Conquest Heritage L1.649.4.02.2— lug 19mm

The lug width is 19 millimetres. This measurement represents the distance between the two suspension pins on the case. It is essential to verify this measurement precisely before purchasing a replacement strap, as it is not compatible with standard 18mm or 20mm solutions.

The choice depends on your intended use. For formal elegance, we recommend cognac brown or black alligator. For a sporty-elegant profile, vegetable-tanned calf leather in natural tones is ideal. For everyday wear and absolute water resistance, dark grey FKM rubber offers practicality and visual restraint.

Use a spring bar tool to gently lift the suspension pins. The first pin is extracted by rotating the tool towards the case; the second is removed by pulling the old strap and inserting the new one. The operation requires no technical expertise, or you may entrust it to a specialist atelier such as Casati Milano.
