Frequently asked questions

What is the correct lug width for the Longines DolceVita L5.155.4.79.2?

The Longines DolceVita L5.155.4.79.2 requires a strap with a lug width of 15mm. This specific measurement is a distinctive characteristic of the model and is not compatible with the more common 16mm or 18mm standards. To verify the width, use a digital calliper positioned between the inner shoulders of the case lugs: you will find precisely 15mm.

Which type of strap is best suited to the DolceVita L5.155.4.79.2?

Given the Art Déco and minimalist nature of the DolceVita L5.155.4.79.2, the ideal material is alligator with vegetable tanning for those who appreciate natural texture, or aged calf leather for those who desire a more uniform surface that develops patina over time. Shell cordovan represents a premium alternative for wrists requiring structure and durability. The most versatile colour is cognac brown or absolute black.

How do you change the strap on the Longines DolceVita L5.155.4.79.2?

The strap is replaced by removing the spring bars that connect the strap to the case lugs. Use a dedicated tool (spring bar tool) to compress the internal pin and extract it from the lug. Next, position the new 15mm strap by aligning the holes with the lugs and reinsert the pins, ensuring they click perfectly into place. If you are unsure of the procedure, consult a qualified watchmaker.

Which aftermarket straps are compatible with the DolceVita L5.155.4.79.2?

All straps with a 15mm lug width are compatible with the DolceVita L5.155.4.79.2. Milano Straps offers a complete collection of artisanal 15mm leather straps in alligator, calf, shell cordovan and canvas, all customisable in length, colour and thread. Casati Milano atelier also manufactures bespoke straps with full styling consultation via WhatsApp.

How long does a leather strap last on the DolceVita L5.155.4.79.2?

A quality leather strap, crafted with vegetable tanning, has an average lifespan of 4-6 years of daily wear, provided proper maintenance is carried out (rapid drying in case of accidental moisture contact, storage in a dry environment). Shell cordovan ages better and can last 7-10 years. Durability depends on frequency of use and climatic conditions. Milano Straps straps include an 18-month warranty against manufacturing defects.
