Frequently asked questions

What is the lug width of the Longines DolceVita L5.512.5.87.7?

The lug width of the DolceVita L5.512.5.87.7 is 17 mm. This measurement represents the distance between the two lateral attachment points of the case and is critical to ensure that the strap is compatible with the terminal lugs. Incorrect measurement—confusing 17 mm with 16 mm or 18 mm—results in misalignment and premature wear of the lug slots.

Which strap is recommended for the Longines DolceVita L5.512.5.87.7?

Mississippi alligator leather is the primary choice: its coarse grain and articulated texture harmonise exceptionally well with the two-tone case and mother-of-pearl dial. French Taurillon calf leather with vegetable tanning is a versatile alternative, whilst shell cordovan offers natural lustre and develops patina over time. Avoid NATO fabric and synthetic rubber straps, which are anachronistic relative to the elegance of the L176 movement.

How do I change the strap on the Longines DolceVita L5.512.5.87.7?

The DolceVita L5.512.5.87.7 features fixed lugs, not pivoting spring bars. To change the strap, use a spring bar tool to gently extract the attachment pins. Position the watch on a soft cloth and operate with slow, controlled movements. If unfamiliar with the procedure, consult a professional watchmaker to avoid damage to the case.

Are aftermarket straps compatible with this model?

Yes. Aftermarket straps with 17 mm lug width are fully compatible with the L5.512.5.87.7. Milano Straps supplies artisanal leather straps (alligator, calf, shell cordovan) customisable in length, stitching thread and initials. All 17 mm straps in the catalogue guarantee mechanical compatibility and precise constructive tolerances.

What is the lifespan of a leather strap for this Longines?

An alligator or vegetable-tanned calf strap, if properly maintained (kept dry, protected from direct heat sources), has a lifespan of 3–5 years with daily wear, extending to 8–10 years with occasional use. Shell cordovan, owing to higher fibre density, extends lifespan to 5–7 years under normal conditions. Natural patina develops and ageing imparts character to the strap; this is not deterioration but rather maturation.
