rubber) and that the spring bars are suitable. Milano Straps offers a complete collection of bespoke 13mm straps customisable in length, material, and stitching thread.

The lifespan of a leather strap depends on intensity of use, climate conditions, and material quality. Premium alligator or vegetable-tanned calf, if properly maintained (avoiding excessive moisture and prolonged UV exposure), typically lasts 5–7 years in daily wear. FKM rubber maintains structural performance for 3–4 years. Atelier Casati Milano guarantees 18 months on construction quality and stitching, regardless of natural leather wear.
