Strap for Conquest 30 Stainless Steel / MOP - Diamond / Bracelet

The lug width of the Longines Conquest L3.320.4.87.6 is 15mm. This measurement is essential for selecting a compatible strap and ensuring precise mounting on the case lugs. You can verify it by measuring the distance between the two lugs with a digital calliper or by consulting the official Longines documentation.

For the Conquest L3.320.4.87.6, alligator leather represents the finest choice in terms of formality and natural texture, ideal for elegant settings. Vegetable-tanned calf leather offers superior versatility, allows for natural patina development, and provides excellent durability. For a sporty approach, a canvas NATO maintains coherence with the model's DNA. FKM rubber is recommended for those prioritising practicality and daily resilience.

Changing the strap requires the use of a springbar tool or a professional watchmaker's tweezers. Apply gentle pressure on the lateral lugs to release the metal pin holding the original strap. Once freed, align the new strap with the lug holes and reinsert the pin with equal care. If you lack specialist tools, it is advisable to contact a watchmaker or Milano Straps' strap-change service.

A premium leather strap (alligator or vegetable-tanned calf) worn daily has an average lifespan of 3–5 years before replacement or restoration is required. Longevity depends on usage context, climatic conditions, and leather care. Milano Straps straps are crafted from first-quality hides and include an 18-month warranty; the Casati Milano atelier provides assistance and restoration even after the warranty period expires.
