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

The lug width of the Longines Conquest Classic L2.285.5.87.7 is 15mm. This dimension represents the width of the case lug, the space between the two attachment points for the strap. It is a compact measurement, consistent with the feminine proportions of the 29.50mm case, and requires careful selection of aftermarket straps to ensure correct compatibility.

For the Conquest Classic L2.285.5.87.7, the best strap choice is alligator in brown or vegetable-tanned calf leather. Dark brown or cognac alligator creates a sophisticated visual dialogue with the mother-of-pearl dial and warm tones of the rose gold. A vegetable-tanned calf in Prussian blue or burgundy offers a contemporary hue while maintaining elegance. Pure black straps are discouraged, as they would appear overly graphic for this model.

The strap is changed by removing the spring bars, the small metal pins that connect the strap to the case lugs. Using a spring bar tool (a thin, flat instrument), apply gentle pressure to compress the internal spring, slide the pin out of the lug, and repeat on the other side. Reverse the process to insert the new strap, ensuring the spring bars are fully inserted and locked.

Yes, the L2.285.5.87.7 is fully compatible with 15mm aftermarket straps. Milanostraps.it offers a complete collection of customisable 15mm leather straps in various materials and colours. Always verify the exact lug width before purchase to avoid incompatibility with the spring bars.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years with daily wear, depending on frequency of use and care. Leather exposed to moisture, heat, and perspiration deteriorates more rapidly. Alligator tends to outlast calf due to the natural structure of the scales. Casati Milano straps, crafted from selected leather with artisanal stitching, include an 18-month warranty and can be refurbished or replaced at the atelier.
