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

The lug width (distance between watch lugs) of the Longines Elegant L4.810.5.12.7 is 19 millimetres. This measurement is essential for selecting a compatible strap. You can verify it by measuring with a digital caliper the internal space where the strap attaches to the case.

For this two-tone rose gold and stainless steel model, we recommend black or dark brown alligator to maximise contrast, vegetable-tanned calf leather in cognac tones for a warm formal appearance, or a cotton NATO strap for daily versatility. Your choice depends on the tone you wish to emphasise: formal, contemporary, or sport-elegant.

You will need a spring bar tool to compress the spring pins at the strap ends. Position the tool in the small slot of the spring, compress inward, and slide the strap out of the lugs. Repeat on the other side. The process is reversible and requires no specialist skills, but if you prefer professional assistance, Casati Milano atelier performs changes by appointment.

Yes, any strap with a 19mm lug width is compatible with the Longines Elegant L4.810.5.12.7, provided the spring bars are of identical length and diameter. Milanostraps.it straps are engineered to this specification. Always verify the exact lug width before purchase to avoid misalignment.

Durability depends on leather quality, frequency of use, and environmental conditions. High-quality alligator or vegetable-tanned calf typically lasts 3–5 years with daily wear in temperate climates. Frequent exposure to water, perspiration, and heat accelerates deterioration. Milanostraps.it straps include an 18-month warranty; Casati Milano atelier offers maintenance and replacement guidance.
