Frequently asked questions

What is the lug width of the Longines Conquest V.H.P. L3.716.4.56.9?

The lug width of the Longines Conquest V.H.P. L3.716.4.56.9 is 20mm. This measurement represents the internal distance between the two lugs of the case and is the standard for sports watches with 40-42mm diameter. It is essential to verify this specification before purchasing an aftermarket strap.

Which strap should I choose for the Longines Conquest V.H.P. L3.716.4.56.9?

The best strap choice depends on usage. For minimal maintenance and sportiness, we recommend brown or black Nile alligator. For greater versatility, vegetable-tanned calf in blue or brown. For a casual, low-maintenance approach, a grey-green NATO in linen-cotton. All materials must be 20mm and compatible with 41mm diameter watches.

How do I change the strap on the Longines Conquest V.H.P. L3.716.4.56.9?

Changing the strap is straightforward: obtain a spring bar tool (available online), position the bifurcated end in the spring bar holes on the case sides, apply gentle pressure to push the pins out, and remove the old strap. Insert the new strap, aligning it with the spring bars, and press until the spring bars re-engage in the lateral slots. The procedure takes 2-3 minutes without damaging tools.

Can I use an aftermarket strap on this Longines?

Yes, provided the width is exactly 20mm. Quality-certified aftermarket straps (alligator, calf, NATO) are fully compatible. Always verify the vendor's specification. Straps from milanostraps.it are tested for compatibility on this reference and include personalised sizing adjustments.

How long does a leather strap last on the Longines Conquest V.H.P.?

Leather strap durability depends on usage, climate, and maintenance. With standard care (avoiding water exposure and storing dry), an alligator strap lasts 5-8 years; vegetable-tanned calf 4-6 years. Chlorine and saltwater reduce life by 30-40%. A Tropic rubber strap resists 3-5 years in hot, humid climates before deteriorating. Casati Milano offers an 18-month warranty on all custom-made straps.
