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

The lug width of the Longines Conquest L3.320.5.92.6 is 15mm. This measurement represents the distance between the two pins that connect the strap to the watch case. It is a critical dimension to ensure strap compatibility and must be verified accurately before purchasing any aftermarket strap.

For the Conquest L3.320.5.92.6, we recommend textured leather straps—alligator, Taurillon calf, or shell cordovan—to highlight the two-tone steel and rose gold elegance. For a sportier approach, NATO fabric or FKM rubber offer functional versatility. Brown or cognac alligator amplifies rose gold reflections; navy or black calf creates clean, refined geometric contrast.

Changing the strap requires a spring bar tool. Position the tool underneath the metal pin securing the strap to the lug, apply light pressure to compress the internal spring, and slide the pin out of the lug. Repeat for both sides. Insert the new strap by aligning the pins with the holes, and ensure they click securely into position. If unsure, consult a professional watchmaker to avoid case damage.

Yes, any strap with a 15mm lug width is compatible with the Conquest L3.320.5.92.6. Milano Straps offers a dedicated catalogue of artisanal 15mm straps ready for dispatch, customisable in leather, colour, size and stitching thread. The Casati Milano atelier also creates bespoke straps with personalised material and colour consultation.

Longevity depends on leather type, usage and maintenance. A quality artisanal calf or alligator strap typically lasts 3–5 years of moderate daily wear. Leather develops natural patina and ages gracefully. To extend lifespan, avoid prolonged exposure to water, sweat and direct sunlight. Vegetable-tanned shell cordovan is among the longest-lasting, potentially exceeding 7–8 years. Milano Straps guarantees 18 months on Casati Milano straps, with professional repair options available.
