Frequently asked questions

What is the lug width of the Longines Conquest V.H.P. L3.728.4.96.9?

The lug width is 32 millimetres. This measurement represents the space available between the two lugs of the case and is determined by the constructive proportions of the 43mm model. For accurate measurement, use a digital calliper and measure only the central space, excluding the lugs themselves.

What is the best strap choice for the Longines Conquest V.H.P.?

The choice depends on personal use and preference. For sports elegance, we recommend an alligator strap in black or slate grey. For daily versatility, a calf leather with vegetable tanning in cognac brown or pearl grey guarantees durability and distinctive patina development over time. NATO straps in premium canvas remain a functional and versatile solution, particularly suited to casual contexts.

How do I change the strap on a Longines Conquest V.H.P.?

Changing the strap on the Longines Conquest V.H.P. requires a dedicated tool to remove the lug pins. Place the watch on a soft surface, locate the small pin on one side, use a spring bar remover tool to apply pressure and extract it carefully. Once the lug is freed, the strap slides away easily. Repeat on the other side. Reinsert the pin into the new strap with precise and controlled movements.

Which aftermarket straps are compatible with the L3.728.4.96.9 reference?

All straps with a 32mm lug width are fully compatible with the Longines Conquest V.H.P. L3.728.4.96.9. Milano Straps offers a comprehensive collection of premium leathers (alligator, calf, shell cordovan), NATO canvas straps and customisable straps, with the possibility to choose lengths, initials, stitching colour and buckle type.

How long does a leather strap last on a Longines Conquest?

The lifespan of a leather strap depends on usage intensity, environmental conditions and construction quality. A calf leather with vegetable tanning, properly maintained, typically lasts 3–5 years of moderate daily wear. An alligator or shell cordovan strap can extend longevity to 7–8 years. Frequent exposure to water, direct sunlight and humidity significantly shorten strap life. Premium canvas NATO straps, by contrast, require minimal maintenance and last longer.
