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

The lug width of the Longines Conquest V.H.P. L3.719.4.96.6 is 20mm. This measurement represents the internal distance between the two lugs of the case and is the fundamental parameter for selecting a compatible strap. Measuring the lug width correctly means positioning the strap perpendicular to the case and verifying the internal space between the contact points; a tolerance of ±0.5mm is acceptable, but millimetre-perfect correspondence is ideal.

For the 41mm Conquest V.H.P., several options are recommended depending on context. Alligator leather (vegetable or aniline tanned) represents the most refined choice, with natural texture that complements the stainless steel and ceramic case. Satin or grained calf leather offers practicality and chromatic versatility. Shell cordovan guarantees extraordinary durability and a developing patina over time. For intensive aquatic use, vulcanised FKM rubber or NATO fabric remain the most resistant options. Your choice depends on your lifestyle and predominant use context.

Changing the strap on a Longines Conquest V.H.P. requires simple tools: a spring bar tool or small screwdriver. Insert the thin blade between the lug and the pin securing it, gently press downward to release the internal spring, and pull the pin towards you. Once both pins are removed, the strap separates from the case. Install the new strap by reversing the operation: insert the pins into the housings and press until you feel the spring click. If you are uncertain, consult a professional watchmaker or Casati Milano atelier for precise replacement.

Yes, aftermarket straps are completely compatible with the Longines Conquest V.H.P. L3.719.4.96.6, provided they respect the 20mm lug width. Quality artisanal straps, such as those crafted by Casati Milano or available on milanostraps.it, often feature superior materials (alligator, shell cordovan, vegetable leather) compared to the original strap. Customisation through aftermarket straps allows you to adapt the watch to your personal style and seasons, whilst maintaining full technical compatibility and ensuring optimal fit.

The durability of a leather strap depends on the tanning type, frequency of wear and environmental conditions. A quality alligator or calf leather strap with vegetable tanning can last 3–5 years with moderate daily wear. Shell cordovan, due to its structural density, may resist for 5–7 years or more. Aniline or vegetable leather straps develop patina over time and tend to wear faster (2–3 years) if exposed to intense moisture and friction. To extend strap life, avoid prolonged water immersion, clean regularly with a soft cloth, and occasionally apply protective creams specific to leather. Rubber straps have greater durability but may lose elasticity after 4–6 years of sustained use.
