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

The lug width of the Longines Elegant L4.809.5.72.7 is 20 millimetres. This measurement is model-specific and represents the internal distance between the two lateral lugs of the case. It must be measured from shoulder to shoulder of the metal seat, not to be confused with case thickness or overall case width. Any compatible strap must strictly respect this specification to ensure correct attachment and absence of lateral play.

For the Longines Elegant L4.809.5.72.7, the most suitable straps are those in cognac or dark brown alligator, which enhance the harmony of the bi-material case. Alternatively, a strap in bordeaux shell cordovan imparts a natural patina that ages magnificently over time. For intensive daily use, a NATO strap in dark blue or grey maintains aesthetic sobriety. The choice depends on the balance between desired formal elegance and practical daily use.

Strap replacement is accomplished by removing the spring bars that connect the strap to the case lugs. Using a dedicated spring bar remover or small lever, apply pressure from below upward on one of the bars until release, then fully extract the old strap. The new strap must be aligned with the lugs and the bars reinserted manually, verifying that they engage evenly on both sides. Never use hammers or inappropriate tools.

Yes, the Longines Elegant L4.809.5.72.7 accepts any quality aftermarket strap with a 20-millimetre lug width, provided the internal width is compatible and the spring bars insert without forcing. Straps in alligator, shell cordovan, calf, NATO and rubber produced by specialised craftsmen guarantee perfect compatibility whilst maintaining elevated aesthetic and construction standards.

The durability of a leather strap depends on the quality of tanning and intensity of use. A superior quality alligator strap or vegetable-tanned shell cordovan can last 5–7 years with ordinary care and daily wear, developing a desirable patina. A calf aniline strap typically lasts 3–5 years, whilst a NATO canvas and synthetic leather strap can exceed 10 years. Direct sunlight exposure, excessive humidity and perspiration accelerate ageing. The 18-month warranty on bespoke straps from Casati Milano covers manufacturing defects, not natural wear.
