Strap for Elegant Collection Automatic 37 Stainless Steel / Red Gold / Silver

The Longines Elegant L4.810.5.77.7 features a lug width of 19 millimetres. This specific measurement requires bespoke strap manufacturing, as 19mm is not industry-standard. To verify the correct size, use a digital calliper on the inner shoulder of the lug.

For the L4.810.5.77.7, we recommend alligator leather in honey or cognac tones, which enhance the rose gold case finish. Shell cordovan in bordeaux represents an equally refined alternative. Vegetable-tanned calf leather develops exceptional patina over time. For summer wear, a NATO in premium linen or cotton offers a lighter aesthetic.

The Longines Elegant L4.810.5.77.7 uses standard spring bars: use a spring bar tool positioned perpendicularly to remove the bar, then insert the new strap's lugs through the opening. Ensure the spring bar is fully seated in both lug holes before releasing the tool.

Yes, any strap with 19-millimetre lugs is compatible. Milano Straps offers 19mm handcrafted straps customisable in material, colour and thread. Casati Milano creates bespoke straps with personal leather selection, WhatsApp updates and 18-month warranty.

A premium leather strap (alligator, shell cordovan, calf) typically lasts 4–7 years with daily wear and controlled aging. Durability depends on leather quality, frequency of use and care: protect from excessive moisture and dirt, clean periodically with a soft cloth. Vegetable-tanned leather develops visible patina, extending the strap's aesthetic lifespan.
