Strap for Conquest Heritage 40 Stainless Steel / Brown

The lug width is 20mm. This dimension is essential for compatibility with any aftermarket strap. To verify, measure the distance between the lugs at the case horns: it must be exactly 20mm between the inner edges of the holes. This is the standard width for mid-size sports chronographs.

For a chronograph with this sporting DNA, we recommend genuine alligator for tactical elegance, satin calf for daily versatility, canvas NATO for absolute reliability in high-wear environments, and FKM rubber for aquatic contexts. Choice depends on your primary use case and colour sensitivity: dark leathers deepen contrast with luminous indices, light textiles soften sporting tension.

The procedure requires a dedicated tool (spring bar tool or thin screwdriver). Insert the tool into the small lateral hole under the case lug, near the pin that holds the strap, and gently push to extract the pin. Repeat on the other side. Install the new strap by inserting the pin into the opposite holes, ensuring it is well-seated. If you prefer to avoid risk of scratching, entrust the task to a professional watchmaker.

Yes, any strap with a 20mm lug width is compatible. Online you will find options in alligator leather, calf, shell cordovan, NATO canvas, and specialised rubber. Milano Straps offers a curated collection of 20mm straps ready for dispatch, customisable in length, initials, and stitching colour. For a completely bespoke experience, the Casati Milano atelier creates made-to-measure straps with personally selected leathers.

A handcrafted quality leather strap, if properly maintained, lasts 3–5 years depending on intensity of use and humidity exposure. Natural leathers, particularly vegetable-tanned alligator and calf, develop patina over time, improving tactile character. Moisture, perspiration, and thermal variation accelerate ageing. We recommend rotating between two straps to extend the life of each, and regularly clean with a soft damp cloth. Milano Straps guarantees 18 months on all handcrafted Casati straps.
