Frequently asked questions
What is the exact lug width of the Longines Conquest V.H.P. L3.719.4.56.6?
The lug width (ansa width) of the Longines Conquest V.H.P. L3.719.4.56.6 is precisely 20 mm. This unconventional measurement should be verified by measuring the internal distance between the two notches where the strap attaches. A undersized strap (19 mm) will cause friction in the spring bar channels; an oversized strap (22 mm) will not achieve secure seating in the lugs.
Which strap is most suitable for the Longines Conquest V.H.P. L3.719.4.56.6?
The ideal strap depends on use case. For daily elegance: alligator in medium brown with vegetable tanning, or Italian calfskin leather. For longevity and conscious ageing: vintage cordovan leather. For professional humid or military contexts: rubber or grey-blue NATO strap. The ceramic and stainless steel case accommodates both refined leather and tactical functionality.
How do you change the strap on a Longines Conquest V.H.P. L3.719.4.56.6?
Use a spring bar removal tool to gently extract the spring bars securing the strap to the lugs. Position the tool tip in the small hole beneath the spring, lift slowly until the bar releases, then remove the strap. Repeat on the opposite lug. To install a new strap, align the holes with the lugs and reinsert the spring bars until they seat fully with an audible click.
Is an aftermarket 20mm strap compatible with the Longines Conquest V.H.P. L3.719.4.56.6?
Yes, any 20 mm strap with standard spring bars is fully compatible. MilanoStraps offers handcrafted 20mm straps in alligator, calfskin, shell cordovan, and rubber, customisable in final length and stitching thread. Casati Milano atelier provides bespoke straps with personal leather selection and 18-month guarantee, ideal for optimising comfort and aesthetic alignment.
What is the lifespan of a leather strap on the Longines Conquest V.H.P. L3.719.4.56.6?
Lifespan varies by material: quality Italian calfskin lasts 2–3 years of daily wear; shell cordovan extends to 5–8 years or beyond thanks to fibre density and natural patina development; vegetable-tanned alligator typically serves 3–4 years with visible ageing; rubber straps endure 1–2 years with proper maintenance. Humidity, perspiration, and UV exposure affect ageing. Rotating between multiple straps extends overall longevity significantly.
