Frequently asked questions

What is the exact lug width of the Longines Presence L4.790.2.12.2?

The lug width of the Longines Presence L4.790.2.12.2 is precisely 20.00 mm. This measurement must be taken on the interior of the horizontal lugs, from wall to wall. It is essential to order a strap with this exact dimension to ensure correct fitting without lateral play.

Which strap material is best suited for the Longines Presence L4.790.2.12.2?

For the Presence L4.790.2.12.2, we recommend natural alligator or vegetable-tanned calf leather. Alligator elevates formality with its articulated grain, whilst vegetable-tanned calf develops an elegant patina over time. For more versatile use, natural crocodile in black remains the incisive choice, guaranteeing extraordinary durability and depth.

How do you change the strap on a Longines Presence L4.790.2.12.2?

The strap is secured to the horizontal lugs via spring bars that fit into their slots. To change the strap, remove the existing bars by pushing them inward with a spring bar remover tool. Once the lugs are freed, insert the new 20 mm strap whilst maintaining perpendicularity to the dial. We recommend having a professional execute this operation to avoid scratches on the case.

Is the Longines Presence L4.790.2.12.2 compatible with quality aftermarket straps?

Yes, the Presence L4.790.2.12.2 is fully compatible with superior quality aftermarket straps. Simply order a strap with a 20 mm lug width and confirm the Longines model to the manufacturer to ensure constructive compatibility. Straps in alligator, vegetable-tanned calf, or shell cordovan will guarantee secure fitting and correct aesthetic proportions.

How long does a leather strap last on a Longines Presence L4.790.2.12.2?

A superior quality leather strap (alligator, crocodile, shell cordovan) lasts approximately 8-12 years with daily wear, developing a patina that narrates the passage of time. Vegetable-tanned calf typically endures 5-7 years, ageing in a predictable and captivating manner. Longevity depends on ambient humidity, frequency of use, and leather care. Natural rubber or technical fabric straps offer superior durability in humid environments.
