Strap for Conquest Classic Moonphase Stainless Steel - Red Gold / Black

The lug width of the Longines Conquest Classic L2.798.5.52.3 is 21mm. This measurement represents the distance between the upper and lower spring bar pins where the strap attaches. To verify correctly, use a digital calliper perpendicular to measure from the centre of one pin to the centre of the other. Precise measurement is essential to avoid straps that are too tight or excessively loose.

For the rose gold and stainless steel bicolour of the Conquest Classic L2.798.5.52.3, we recommend a dark Hermès-grade alligator strap for formal occasions, or a cognac-vintage shell cordovan for a sophisticated pairing that enhances rose gold reflections. For daily versatility, vegetable-tanned calf or FKM rubber ensures functionality and natural patina development over time.

Changing the strap requires a specialist tool (spring bar tool). Position the watch face-down and locate the spring bar pins within the lugs. Gently insert the spring bar tool to depress the pin and extract the old strap. Insert the new strap in the same manner, ensuring the pins click securely into place.

Yes. All straps with a 21mm lug width are compatible. milanostraps.it offers complete collections of handcrafted, customizable straps for your model: alligator, vegetable-tanned calf, shell cordovan, NATO and rubber. Casati Milano also provides bespoke service with personal leather selection and dedicated updates.

Leather strap longevity depends on material and wear. A quality alligator or shell cordovan with vegetable tanning typically lasts 3–5 years of daily wear before replacement. Vegetable-tanned calf develops natural patina and is valued even after 7–8 years of use. Casati Milano guarantees 18 months on bespoke straps, and the material ages beautifully when occasionally treated with protective wax.
