Frequently asked questions

What is the lug width of the Longines Presence L4.321.2.45.8?

The lug width of the Longines Presence L4.321.2.45.8 is 13mm. This is a rare and specific dimension for this model, requiring dedicated straps. To verify compatibility, measure the internal distance between the lugs on your watch case: the strap must pass smoothly without excessive lateral play. A measurement error can damage both the case and the strap.

What is the best strap for the Longines Presence L4.321.2.45.8?

The best strap depends on your intended use and aesthetic preferences. For a classic and elegant result, we recommend alligator leather in medium-dark brown (cognac, toffee) or natural shell cordovan, both of which develop a beautiful patina over time. For formal occasions, a black smooth calf leather strap is ideal. For daily wear, a satin-finished calf leather with natural patina offers durability and visual restraint.

How do I change the strap on the Longines Presence L4.321.2.45.8?

Position the watch on a clean, slightly elevated surface. Use a spring bar removal tool or a thin implement: insert it into the side opening of the lug to release the internal spring. Gently pull outward to extract the spring bar. Repeat on the other side. Align the new strap's holes with the case attachments and reinsert the spring bar until you feel it click into place. Never force the operation, as the stainless steel case of the Présence is refined and sensitive to damage.

Can I use an aftermarket strap on the Longines Presence L4.321.2.45.8?

Yes, provided the aftermarket strap has a lug width of 13mm and is constructed with quality comparable to the original. We recommend artisanal leather straps rather than generic products, which may not fit perfectly or deteriorate quickly. Always verify compatibility before purchase and ensure that the lugs are securely fastened.

How long does a leather strap last on the Longines Presence L4.321.2.45.8?

The lifespan of a leather strap depends on the material and usage intensity. An artisanal alligator strap typically lasts 3-5 years with daily wear before requiring replacement, while shell cordovan may last 4-6 years. Natural calf leather has a lifespan similar to alligator. With regular maintenance (gentle cleaning, quick drying after moisture exposure), the strap's lifespan extends considerably. Milano Straps leather straps include an 18-month warranty.
