The Conquest V.H.P. L3.729.4.96.9, seen from the bench

The Longines Conquest V.H.P. L3.729.4.96.9 is a contemporary evolution of a line established in 1954 with the first sports chronograph in history. This 43mm stainless steel model features the L288.2 quartz movement (V.H.P. stands for Very High Precision), offering ±5 seconds per month accuracy. The watch combines legibility and robustness with a satin-finished steel case, sapphire crystal, and a 22mm lug width that balances proportions and enables generous strap thickness without marring the case.

Frequently asked questions

What is the lug width of the Longines Conquest V.H.P. L3.729.4.96.9?

The lug width is exactly 22mm. You must source straps with a 22mm lug width to ensure compatibility. To verify, measure the distance between the two metal pins protruding from the case sides—they must be exactly 22mm apart.

Which strap pairs best with the Longines Conquest V.H.P.?

The Conquest V.H.P. is a versatile tool watch. Alligator in navy or charcoal grey accentuates its sport-elegant profile; cognac or burgundy calf leather introduces warmth; premium NATO or FKM rubber is ideal for intensive use or aquatic environments. Your choice depends on personal style and intended usage.

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

Remove the spring bars that connect the strap to the case. Use a spring bar tool or small flat screwdriver. Gently press towards the case centre to compress the spring, pull the bar outward, and the strap will detach. Repeat on the opposite side. Mount the new strap by reversing the process.

Are there aftermarket straps compatible with the L3.729.4.96.9?

Yes. Since the lug width is the standard 22mm, you can use any artisanal or commercial strap of the same width. Vegetable-tanned leather, genuine alligator, gummed calf, or premium NATO straps guarantee full compatibility and offer extensive customisation freedom.

How long does a leather strap last on the Longines Conquest V.H.P.?

A quality leather strap (alligator, calf, vegetable-tanned) typically lasts 3–5 years of daily wear, depending on sun exposure, humidity, and care regimen. Strap replacement is straightforward and periodically recommended to maintain a fresh appearance and ensure structural integrity of the lugs.
