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

The lug width of the Zenith Defy 22.9003.9004/72.R585 is 23mm. This is a model-specific measurement, not a standard size. To verify compatibility with a strap, measure precisely the distance between the inner extremities of the watch's lugs. The 23mm specification requires straps constructed to this exact measurement.

For the Defy, we recommend alligator leather in natural tones (ivory, taupe brown, dark brown), which enhances the transparent case in rose gold without visually competing with the skeletal movement. Vegetable-tanned calf leather represents an elegant alternative with authentic texture that develops character over time. For a contemporary approach, silk NATO or technical rubber straps interpret the chronograph's sporting nature.

Changing the strap on a watch with fixed lugs requires a proper spring bar tool inserted gently between the lug and strap. Press downward to compress the internal spring, extract the pin. Insert the new strap by aligning the lug through both terminal holes and press the pin until it clicks into place. For luxury timepieces like the Defy, we recommend this operation performed by a certified watchmaker to prevent damage to the precious case.

Yes, any strap manufactured with 23mm lugs is compatible with the Zenith Defy 22.9003.9004/72.R585. Many artisanal brands offer straps with this specification. On milanostraps.it you will find complete collections of 23mm straps in alligator, calf, shell cordovan and other premium materials, customisable in length, initials and stitching colour.

A high-quality leather strap (alligator, vegetable-tanned calf, shell cordovan) mounted on a Zenith Defy can last 3 to 7 years depending on use, exposure to moisture and sunlight, and maintenance. Vegetable-tanned leathers age with elegance, developing natural patina. Artisanal straps such as those from Casati Milano include an 18-month warranty and allow maintenance or replacement of worn components.
