Strap for Defy El Primero 21 Rose Gold / Diamond / Skeleton / Alligator

The lug width of the Zenith Defy 22.9000.9004/71.R585 is precisely 23mm. It is measured internally between the shoulders of the spring bar lugs, with a tolerance of ±0.5mm. This specific width is consistent with the 44mm case diameter and ensures correct visual proportions.

Alligator remains the natural aesthetic choice: the fine texture and visible quills harmonise with the warmth of satin rose gold. Shell cordovan represents a more durable alternative with evolving patina. For versatility, fine-grain calf in dark brown or taupe grey allows seasonal changes. Smooth calf is not recommended, as it appears excessively domestic on this precious case.

The strap is changed by removing the spring bar lugs using a dedicated tool (spring bar tool). Simply extract the pin from the internal spring, slide out the old strap and insert the new one, then reinsert the pin until it clicks securely. Milano Straps provides specific instructions and telephone support for this operation.
