Strap for Conquest V.H.P. 43 Stainless Steel / Blue / Leather

The lug width of the Longines Conquest V.H.P. L3.726.4.96.0 is 22mm. This measurement represents the distance between the centres of the spring bar pins and is essential for selecting compatible aftermarket straps. Always verify the measurement using a digital calliper, measuring from pin centre to pin centre, to ensure proper installation without slack or structural stress on the case.

For the Conquest V.H.P., we recommend an alligator or calf leather strap with vegetable tanning in a dark brown shade. Florentine vegetable tanning allows natural patina development over time, enhancing the technical character of the watch. For sports environments or high humidity conditions, a FKM synthetic rubber strap is the ideal choice for durability and practicality without compromising resistance.

Use a spring bar tool, a specialised instrument that allows you to extract the elastic pins from the lug slots. Position the tool in the small notch of the pin, apply calibrated pressure to disengage the elastic end, then extract the strap from the case. Reverse the procedure to install the new 22mm strap, ensuring the pins are fully inserted into the slots and the strap adheres perfectly without any movement.

Yes, 22mm aftermarket straps are completely compatible with the Longines Conquest V.H.P. L3.726.4.96.0. Ensure the strap is genuinely sized for 22mm lugs and inspect the condition of the elastic pins before installation. Artisanally crafted straps guarantee superior build quality compared to OEM replacements, especially if made with vegetable tanning or natural materials of excellence.

The longevity of a leather strap depends on the material, tanning method, and daily wear. A vegetable-tanned artisanal strap typically lasts 3-5 years with daily use, developing natural patina that increases aesthetic value. Synthetic rubber maintains stable mechanical properties for 8-10 years. A shell cordovan strap can exceed 7 years without significant deterioration. The 18-month guarantee offered by Casati Milano covers manufacturing defects and ensures certified longevity.
