Strap for Elegant Collection Automatic 39 Stainless Steel / White / Strap

The lug width of the Longines Elegant L4.910.4.11.2 is 20 millimetres. This dimension is specific to this model and ensures perfect proportions between the 39mm case and the strap. To verify compatibility, measure the distance between the two lugs (lateral attachments) from inner edge to inner edge.

For the Longines Elegant L4.910.4.11.2, we recommend alligator for classic elegance, vegetable-tanned calf for a sustainable and durable choice, or ballistic nylon NATO for contemporary practicality. The choice depends on your intended use and desired aesthetic profile: each material modulates the character of the watch whilst maintaining sober proportion.

To change the strap, use a spring bar tool to gently remove the elastic pins that secure the strap to the lugs. Compress the pin slightly towards the case centre, withdraw the strap and repeat on the other side. To install the new strap, align the first spring bar, secure the strap, then position the second pin. Avoid hammers or inappropriate tools.

Yes, any strap or bracelet with a 20-millimetre lug width is compatible with the Longines Elegant L4.910.4.11.2. Artisanal aftermarket straps, if constructed with solid methods (double stitching, premium leather), often offer superior aesthetic customisation compared to original straps. Always verify the lug width before purchase.

A premium leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years under normal daily-use conditions, meaning moderate exposure to moisture and mechanical stress. Longevity increases if the strap is dried after water contact and stored away from constant humidity. Artisanal straps from Casati Milano include an 18-month warranty.
