Frequently asked questions

What is the lug width of the Longines Presence L4.790.2.11.2?

The lug width (misura ansa) of the Longines Presence L4.790.2.11.2 is 20 millimetres. This is the precise distance between the two strap attachment pins on the case. To verify, measure perpendicularly between the case lugs: it should be exactly 20 mm.

Which strap material is most suitable for the Longines Presence L4.790.2.11.2?

The Presence L4.790.2.11.2 pairs perfectly with alligator in dark shades (black, mahogany brown), vegetable-tanned calf in natural colours (honey, raw leather, hazelnut), or shell cordovan for those accepting chromatic evolution over time. For daily wear, a woven NATO strap or FKM rubber maintains design discretion whilst offering versatility.

How do I change the strap on my Longines Presence L4.790.2.11.2?

Obtain a spring bar removal tool. Position the watch on a stable surface, locate the metal pins beneath the lugs, insert the tool tip into the small lateral notch on the pin, press inward to release the outer pin, repeat on the opposite side. Insert the new strap pins in the same manner, ensuring they click fully into position.

Are 20 mm aftermarket straps truly compatible with the Longines Presence L4.790.2.11.2?

Yes, any strap with a 20 mm lug width is compatible. The specificity of this measurement (20 mm rather than 18 or 22) ensures precise engagement with the original attachment pins. Verify the strap is genuinely 20 mm by measuring yourself, as 1 mm variations cause instability.

How long does a leather strap last on the Longines Presence L4.790.2.11.2?

A premium leather strap (alligator, calf, shell cordovan) crafted by skilled artisans typically lasts 3-5 years with daily use, influenced by sun exposure, humidity, and frequency of replacement. Vegetable-tanned straps develop desirable patina with age. A quality bespoke aftermarket strap includes 18-24 month warranty against manufacturing defects.
