Frequently asked questions

What is the lug width of the Longines DolceVita L5.255.0.87.0?

The lug width of the Longines DolceVita L5.255.0.87.0 is 15 millimetres. This specific width is characteristic of this rectangular model and is essential when selecting a compatible strap. It is measured by calculating the internal distance between the two lugs where the strap attaches.

What is the best strap for the Longines DolceVita L5.255.0.87.0?

For the DolceVita L5.255.0.87.0, alligator leather with fine grain represents the most suitable choice, in shades such as dark brown, black, or midnight blue. An alternative of equal quality is Italian calf leather with vegetable tanning for a natural patina that evolves over time. Shell cordovan offers exceptional durability and a colour that deepens over the years.

How do I change the strap on the Longines DolceVita L5.255.0.87.0?

To change the strap, position the watch on a soft surface. Use a spring bar tool or small rod to gently lift the retaining pins on each lug. Carefully remove the old strap, align the new strap with the lugs and reinsert the pins. Verify that the strap is securely fastened before wearing.

Can I use an aftermarket compatible strap with the Longines DolceVita L5.255.0.87.0?

Yes, quality aftermarket straps with 15mm lug width are fully compatible. Milano Straps offers bespoke leather straps with 15mm width, customisable in leather type, colour and finishing. It is advisable to verify technical compatibility and select high-quality materials to match the excellence of your watch.

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

A quality artisanal leather strap, whether vegetable-tanned or alligator, will last 3-5 years with daily use, depending on care and material selection. Premium leathers such as shell cordovan can last over 10 years. Regular maintenance with appropriate creams significantly extends the lifespan of the strap.
