Frequently asked questions

What is the lug width of the Longines Conquest V.H.P. L3.727.4.66.9?

The lug width of the Longines Conquest V.H.P. L3.727.4.66.9 is 22mm. This dimension is standard for sports chronographs in this category and must be verified precisely before purchasing an aftermarket strap. A digital calliper is recommended to measure the space between the spring bar pins.

Which strap is most suitable for the Longines Conquest V.H.P. L3.727.4.66.9?

For this 44mm case with white dial and black counters, the following are recommended: vegetable-tanned Tuscan leather (cognac or dark brown), chocolate brown or black alligator, or medium shell cordovan for those seeking durability. Avoid excessively glossy finishes; prefer surfaces with natural grain that develops over time.

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

Use a spring bar removal tool. Position the watch on a stable surface, gently open the spring bar from below with the tool, applying slight leverage until it retracts, then remove the strap. Repeat on the other side. To install the new strap, align the spring bars with the lugs and press until a secure click is felt.

Can I use an aftermarket strap with my Longines Conquest V.H.P. L3.727.4.66.9?

Yes. All 22mm straps are compatible. Milano Straps offers straps in Tuscan leather, alligator, and other certified materials, customizable in length and finishes. For a perfect fit, Casati Milano (atelier by appointment) creates custom straps after direct evaluation of your wrist and case.

How long will the leather strap on my Longines Conquest V.H.P. last?

A vegetable-tanned Tuscan leather strap lasts an average of 4-6 years with moderate daily wear. Shell cordovan can exceed 8 years. Durability depends on maintenance (clean regularly, avoid constant humidity exposure) and climate. Milano Straps guarantees 18 months on Casati Milano custom straps, with possibility of reconditioning thereafter.
