Strap for Conquest Automatic 39

The Longines Conquest L3.656.4.96.2 features a 19-millimetre lug width. This intermediate measurement is characteristic of the model and ensures aesthetic balance between elegance and robustness. To verify your watch's lug width, measure the internal distance between the two pins connecting the case to the strap using a digital calliper.

The choice depends on intended use. For formal elegance, we recommend alligator with fine grain or vegetable-tanned calf leather in medium brown tones. For daily versatility, a canvas NATO offers practicality without aesthetic compromise. Rubber is ideal if you wear the watch in variable environments. At milanostraps.it you'll find 19mm straps in all these materials, fully customisable.

The process is straightforward: use a springbar tool to gently compress the lateral pin, releasing the old strap from the case. Repeat from the other side. Insert the new strap by aligning one lug first, then the other, ensuring the pins lock correctly. Avoid sudden movements during the operation to prevent scratching the case.

Yes, absolutely. The key is choosing straps with compatible lug width (19mm) and superior build quality. At milanostraps.it you'll find artisanal leather straps in premium hides, robust stitching and refined finishing that integrate perfectly with the Conquest's instrumental character, often surpassing the original strap in character.

A quality leather strap—crafted with vegetable tanning or authentic alligator—typically lasts 3-5 years with daily wear, depending on maintenance and moisture exposure. Shell cordovan tends to last longer, up to 7-10 years. At milanostraps.it we offer 18-month warranty on all artisanal straps; the Casati Milano atelier provides consultancy to extend your strap's lifespan through tailored maintenance.
