Strap for Conquest V.H.P. 41 PVD / Black / Bracelet

The lug width of the Longines Conquest V.H.P. L3.716.2.56.6 is 20 millimetres. This measurement defines the internal space between the two lugs of the case and determines the compatibility of any strap. To verify correct measurement, use a digital calliper positioned perpendicularly between the internal lugs. An incorrect measurement—easily confused with the 22 mm of larger Conquest models—compromises strap fit.

The ideal strap depends on intended use. Natural alligator represents the most sophisticated compromise for those appreciating patina that evolves over time and marked geometric texture. High-quality calf leather, especially vegetable-tanned, offers tactile softness and the pigmentation characterising noble skins. Structured rubber is recommended for robust daily use. NATO in Cordura maintains Conquest's sporty identity with maximum practicality. We recommend against shell cordovan, whose mirror-like patina contradicts the watch's functional intent.

Strap replacement requires two springbar removal tools. Hold the old strap with one hand, position the tool in the small depression beneath the lug, press gently towards the case centre until the pin retracts, remove the old strap. Repeat on the other side. Insert the new strap aligning the holes with the pins, using the tool to compress the internal spring. Verify the strap is secure by pulling gently. The operation takes approximately 2 minutes for experienced users.

Yes, any strap with 20mm lug width is mechanically compatible with the Conquest V.H.P. L3.716.2.56.6. However, consider aesthetic coherence: the Conquest is a sports-classic watch, so straps in natural alligator, calf leather, or structured rubber align perfectly. Avoid straps in very formal or elegant materials, such as highly polished shell cordovan, which would contradict the model's functional identity. Mechanical compatibility does not always imply stylistic compatibility.

The lifespan of a leather strap depends on material, use, and maintenance. Natural alligator, if treated with protective wax every 6–8 months, achieves 3–4 years of daily wear before showing significant wear signs. Vegetable-tanned calf lasts 2–3 years if not exposed to intense perspiration and humid environments. Structured natural rubber offers superior resistance, up to 4–5 years. All leather straps benefit from periodic rest (rotation with other straps) and protection from excessive moisture. Casati Milano's artisanal straps include an 18-month warranty for manufacturing and craftsmanship defects.
