Frequently asked questions

What is the lug width of the Longines DolceVita L5.255.4.87.0?

The lug width of the Longines DolceVita L5.255.4.87.0 is 15mm. This non-standard measurement reflects the elegant and compact proportions of the rectangular case—a deliberate design choice that preserves the visual balance of the original Art Déco aesthetic. Correct measurement is taken from the internal point of one lug to the other.

What strap material is recommended for the Longines DolceVita L5.255.4.87.0?

For the DolceVita L5.255.4.87.0, premium alligator in cognac or deep brown tones is highly recommended: its natural texture enhances the geometric purity of the case without competing visually. An excellent alternative is vegetable-tanned calf leather, which creates a minimalist aesthetic. For a timepiece with temporal evolution, Japanese shell cordovan develops a fascinating patina that transforms the watch over time.

How do you change the strap on a Longines DolceVita L5.255.4.87.0?

The Longines DolceVita L5.255.4.87.0 uses a standard lug system: employ a spring bar tool to extract the two metal lugs holding the strap. Position the tool beneath the suspension bar until you feel the release click, repeat on the other side, and replace the strap. If unfamiliar with this procedure, a specialist can perform the change with care.

Is there an aftermarket strap compatible with the DolceVita L5.255.4.87.0?

Yes, on milanostraps.it you will find artisanal 15mm straps compatible with this reference, crafted with selected leathers and available in various finishes. They are customizable in sizing, initials, and stitching thread colour. For a bespoke experience, the Casati Milano atelier creates made-to-measure straps specifically for your DolceVita, with personal consultation and 18-month warranty.

How long does a natural leather strap last on a Longines DolceVita L5.255.4.87.0?

The lifespan of a natural leather strap depends on usage intensity and tanning quality. A first-rate alligator or shell cordovan offers 3–5 years of daily wear; vegetable-tanned calf reaches 2–4 years. Replacement frequency is inversely proportional to the number of watches you own: alternating timepieces reduces wear per strap. The Casati Milano atelier guarantees 18 months on its own craftsmanship.
