Frequently asked questions

What is the lug width of the Longines Presence L4.790.4.11.2?

The lug width of the Longines Presence L4.790.4.11.2 is 30mm. This is the internal distance between the two metal lug holes on the case. It is essential to respect this measurement precisely when ordering an aftermarket strap, as lug widths of different dimensions would not guarantee secure attachment.

Which strap is recommended for the Longines Presence L4.790.4.11.2?

For the Presence, we recommend natural alligator, which amplifies the sober elegance of the watch. Alternatively, smooth calf leather in dark brown tones (cognac) or burgundy shell cordovan represent excellent choices. Each material will develop a unique patina over time, further enriching the aesthetic of the watch.

How do you change the strap on a Longines Presence L4.790.4.11.2?

To change the strap, you must remove the spring bars that connect the strap to the lugs. Using a dedicated tool (spring bar remover), gently push the pin inward until one end of the strap is released, then repeat on the other side. Installing the new strap follows the reverse procedure.

Can I use a quality aftermarket strap on my Longines Presence L4.790.4.11.2?

Certainly. Aftermarket natural leather straps, provided they are constructed with a 30mm lug width, are fully compatible. We recommend consulting specialised manufacturers, such as those available on Milano Straps, who guarantee construction quality, precise finishing, and warranty coverage.

How long does a natural leather strap last over time?

Durability depends on usage and care. A quality leather strap, with regular maintenance (gentle cleaning, protection from excessive moisture), maintains functionality and aesthetics for 3-5 years. Natural leather develops a characteristic patina over time, which increases the aesthetic value of the accessory, even if visibly worn.
