Strap for Elegant Collection Automatic 39 Stainless Steel / Grey / Bracelet

The lug width of the Longines Elegant L4.910.4.72.6 is 20 mm. This measurement refers to the distance between the two attachment points (lugs) on the case where the strap fastens. When purchasing a replacement strap, always verify that the width matches exactly 20 mm to ensure a perfect fit without play or forcing.

For the Longines Elegant L4.910.4.72.6, we recommend alligator leather in natural brown tones or vegetable-tanned calf leather that develops a rich patina over time. Alligator preserves the minimalist elegance with its delicate rectangular grain, whilst natural calf develops character through aging. For versatility, an FKM rubber strap in black with a deployant clasp is a contemporary choice that does not compromise the classic style of the case.

The Longines Elegant L4.910.4.72.6 features fixed lugs (without spring bars). To replace the strap, use a lug removal tool: insert the tip into the hole and gently push the pin until it exits the opposite side. Once the pin is removed, the old strap detaches easily. To install the new strap, align the holes and reinsert the pin carefully. If unsure, consult a certified watchmaker.

Yes, provided the strap measures exactly 20 mm lug width. Milanostraps offers bespoke leather straps compatible with your L4.910.4.72.6, crafted in superior materials and fully customisable. What matters is verifying that the pin hole diameter matches the original Longines pins (typically 1.2 mm). Quality aftermarket straps do not alter the watch's mechanics.

A quality artisanal leather strap typically lasts 3–5 years with moderate daily wear, and up to 7–8 years with occasional use and regular maintenance. Durability depends on climate conditions (humidity, UV exposure), frequency of use, and care (protection from water and dirt). A vegetable-tanned leather strap ages gracefully and can last longer if treated with protective applications periodically. Milanostraps provides straps with 18 months warranty and recommends periodic maintenance to maximise longevity.
