Frequently asked questions

What is the exact lug width of the Longines Presence L4.321.2.45.2?

The lug width of the Longines Presence L4.321.2.45.2 is 13mm. This measurement refers to the internal space between the lugs of the case where the strap attaches. It is essential to verify this dimension before purchasing an aftermarket strap by using callipers or checking the official Longines documentation.

Which strap do you recommend for the Longines Presence L4.321.2.45.2?

For the Longines Presence L4.321.2.45.2, we recommend alligator or shell cordovan straps for formal occasions, thanks to their natural texture and capacity to develop patina over time. For daily wear, smooth calf or fine-grained leather offers practicality whilst maintaining elegance. Premium fabric NATO straps represent a contemporary option for those who alternate lifestyles.

How do I change the strap on the Longines Presence L4.321.2.45.2?

Changing the strap on the Longines Presence L4.321.2.45.2 requires specific tools: a spring bar tool or extractor pin for the suspension pins. Position the watch on a stable surface, locate the small side holes in the lugs, then gently push the internal pin outward. Once extracted, the old strap will slide off. Insert the new strap by aligning it with the lugs and snap the pin into position. If uncertain, consult a specialist watchmaker or contact Milano Straps for assistance.

Is the Longines Presence L4.321.2.45.2 compatible with 13mm aftermarket straps?

Yes, the Longines Presence L4.321.2.45.2 is fully compatible with any aftermarket strap with a 13mm lug width. Milano Straps offers a curated selection of artisanal straps in this measurement, all tested for mechanical compatibility with Longines lugs. Always verify that the strap is explicitly listed for 13mm lug width.

How long does a leather strap last on the Longines Presence L4.321.2.45.2?

The lifespan of a leather strap depends on the material and usage. Alligator and vegetable-tanned shell cordovan maintain structural integrity for 5-8 years of moderate use, developing an appreciated patina over time. Smooth calf has similar longevity under regular wear conditions. Durability is extended by proper maintenance: avoid excessive moisture, apply protective balm every 6-12 months, and store in a dry location. Milano Straps straps include an 18-month warranty against manufacturing defects.
