Strap for Conquest Heritage 40 Stainless Steel / Green

The lug width of the Longines Conquest Heritage L1.650.4.02.2 is exactly 20 millimetres. This is the standard measurement you must observe when selecting any compatible aftermarket strap. To verify the measurement yourself, use a flexible ruler positioned horizontally in the lug recess on the case: you will measure precisely 20mm from the inner edge of one side to the other. milanostraps.it offers a comprehensive collection of 20mm straps specifically curated for this model.

The ideal strap depends on your intended use and aesthetic preferences. For formal elegance and exceptional durability, alligator is the classical choice. For natural ageing and patina that improves over time, select vegetable-tanned calf leather. If you seek maximum resilience with historical character, shell cordovan delivers unparalleled toughness. For a sportive and vintage approach, a NATO in cotton or canvas aligns perfectly with the model's tool-watch identity. On milanostraps.it, personalise your choice according to available colours and your lifestyle needs.

Strap replacement requires minimal tools and care. Obtain a spring bar tool and position the watch case-side upward. Insert the thin end of the spring bar tool into the small groove on one side of the spring bar at the lug, then gently push inward to release the spring. Once both spring bars are disengaged, the old strap separates cleanly. To fit the new strap, align the lugs with the spring bar holes and gently push until you feel the reassuring click as the spring bar resets. If you prefer to avoid any risk, the Casati Milano atelier offers rapid mounting service by appointment.

Yes, a comprehensive range of aftermarket straps compatible with 20mm lug width is available. milanostraps.it's collection is regularly updated with options in alligator, calf leather, shell cordovan, NATO, rubber and fabric materials. Every strap offered is mechanically verified for compatibility and construction quality. You can personalise width, initials and stitching type. The Casati Milano atelier additionally creates bespoke straps with personal hide selection and 18-month warranty, available by appointment.

Leather strap longevity depends on material grade, construction quality and frequency of wear. A quality vegetable-tanned calf strap, worn daily, typically performs for 3–5 years before wear compromises function. Shell cordovan is notably more resilient and can deliver 7–10 years of service. Alligator, with its naturally robust grain, offers comparable durability. milanostraps straps are constructed with multiple-row stitching and carefully selected hides, ensuring above-average longevity. The 18-month warranty on Casati Milano straps covers manufacturing defects and latent faults, whilst natural leather wear is considered patina and character.
