Strap for Elegant Collection Automatic 29 Stainless Steel / Grey / Bracelet

The lug width of the Longines Elegant L4.310.4.72.6 is precisely 20mm. This measurement represents the distance between the inner edge of one lug and the inner edge of the other, and must be verified accurately to ensure proper fitting of an aftermarket strap. An incorrect measurement results in straps that either do not fit into the lugs or sit loosely on the case.

For the Longines Elegant L4.310.4.72.6, an alligator strap with fine grain represents the most aristocratic choice, thanks to the natural elegance of the leather and its decade-long durability. Alternatively, vegetable-tanned calf leather develops a refined patina over time, whilst FKM rubber is ideal for those requiring moisture resistance and everyday practicality. The choice depends on intended use and personal aesthetic preferences.

To change the strap on your Longines Elegant L4.310.4.72.6, position the watch with the case facing upward and locate the spring bars securing the strap to the lugs. Using a dedicated spring bar tool, press gently inward on the bar to release one end, then remove the bar and strap. Repeat on the other side. Insert the new strap, aligning the holes to the 20mm lug width, and press until the bars lock into the lugs. If uncertain, consulting a certified watchmaker is always the prudent choice.

Yes, provided the aftermarket strap is specifically designed for a 20mm lug width. Compatible straps from specialised online suppliers guarantee correct fitting and secure attachment. Ensure the strap has attachments sized precisely for 20mm, and that the spring bars are the correct length for your L4.310.4.72.6 case. Quality manufacturers, such as those available on milanostraps.it, offer warranty and post-sale technical support.

Leather strap longevity depends on the type of leather and intensity of use. A high-quality alligator or vegetable-tanned calf strap typically lasts between 5 and 10 years with routine maintenance (periodic cleaning and protection from excessive moisture). Lesser-quality leather straps have an average lifespan of 2 to 4 years. Artisanal Casati Milano straps, crafted from carefully selected leathers, include an 18-month warranty and are engineered for superior longevity. With time, leather naturally patinas and stiffens, lending character to your timepiece.
