Frequently asked questions

What is the lug width of the Longines DolceVita L5.255.0.71.4?

The lug width is 15mm, measured as the distance between the metal attachment pins to the case. To verify it, use a digital calliper positioned perpendicularly between the case guides. Milano Straps offers a complete range of compatible 15mm straps for this model.

What is the best strap for the DolceVita?

For the Art Déco aesthetic of the DolceVita, we recommend vegetable-tanned alligator, which develops patina over time, or shell cordovan for those preferring a smooth, lustrous surface. Calf box represents an elegant and more sustainable compromise. Choice depends on personal style and frequency of use. Casati Milano offers personalised consultations.

How do I change the strap on my Longines DolceVita?

Strap replacement is straightforward: using a watchmaker's tool, remove the pins, extract the old strap, clean the pins and caseback with a soft cloth, then insert the new strap, aligning it perfectly. Ensure the pins are parallel and the strap sits symmetrically. We recommend professional assistance for first-time changes.

Can I use an aftermarket strap for my Longines DolceVita?

Yes, provided the lug width is exactly 15mm. Milano Straps guarantees full compatibility of our straps, customisable in length, initials, and thread colour. Artisanal straps provide superior quality compared to original equipment.

How long does a leather strap last on this watch?

With moderate use (wrist 4-5 days per week), an alligator or cordovan strap lasts 18-24 months. Calf box, being more delicate, lasts 12-18 months. The patina that develops is part of the beauty. Casati Milano guarantees 18 months and offers reconditioning and leather renewal services.
