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

The lug width of the Longines Conquest V.H.P. L3.726.4.56.3 is 22 millimetres. This parameter represents the external distance between the two pins that anchor the strap to the case. It is essential to verify this measurement before purchasing a replacement strap, as even a minor discrepancy would result in mechanical incompatibility.

For the Conquest V.H.P. L3.726.4.56.3, we recommend three primary options: alligator for those seeking a patina that naturally evolves over time, Tuscan calf with vegetable tanning for those prioritising construction solidity and elegant ageing, and butyl rubber for those preferring functionality and water resistance. The choice depends on intended use and personal aesthetic preferences.

Strap replacement is achieved by removing the spring bars that connect the lugs to the case. Use a dedicated spring bar tool to apply gentle pressure to one of the pins, extracting it completely. Once the first lug is free, repeat the procedure on the second pin. Install the new strap by reversing the process, ensuring the pins are correctly positioned and the lugs adhere perfectly to the case.

Yes, the Longines Conquest V.H.P. L3.726.4.56.3 is fully compatible with high-quality aftermarket straps, provided they respect the 22-millimetre lug width. Straps crafted from alligator, calf, shell cordovan, or rubber integrate perfectly into the watch case, allowing aesthetic and functional variations without compromising mechanical compatibility.

A high-quality leather strap, crafted with vegetable tanning and artisanally constructed, has an average lifespan of 3–5 years under normal usage conditions. Longevity depends on factors such as humidity exposure, frequency of use, and maintenance. Alligator or Tuscan calf straps, owing to fibre solidity, tend to last longer, especially if subjected to periodic maintenance with products specifically formulated for leather.
