Frequently asked questions

What is the lug width of the Longines DolceVita L5.255.0.71.7?

The lug width of the Longines DolceVita L5.255.0.71.7 is 15 mm. This measurement is critical for strap compatibility: measure it by positioning a calliper between the inner shoulders of the case at the point where the spring bar sits. Any deviation from 15 mm indicates a different model or previous restoration work.

Which strap is recommended for the Longines DolceVita L5.255.0.71.7?

For the DolceVita L5.255.0.71.7, alligator in dark shades (black, dark brown) is recommended as its uniform grain enhances the case's geometric simplicity without visual competition. Alternatively, vegetable-tanned calf leather offers authenticity and develops a natural patina over time. For sport interpretations, a neutral silk or cotton NATO is appropriate.

How do I change the strap on the Longines DolceVita L5.255.0.71.7?

To change the strap, remove the spring bars from the lugs. Use a spring bar tool to push the bar on one side and slide the existing strap out of the lug. Reverse the procedure to install the new 15 mm strap. If unfamiliar with this procedure, consult a professional watchmaker to avoid case damage.

Can I use an aftermarket strap on the Longines DolceVita L5.255.0.71.7?

How long does a leather strap last on the Longines DolceVita L5.255.0.71.7?
