Frequently asked questions

What is the lug width of the Longines Presence L4.804.2.11.8?

The Longines Presence L4.804.2.11.8 has a lug width of 18 mm. This measurement is taken between the two inner pins that support the strap. It is an international standard that allows for a wide choice of compatible aftermarket artisanal straps.

What strap is best suited for the Longines Presence L4.804.2.11.8?

For a watch of this proportional elegance, an alligator strap with vegetable tanning is the most refined choice: the regular grain and thin leather enhance the case's proportions. Alternatively, structured taurillon veal offers versatility whilst maintaining formality, whilst a cotton NATO strap allows for rapid transformations and a casual atmosphere.

How do I change the strap on my Longines Presence?

To change the strap, you must remove the two pins (sprung bars) that support it. Using a small, flat tool (a dedicated tool or a small knife blade), gently press the pin upwards to release the old strap. Insert the new strap by aligning the side holes with the pins and press until the retention click engages.

Can I use an aftermarket strap on this model?

Yes, absolutely. The Longines Presence L4.804.2.11.8 with 18 mm lug width is compatible with any strap manufactured to the international standard for this width. Artisanal milanostraps.it straps are fully customisable in leather, size and details, ensuring a precise fit.

How long does a leather strap last on a daily-wear watch?

A quality leather strap, subjected to moderate daily use, has an average lifespan of 3 to 5 years before requiring replacement. Vegetable-tanned leather ages better and develops a natural patina that increases aesthetic value. A Casati Milano strap comes with an 18-month warranty and maintains a solid structure over time thanks to carefully selected materials.
