Strap for Elegant Collection 34.5 Automatic Stainless Steel / Black / Strap

The lug width of the Longines L4.809.4.57.2 is 19 millimetres. This measurement is taken between the two spring bar holes located at the case extremities and represents the compatibility standard for all aftermarket straps designed for this model.

For the Longines L4.809.4.57.2 we recommend alligator in black or navy blue for formal elegance, or vegetable-tanned calf leather in tobacco for daily warmth and character. FKM rubber represents the sporting option with exceptional grip. Choice depends on use: formal, daily business, or casual-sports.

Strap replacement requires a spring bar tool to extract the fixing pins. Position the tool in the lateral groove of the pin, apply controlled pressure and the pin will withdraw from the case. Insert the new strap aligning the pins and verify the fixing is secure. If uncertain, contact a professional strap-change service.

Yes, any strap with a 19mm lug width is compatible with the Longines L4.809.4.57.2. Artisanal aftermarket straps of superior quality often offer more refined materials and finishes than original straps, guaranteeing personalisation and durability equivalent to or exceeding the original.

A premium leather strap (alligator, calf, shell cordovan) lasts an average of 3–5 years with daily use and routine maintenance. Shell cordovan, thanks to its natural hardness, reaches 8–10 years. Longevity increases if the strap is worn non-consecutively and regularly cleaned with specialist products.
