The DolceVita L5.155.4.83.6 (aka: L51554836), seen from the bench

The Longines DolceVita L5.155.4.83.6 is a rectangular watch featuring the L178 automatic movement with hours, minutes, and small seconds.

This model draws from 1920s–1930s Art Déco aesthetics while preserving contemporary Swiss precision and reliability.

Frequently asked questions

What is the lug width of the Longines DolceVita L5.155.4.83.6?

The lug width is 15mm, a model-specific non-standard measurement. This narrower dimension maintains proportional coherence with the 19.80mm case diameter. Measure by positioning a ruler perpendicular to the lugs, calculating the internal distance between the two attachment points.

Which strap is most suitable for the Longines DolceVita L5.155.4.83.6?

Genuine alligator represents the most natural choice due to its fine, regular grain that respects the rectangular quadrant geometry. Vegetable-tanned calf offers more pronounced texture, whilst shell cordovan guarantees density and natural lustre. Each material develops patina over time, enriching the timepiece visually.

How do I change the strap on my DolceVita?

Position the watch on a soft surface with the caseback facing upward. Using a spring bar tool, gently press the lug spring to insert the tool tip into the housing. Move the tool downward to eject the bar, then remove the lug. Repeat on the opposite side. Insert the new strap by following the reverse procedure.

Can I use an aftermarket strap for the Longines L5.155.4.83.6?

Yes, provided the strap is specifically constructed for 15mm lugs. Standard 18mm or 20mm straps will not fit correctly, creating lateral play or excessive tension. Always verify that the internal passant corresponds exactly to the lug measurement.

How long does a leather strap last on this model?

An alligator or vegetable-tanned calf strap typically lasts 3-5 years with ordinary maintenance (periodic cleaning, avoiding prolonged immersion). Shell cordovan tends to last longer due to skin density. Actual durability depends on daily use, climatic conditions and object care.
