Strap for Conquest V.H.P. 41 Stainless Steel / Blue / Rubber

The lug width of the Longines Conquest V.H.P. L3.716.4.96.9 is exactly 20mm. This standard defines the distance between the two spring bar pins. Verifying this measurement with precision is essential: a 19mm strap creates tension, whilst a 21mm strap generates unwanted play.

For the Conquest V.H.P., we recommend bi-color alligator (black with grey undertones) for a sportive-elegant aesthetic, vegetable-tanned calf leather for natural patina development over time, or FKM rubber if frequent underwater use is anticipated. Your choice depends on context and dial colour variant.

Use a spring bar tool or small flathead screwdriver: insert the tool into the micro-hole adjacent to the pin, apply gentle pressure to compress the internal spring, then slide the pin out of the lug seat. Repeat on the opposite side. For installation, align the new strap with the lug holes and reinserт the pins until they click into place.

Yes, any strap with a 20mm lug width is compatible with the L3.716.4.96.9, regardless of manufacturer. Always verify that the width is exactly 20mm and that the lug passage thickness does not exceed 3.5mm, otherwise insertion into the case holes becomes problematic.

A high-quality artisanal alligator or calf strap, with moderate use (4–5 days per week), maintains structural and aesthetic integrity for 2–3 years. Vegetable tanned leather aging is natural; with proper care (periodic cleaning, air drying), longevity extends to 4 years. FKM rubber straps last considerably longer, 5–7 years.
