Strap for Conquest 34 Stainless Steel - Pink Gold / Purple / Rubber

The lug width of the Longines Conquest L3.430.5.98.9 is 17 millimetres. This is an intermediate size, not standard in conventional lug width conventions (16mm or 18mm), reflecting the proportional design specific to the 34mm case. To verify it, measure the distance between the internal holes of the lug seat with a digital calliper, positioning yourself at the centre of the attachment.

For the Conquest L3.430.5.98.9, straps are recommended that balance the hybrid rose gold-stainless steel aesthetic. Porosus alligator (natural grain) combines sportiness and refinement. Vegetable-tanned calf leather (dark havana, seal brown) develops patina harmonious with gold. NATO in cotton-nylon (black or navy blue) honours the model's sporting heritage. FKM rubber for humid or saline environments. Avoid bright or pastel colours: the model requires chromatic sobriety.

Strap replacement requires a spring bar tool (single or double-lever instrument). Position the tool under the small spring (spring bar) that supports the strap at the side of the case, push downward to compress the spring, extract the old strap. Repeat on the other side. Insert the new strap by threading the lugs into the holes and verifying that the spring clicks fully into seat. Manually snap with the thumble for security.

Yes. Many artisan strap manufacturers (including milanostraps.it) offer 17mm straps ready in stock and customisable. Always verify that the strap is certified as 17mm in width; 16mm or 18mm straps generate unacceptable mechanical play. High-quality aftermarket straps maintain construction standards identical to original Longines straps.

A high-quality alligator or calf leather strap (vegetable tanning) lasts 5–7 years with moderate daily wear, up to 10 years with rotation (frequent changing). Lifespan depends on factors: exposure to saltwater and humidity (reduces life by 30–40%), maintenance (gentle cleaning and periodic conditioning), frequency of use. FKM rubber straps last 8–12 years. Cotton-nylon NATO straps age well but wear faster with daily wear (3–4 years). Casati Milano's 18-month warranty covers manufacturing defects.
