Frequently asked questions

What is the lug width of the Longines DolceVita L5.155.4.73.2?

The lug width of the Longines DolceVita L5.155.4.73.2 is 15mm. This non-standard dimension reflects the refined proportions of the rectangular case, ensuring a harmonious transition between the watch's main body and the strap. To verify your lug width, measure the internal distance between the case lugs using a calliper—you should find exactly 15mm.

Which strap is best suited for the Longines DolceVita L5.155.4.73.2?

For the DolceVita, alligator leather is the natural choice thanks to its characteristic grain that dialogues perfectly with the geometric purity of the case. Shell cordovan excels for formal occasions, offering an enchanting patina and superior substance. Vegetable-tanned calf represents a modern, sustainable alternative, whilst vulcanised rubber is ideal for daily wear in humid environments or during sporting activities.

How do I change the strap on my Longines DolceVita L5.155.4.73.2?

To change the strap, use a spring bar tool to extract the elastic pins that hold the strap to the case lugs. Begin on one side, inserting the tool into the small opening beneath the pin; once the pin is extracted, you can remove the old strap. Insert the new 15mm strap by aligning the holes, then reinsert the elastic pins, ensuring they are firmly seated on both sides.

What aftermarket strap is compatible with the Longines DolceVita L5.155.4.73.2?

Any strap with a 15mm lug width is compatible with the DolceVita L5.155.4.73.2, provided the material and thickness do not exceed the case's constructive parameters. Milano Straps offers a dedicated collection of 15mm straps in alligator, shell cordovan, calf and rubber, all customisable in sizing, initials and stitching thread choice, guaranteeing a precise fit without lateral play.

How long does a leather strap last on a Longines DolceVita?

The lifespan of a leather strap depends on the material and usage. An alligator or shell cordovan strap, with normal wear and proper maintenance (avoiding prolonged moisture, cleaning with a soft cloth), lasts 4-7 years. Vegetable-tanned calf typically lasts 3-5 years, whilst vulcanised rubber can exceed 8 years. Casati Milano offers an 18-month warranty on all custom-made straps created in the atelier.
