Frequently asked questions

What is the lug width of the Longines Conquest V.H.P. L3.718.4.66.6?

The lug width is 20mm (measured from inside lug to inside lug). This intermediate width is characteristic of this model and should not be confused with the external case dimensions of 41mm. Before purchasing a strap, always verify the internal measurement with a calliper to ensure perfect compatibility.

Which strap pairs best with the Longines Conquest V.H.P.?

For this model we recommend African alligator with natural grain (enhances elegance whilst maintaining sportiness), two-toned satin-finished calf leather for day-to-evening versatility, or NATO in organic canvas for those prioritising functionality. The choice depends on intended use: formal suggests alligator or calf; casual/sporty suggests NATO or rubber.

How do you change the strap on the Longines Conquest V.H.P. L3.718.4.66.6?

The Conquest V.H.P. features an integrated case with straight lugs: removing the strap requires a spring bar tool inserted perpendicularly into the lug hole, applying steady pressure until the retention spring releases. If you lack experience, we recommend in-store support or remote guidance from Casati Milano via WhatsApp.

Is the Longines Conquest V.H.P. L3.718.4.66.6 strap compatible with aftermarket straps?

Yes, all 20mm straps are compatible thanks to the standard straight lugs. Milanostraps offers 20mm straps customisable in leather, colour, sizes and stitching thread, tested for perfect fit. Casati Milano also provides bespoke straps with personal consultation and 18-month warranty.

How long does a leather strap last on this watch?

Durability depends on material, tanning method and frequency of use. Satin-finished calf: 2–3 years in daily wear. Alligator: 4–5 years, ageing with noble patina. Shell cordovan: 3–4 years if kept dry. Vegetable tanning will mark naturally and darken over time, transforming the strap into a biographical object. Rubber and NATO have virtually unlimited lifespan if protected from extreme heat.
