Strap for Avant-Garde Quartz Big Date Black / Bracelet

The lug width is 20 millimetres. This measurement is essential for selecting a compatible aftermarket strap. To verify the correct dimension, remove the spring bar from the lugs (the two small holes on the case sides) and check that it measures exactly 20mm. Any aftermarket strap must respect this specification to ensure perfect fit without play or friction.

The optimal strap depends on intended use and personal preference. For formal and elegant daily contexts, we recommend an alligator strap with vegetable tanning: the textured grain dialogues perfectly with the brushed stainless steel case and develops natural patina over time. For durability and versatility, vegetable-tanned calf leather offers superior robustness with deep patina development. For aquatic environments and sports, an FKM rubber strap guarantees performance without compromise. Heavy cotton NATO straps are ideal for those who enjoy rapid aesthetic changes.

The process is straightforward and requires no special tools. Observe the two small holes (lugs) positioned on the case at the ansa level. Insert a thin, rounded object (such as a toothpick tip or dedicated tool) into one hole and gently push the spring bar upward until it extracts. Repeat on the other side. Once removed, the strap separates easily. Install the new strap by inserting the spring bar into the new strap's holes and the case lugs, ensuring it sits firmly in place.

Yes, absolutely. Any strap with a 20mm lug width is compatible. Milano Straps offers a curated selection of artisanal-quality aftermarket straps tested for the Eterna Contemporary 2545.41.40.1715: noble leather (alligator, calf), NATO straps, and technical rubber straps. All our straps are crafted from premium materials with certified workmanship. Always verify lug width before purchase to guarantee perfect compatibility.

A high-quality artisanal leather strap (alligator or calf) with moderate daily use and proper maintenance has a lifespan of 3 to 5 years. Longevity depends on several factors: direct sunlight exposure, humidity, perspiration, and frequency of wear. Vegetable-tanned leather is more durable than chemically tanned varieties. To extend strap life, avoid prolonged saltwater immersion, clean regularly with a soft cloth, and occasionally apply leather balm. When the strap shows signs of tip deterioration or buckle wear, it is time to replace it.
