Strap for Elegant Collection 34.5 Automatic Stainless Steel / White / Strap

The Longines Elegant L4.809.4.12.2 features a 19 mm lug width. This measurement is the standard for all straps compatible with this model. To verify, measure the distance between the two lug seats (holes) where the strap attaches to the case. An incorrect measurement would result in an incompatible strap that cannot be fitted.

For this classical model, we recommend straps in alligator or vegetable-tanned calf, which maintain formal elegance without overwhelming the contained proportions of the case. A black alligator strap creates severity, whilst a vintage calf in tobacco tones introduces warmth. For less formal occasions, a NATO canvas strap in grey or navy blue offers versatility whilst retaining sobriety.

The strap is changed by extracting the spring bars that bind the strap to the lug seats. Use a dedicated tool (spring bar tool) to depress the small spring and slide the bar: the process requires care to avoid scratching the case. The new strap should be positioned aligned with the lug seats and the bar reinserted until it clicks into place. If inexperienced, consult Casati Milano for professional fitting.

Yes, provided the lug width is strictly 19 mm. Aftermarket straps of quality, crafted by Italian manufacturers such as milanostraps.it, often offer materials superior to standard options (authentic alligator, vegetable-tanned calf, full-grain leather). Always verify the measurement before ordering and check reviews regarding compatibility.

The lifespan of a leather strap depends on usage and material quality. A vegetable-tanned calf, worn daily, lasts 18–30 months before showing signs of structural wear. Authentic alligator resists 2–3 years or longer. Patina and imperfections are desirable characteristics, not defects. Casati Milano guarantees their straps for 18 months.
