FAQ

What is the lug width of the Longines Presence L4.905.2.11.7?

The lug width of the Longines Presence L4.905.2.11.7 is 20 millimetres. This measurement is critical for strap compatibility: any 20mm strap will fit the lugs without play or mechanical obstruction.

What is the best strap for the Longines Presence L4.905.2.11.7?

The best strap depends on use case: alligator in brown for formal occasions, vegetable-tanned leather for those seeking patina evolution, textile NATO for daily versatility. The satin-brushed case finish pairs particularly well with structured leathers and regular textures.

How do I change the strap on the Longines Presence L4.905.2.11.7?

Strap removal requires a small spiral spring bar (spring bar tool) available from jewellers or specialist retailers. Insert the new strap into the lugs, verify alignment, and secure the spring. Avoid twisting motions that damage the lugs.

Can I use an aftermarket strap compatible with the Longines Presence L4.905.2.11.7?

Yes. Any strap with 20mm lug width is mechanically compatible. We recommend quality leathers (alligator, vegetable-tanned calf) to maintain aesthetic coherence and durability over time.

How long does a leather strap last on the Longines Presence L4.905.2.11.7?

A quality leather strap lasts 3–5 years with regular daily wear, depending on tanning method and maintenance frequency. Vegetable-tanned leathers, though more durable, require periodic conditioning to preserve flexibility and prevent cracking.
