Strap for Conquest 38 Stainless Steel / Black / Bracelet

The lug width of the Longines Conquest L3.720.4.52.6 is 19 millimetres. This measurement is taken from centre to centre of the case attachment points, on the interior side of the lugs. A strap incompatible with this width will not fit correctly and will compromise the watch's aesthetic balance.

The best strap depends on intended use and personal preference. For a classic pairing, we recommend vegetable-tanned alligator or calf leather. For a sportier option, shell cordovan or textured FKM rubber maintains the technical character of the Conquest. The Casati Milano atelier can guide you through direct consultation on leathers, colours, and finishes.

Strap removal is accomplished using a spring bar tool. Position the tool in the lateral slots of the lug, apply gentle pressure to compress the internal spring, and slide the bar outward. Repeat on the opposite side. The new strap must have a 19mm lug width to attach correctly. If inexperienced, consult a professional watchmaker.

Yes, any aftermarket strap with a 19 millimetre lug width is compatible with the Longines Conquest L3.720.4.52.6. milanostraps.it offers handcrafted, customisable straps in premium leathers (alligator, calf, shell cordovan). Always verify that the lug width matches your attachment points precisely.

Leather strap longevity depends on use, material, and maintenance. An alligator or vegetable-tanned calf strap, worn daily with proper care, typically lasts 3–5 years. Shell cordovan, being denser, can exceed 7 years. Excessive humidity, heat, and prolonged sun exposure accelerate ageing. Casati Milano guarantees 18 months on bespoke straps, covering manufacturing defects.
