Frequently asked questions

What is the lug width of the Longines Conquest V.H.P. L3.728.2.76.9?

The lug width is 32 millimetres. This is the standard distance between the case lugs. Measure precisely using a digital calliper positioned perpendicularly between the two attachment points, centre to centre.

What is the best strap for the Conquest V.H.P. L3.728.2.76.9?

The best strap depends on usage. French or American alligator is ideal for formal settings, vegetable-tanned calf offers balance between refinement and durability, whilst shell cordovan guarantees structural longevity and vitreous patina over time. For sports, technical rubber or NATO straps provide functionality without aesthetic compromise.

How do I change the strap on this watch?

The Conquest V.H.P. uses standard lugs with spring bars. Use a dedicated spring bar tool to compress the spring and remove the bar from one lug terminal, then withdraw the strap. Insert the new strap aligning its end to the terminal, reintroduce the bar whilst compressing the spring, and verify the lock. Avoid forcing to prevent damage to the lugs.

Can I use an aftermarket strap on this Longines?

Yes, entirely. Any strap with a 32mm lug width is compatible. Ensure the strap width (thickness) is proportionate to the case; generally, for a 43mm diameter, widths between 18 and 24 millimetres are recommended. Bespoke leather straps offer total personalisation of leather type, colour and stitching.

How long does a leather strap last on a sports watch like the Conquest?

Durability depends on leather quality and usage. Vegetable-tanned calf typically lasts 3–5 years with daily wear; shell cordovan can exceed 10 years. Alligator offers intermediate durability (5–7 years). Humidity, perspiration and UV exposure accelerate deterioration. An 18-month warranty is the artisanal standard for manufacturing defects.
