Frequently asked questions

What is the lug width of the Longines Presence L4.778.6.32.6?

The Longines Presence L4.778.6.32.6 features a lug width of 18 mm. This measurement allows you to fit straps compatible with this specific dimension. Always verify manually with callipers that the strap inserts correctly without forcing.

Which strap is most suitable for the Longines Presence in yellow gold?

For a Presence in yellow gold, an alligator strap is the traditional choice that enhances its luxury without heaviness. Vegetable-tanned calf leather offers a more intimate alternative with an evolving patina over time. Black, dark brown, and cognac tones are the most harmonious colours for this model.

How do I change the strap on a Longines Presence?

To change the strap, use a spring bar tool to gently remove the metal lugs (spring bars) that secure the strap to the case lugs. Apply light leverage from the bottom until you hear a click. Insert the new strap by aligning the holes with the spring bars and ensure it's properly secured on both sides. Avoid twisting during the operation.

Can I use an aftermarket strap on a Longines Presence L4.778.6.32.6?

Yes, provided it has the compatible 18 mm lug width. Quality aftermarket straps, such as those in alligator, calf or shell cordovan, fit the Presence perfectly whilst preserving its classic aesthetics. Verify that the lugs are compatible with the original spring bars.

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

A quality leather strap (alligator, calf, shell cordovan) typically lasts between 5 and 10 years with moderate daily use. Durability depends on exposure to moisture, sunlight and frequency of use. A vegetable-tanned strap deteriorates gracefully, developing a fascinating patina. Standard warranty is 18 months.
