Strap for Elegant Collection 25.5 Automatic Stainless Steel / Black / Strap

The lug width (misura ansa) of the Longines Elegant L4.309.4.57.2 is 13mm. This is a non-standard dimension, characteristic of many high-end women's watches, requiring bespoke strap designs. Measurement is taken between the two mounting holes on the case where the original steel lugs attach.

Alligator leather represents the most congruent choice, given its regular texture and the patina it develops with wear. Noble alternatives include vegetable-tanned calf leather (for durability and European character) and neutral-tone NATO fabric (for daily versatility). Rubber with micro-texture offers maximum practicality without compromising proportion.

Strap replacement requires a spring bar tool. Position the watch face-down, insert the tool tip into the lateral hole of the spring, press gently to release it, and slide out the original lug. Repeat on the opposite side. Then insert the metal ends of the spring into the corresponding holes on the new strap and press until you hear a click. If inexperienced, consult a professional watchmaker.

Yes, provided the strap is specifically designed for 13mm lug width. Many standard straps (14, 14.5, or 15mm) will not be compatible and may cause play or loosening. Always verify manufacturer specifications. Milano Straps supplies a complete collection of compatible 13mm straps in various materials and finishes.

A quality leather strap (alligator, vegetable-tanned calf) on a daily-worn watch has an average lifespan of 3-5 years. The determining factor is exposure to moisture and perspiration. With periodic maintenance (cleaning with damp cloth, complete drying) and rotation with other straps, longevity can extend to 7-8 years. A rubber strap maintains structural integrity beyond 5 years, even with intense wear.
