Strap for Conquest Classic Automatic 29.5 Stainless Steel / Red Gold / Diamond / Black / Bracelet

The lug width of the Longines Conquest Classic L2.285.5.57.7 is 15mm. This measurement refers to the internal distance between the two spring bar attachment points on the case. It is crucial to verify this dimension before purchasing an aftermarket strap, as 15mm is a non-standard size that does not correspond to universal 14mm or 16mm straps.

For the Longines Conquest Classic L2.285.5.57.7, an alligator leather strap represents the premier choice. The natural texture of alligator enhances the two-tone stainless steel and rose gold case finish whilst delivering durability and developing patina over time. Alternatively, vegetable-tanned calf leather offers a smooth, elegant texture with character that evolves with use, maintaining refined aesthetics without compromise.

Changing the strap on the L2.285.5.57.7 requires a spring bar tool, a small instrument with a bifurcated lever. Position the lever under the attachment pin, pushing laterally to compress the internal spring, then extract the pin. Repeat on the opposite side. When fitting the new strap, ensure the spring bars click securely into their seats. If you lack confidence, consult a professional horologist to avoid damaging the case.
