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

The lug width of the Longines Elegant L4.810.5.11.7 is 19 millimetres. This precise measurement is critical when purchasing a strap: straps with a smaller opening may sustain damage during installation, whilst straps with a larger opening will present undesirable lateral movement. We recommend always verifying the strap specifications before purchase.

For the Longines Elegant L4.810.5.11.7, we recommend natural alligator in cognac colour or vegetable-tanned calf leather in bordeaux. Alligator enhances the classical elegance of the rose gold and steel case, whilst calf leather develops a personal patina over time. For daily wear, a slate-grey NATO strap offers practicality without sacrificing the formal rigour of the timepiece.

To replace the strap, you must remove the spring bars connecting the strap to the watch lugs. Use a spring bar tool: insert the fine wire into the lateral hole of the lug, compress the internal spring and slide the bar outward carefully. Exercise caution to avoid scratching the case. If you lack experience, consult a jeweller or the Casati Milano atelier for professional installation.

Yes, provided the strap has a 19-millimetre lug width. Milano Straps artisanal straps are constructed to this specific geometric specification and are fully compatible. Always verify that the manufacturer certifies the exact measurement: a tolerance of 0.5 millimetres may compromise installation.

Longevity depends on material and usage patterns. High-quality alligator, worn daily, withstands 4-6 years before requiring replacement. Vegetable-tanned calf leather lasts 3-5 years with more visible wear. Canvas NATO straps exceed 10 years. Exposure to perspiration, direct sunlight and humidity accelerates ageing. The 18-month warranty provided by Casati Milano covers manufacturing defects and ordinary wear.
