Frequently asked questions

What is the lug width of the Longines Conquest V.H.P. L3.729.4.76.9?

The lug width of the Longines Conquest V.H.P. L3.729.4.76.9 is 22mm. This measurement refers to the distance between the inner edges of the spring bars that attach the strap to the case. To verify compatibility, measure with callipers the distance between the two lugs: it must be exactly 22mm. Browse our catalogue of compatible straps for this specific width.

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

For the Longines Conquest V.H.P., we recommend straps crafted from vegetable-tanned leather such as Tuscan calf in tobacco or cognac, or alligator for enhanced elegance. For a more sporty aesthetic, rubber or NATO fabric 22mm straps are excellent choices. The quality of the leather must reflect the technical excellence of the movement: avoid low-quality synthetic materials. The ideal buckle is stainless steel with a deployant clasp for ease of wear.

How do I change the strap on my Longines L3.729.4.76.9?

Changing the strap is a straightforward operation. Place the watch on a soft surface and locate the two spring bars (the side pins that pass through the case lugs). Using a small tool (spring bar tool), gently press inward on one of the pins to release the old strap. Repeat on the other side. Insert the new strap by leveraging the pins until they lock completely. Ensure the strap is perfectly aligned with the lugs. If you feel uncertain, contact our Casati Milano atelier for professional strap replacement.

Can I use an aftermarket 22mm strap on this watch?

Yes, the Longines Conquest V.H.P. L3.729.4.76.9 is compatible with any quality aftermarket 22mm strap. The universal 22mm lug width allows for a wide range of materials, colours and styles. Always verify that the strap has the correct dimensions and that the spring bars are solid and functioning properly. Milano Straps offers a curated collection of 22mm straps designed for luxury watches such as your Conquest, featuring artisanal leathers and professional finishes.

How long does a natural leather strap last on a watch like this?

A quality natural leather strap with vegetable tanning lasts an average of 3–5 years under regular wear, provided it receives proper care: avoid prolonged exposure to water, excessive perspiration and direct heat. The patina that develops over time is a noble characteristic of natural leather. With proper maintenance and periodic cleaning, a Casati Milano strap with 18-month warranty performs exceptionally. To extend the life of the strap, it is recommended to alternate it with a second strap, allowing the leather to breathe between uses.
