Strap for Conquest 30 Stainless Steel - Pink Gold / Green / Bracelet

The lug width of the Longines Conquest L3.320.5.02.6 is 15mm. This measurement represents the distance between the inner shoulders of the spring bar lugs on the case. It is essential to respect this exact measurement when purchasing an aftermarket strap, as a wider or narrower lug width will not be compatible with the case attachments.

The optimal strap depends on intended use and personal preferences. For formal elegance, alligator in honey or cognac tones enhances the rose gold warmth of the case. For daily versatility, a vegetable-tanned calf leather in taupe-brown offers natural ageing and patina development. For summer sportive wear, a NATO canvas in navy blue or cement grey maintains proportion without excess. All must respect the 15mm lug width specification.

Strap replacement requires basic tools: a spring bar tool or watchmaker's pin. Position the watch on a soft surface (microfiber cloth), locate the side spring bar lugs, insert the tool beneath the spring to release it, extract the bar, and repeat on the other side. Install the new strap into the lugs, ensuring the springs engage correctly. Avoid forcing to prevent case scratching.

Yes, absolutely. Any strap with a 15mm lug width is mechanically compatible. We recommend selecting high-quality leathers and finishes (alligator, calf, Shell Cordovan) to match the watch's construction standard. A bespoke artisanal strap further elevates the ownership experience and aesthetic longevity of the timepiece.

Leather strap lifespan depends on material quality, tanning method, and usage frequency. A vegetable-tanned alligator or Shell Cordovan, if exposed to moderate moisture and maintained regularly (cloth cleaning, annual conditioning), averages 5–7 years before replacement becomes necessary. Ordinary calf may last 3–4 years. Constant exposure to humidity, chlorine (pools) or salt water (marine) significantly shortens this estimate. With a 30mm case like the L3.320.5.02.6, the strap is visually prominent: investing in leather quality is a logical choice.
