What I'm asked about the Longines Conquest V.H.P. L3.729.4.56.9

What strap size does the Longines Conquest V.H.P. L3.729.4.56.9 take?

The Longines Conquest V.H.P. L3.729.4.56.9 needs 22 mm between the lugs, usually 18 or 20 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Longines Conquest V.H.P. L3.729.4.56.9 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the Longines Conquest V.H.P. L3.729.4.56.9?

Yes, in 22 mm leather. On a 43 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Longines Conquest V.H.P. L3.729.4.56.9?

A 22 mm calf strap, for every day. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

The Conquest V.H.P. L3.729.4.56.9, seen from the bench

Frequently asked questions

Which strap is the best choice for the Conquest V.H.P. L3.729.4.56.9?

The choice depends on intended use and personal preference. For sporty elegance, an alligator strap with vertical grain in deep black accentuates the technical character. For everyday versatility, a calf leather strap with vegetable tanning in cognac tones develops a captivating patina over time. For aquatic or intense sporting activity, a technical NATO strap in regenerated fibres or a dark grey FKM rubber strap offers practicality and absolute durability.

Is the Conquest V.H.P. L3.729.4.56.9 strap compatible with other models?

No, the 22mm lug width is specific to this model. Straps of 20mm or 24mm will not fit correctly: they may have excessive play or not insert at all into the lugs. Always verify the lug width before purchasing an aftermarket strap. Online retailers offer a wide selection of 22mm straps compatible with your Conquest.

How long does a leather strap last on a sports watch like the Conquest V.H.P.?

A quality leather strap, vegetable tanned, typically lasts 3–5 years with daily use, depending heavily on climate conditions and water exposure. An alligator strap with vegetable tanning ages more elegantly and can last 7–10 years. To maximise longevity, avoid prolonged exposure to moisture and clean the strap with a dry cloth. FKM rubber or NATO straps have superior durability—10–15 years—with minimal maintenance.
