The Conquest V.H.P. L3.729.4.96.6, seen from the bench

The Longines Conquest V.H.P. L3.729.4.96.6 is the contemporary evolution of a sports line born in 1954. The V.H.P. (Very High Precision) movement features certified accuracy of ±5 seconds per year through a thermally-compensated quartz caliber, outperforming standard quartz watches. The 43mm stainless steel case houses the Longines L288.2 quartz movement with thermal compensation, displaying hours, minutes, seconds, and date. With a 22mm lug width, this model balances generous proportions while maintaining comfort and aesthetic versatility on the wrist.

Frequently asked questions

What is the lug width of the Longines Conquest V.H.P. L3.729.4.96.6?

The lug width (or strap width) of the Longines Conquest V.H.P. L3.729.4.96.6 is 22mm, measured between the inner edges of the lugs where the strap connects to the case. This dimension ensures harmonious proportions with the 43mm case diameter and provides access to a comprehensive range of artisanal strap options. Always verify your watch's exact lug width before ordering a replacement strap.

Which strap is best suited for the Longines Conquest V.H.P. L3.729.4.96.6?

For this high-precision sports timepiece, we recommend a 22mm Tuscan vegetable-tanned leather strap for daily urban wear, or genuine alligator for more formal occasions. If your Conquest sees frequent outdoor activity, a black FKM elastomer or nylon ripstop NATO strap delivers superior resilience. A titanium deployante buckle perfectly balances the weight of the stainless steel case.

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

The Longines L3.729.4.96.6 uses standard spring bars to attach the strap to the lugs. Obtain a ball-point spring bar tool: insert the tip into the lateral slot of the spring, apply gentle pressure to compress the spring, and extract the pin. Repeat on the opposite lug. Position the new strap vertically with the lug holes, then press firmly until the spring bar locks into place. The procedure requires only seconds and no specialised equipment.

Is a 22mm aftermarket strap compatible with the Conquest V.H.P. L3.729.4.96.6?

Yes, provided it is manufactured for the 22mm lug width specification. All Milano Straps artisanal straps in the 22mm collection are fully compatible with the Longines L3.729.4.96.6. Ensure that the strap thickness (2.5–4mm, depending on material) creates no visible gaps at the case-lug junction. Vegetable-tanned and alligator leathers deliver the finest aesthetic results on this model.

How long does a leather strap last on a daily-wear watch?

A high-quality artisanal vegetable-tanned calf leather strap, worn daily with moderate care, develops an enchanting patina after 2–3 months and maintains structural integrity for 3–5 years. Genuine alligator extends this longevity to 7–8 years. Durability depends on exposure to moisture, chlorine, and perspiration: rinse gently with fresh water after sea bathing and allow to air-dry away from direct heat sources. Casati Milano provides an 18-month warranty and professional regeneration services.
