Strap for Conquest Classic Quartz 29.5 Stainless Steel / Blue

The lug width of the Longines Conquest Classic L2.286.4.92.6 is 15mm. This dimension represents the maximum width that a strap must have to fit correctly between the watch lugs, without gaps or wearing difficulty. Measuring the lug width requires a calliper or ruler positioned between the two lugs at the narrowest point, fully excluding the case shoulders.

The best strap for this timepiece depends on usage and personal preference. Black or dark brown alligator leather is the most elegant choice for formal contexts. Vegetable-tanned calf leather in cognac or burgundy offers durability and a patina that improves over time. Cognac shell cordovan represents the most sophisticated option for those desiring noble natural ageing. For daily wear, natural calf leather with subtle patina ensures comfort and colour versatility.

To change the strap, obtain a spring bar tool with two curved ends. Place the watch on a soft surface. Insert one end of the spring bar tool into a hole beneath a lug, gently pushing toward the case centre to release the internal spring. Repeat on the other lug. Remove the strap. To fit the new strap, position the spring bars into the appropriate holes, ensuring both lugs are securely fastened. If inexperienced, consult a qualified watchmaker.

Yes, you can fit aftermarket straps compatible with 15mm lug width, provided they are crafted by established quality ateliers. Milano Straps offers customisable straps in premium leather—alligator, calf, shell cordovan—that deliver aesthetic superiority over OEM straps without compromising durability or finish quality. Always verify that the strap is specified for 15mm lug width and features reinforced double stitching.

Leather strap longevity varies based on material, usage, and maintenance. A quality calf leather strap lasts typically 2–4 years with moderate daily wear. Alligator and shell cordovan, owing to their natural robustness, exceed 5 years even with frequent use. Vegetable-tanned leather tends to dry faster and requires periodic hydration. With occasional wear and correct storage (dry, away from heat sources), any strap can last 7–10 years. The 18-month warranty offered by Casati Milano covers manufacturing defects.
