Strap for Elegant Collection 34.5 Automatic Stainless Steel / Red Gold / Silver

The lug width (or strap width) of the Longines Elegant L4.809.5.77.7 is 20 millimetres. This measurement is taken between the spring bar holes at the lugs, spanning shoulder to shoulder. The 20mm standard is one of the most widely supported dimensions in the aftermarket strap community, making sourcing artisanal replacements straightforward.

The optimal strap choice depends on the case variant: for the Red Gold version, an alligator in black or sienna brown elevates the watch's sophistication; for the stainless steel version, shell cordovan in burgundy or vegetable-tanned calf leather ensures uncompromised elegance. Navy NATO straps remain contemporary alternatives that preserve the watch's overall aesthetic coherence.

Strap replacement requires removal of the spring bars that connect the strap to the lugs. Use a spring bar tool, gently pushing the bar downward to disengage from the slot. Remove the old strap, position the new one, and reinsert the spring bars until you hear an audible click indicating secure seating. If inexperienced, a qualified watchmaker should perform this operation.

Yes, any strap with a 20mm lug width is compatible with the L4.809.5.77.7. MilanoStraps offers a dedicated range of artisanal leather, rubber, and textile straps, customisable in length, colour, initials, and thread choice. The Casati Milano atelier creates entirely bespoke straps with personalised colour consultation.

Leather strap longevity depends on frequency of wear and care standards. Premium alligator maintains structural integrity for 4–6 years under daily use; vegetable-tanned calf demonstrates comparable durability whilst developing an increasingly rich patina over time. High-density rubber offers greater longevity (5–7 years), whilst nylon NATO straps exceed 8 years. Regular maintenance and protection from extreme moisture significantly extend usable lifespan.
