Strap for Elegant Collection 25.5 Automatic Stainless Steel / White / Bracelet

The lug width of the Longines Elegant L4.309.4.11.6 is 13mm. This measurement must be verified with a calliper, measured from the inner base of one lug to the other, parallel to the case axis.

For this model, alligator is recommended for discreet elegance, shell cordovan for chromatic depth and durability, vegetable-tanned calf for natural patina development, and silk-linen NATO for informal versatility. The choice depends on predominant use and desired aesthetic tone.

The strap is changed by removing the spring bars with a dedicated tool. Position the tool beneath the spring, apply controlled pressure to retract it, extract the pin. Insert the new strap and reinsert the pin until it clicks into position, verifying it is firmly secured.

Yes, any strap with a 13mm lug width is compatible. It is essential to verify the width with a calliper before purchase to avoid play or interference. Milanostraps offers customisable 13mm straps ready for dispatch and bespoke service via Casati Milano atelier.

A premium leather strap (alligator, cordovan, vegetable-tanned calf) typically lasts 3–5 years with daily wear, varying based on tanning, UV exposure and ambient humidity. Vegetable tanning ages developing patina; alligator maintains chromatic stability. Casati Milano guarantees 18 months on bespoke straps.
