Strap for Defy Extreme Double Tourbillon Yoshida White Gold / Rose Gold

The lug width of the Zenith Defy Extreme with reference 87.9100.9020 /22.l200 is 23 millimetres. This dimension represents the distance between the inner lugs of the case and is critical for strap compatibility. It should be measured precisely using a digital calliper positioned perpendicularly between the lug pins.

For the Defy Extreme in white and rose gold, we recommend alligator in havana tones or shell cordovan in deep burgundy. Both materials complement the precious metals elegantly and develop a patina that matures with the watch over time. For sportier wear, a silk-cotton NATO in black with a deployante maintains technical coherence without sacrificing robustness.

To change the strap, first remove the deployante (if fitted) by sliding out its centre pin. Subsequently, use a spring bar tool or small screwdriver to extract the pins securing the strap to the lugs. Once removed, slide off the old strap and position the new one by aligning the holes with the lugs. Reinsert the pins precisely, ensuring the strap is centred and moves freely.

Any strap with a lug width of 23 millimetres is compatible with the Defy Extreme. Milanostraps.it offers a comprehensive collection of 23mm straps in premium materials—alligator, shell cordovan, vegetable-tanned calf, and technical solutions—all engineered to fit precisely within the case's lug-to-lug distance. Customisation includes colour selection, length, initials, and stitching thread choice.

A high-quality leather strap, crafted in alligator or shell cordovan with artisanal finishing, has an average lifespan of 3 to 5 years with moderate daily wear. Longevity depends on UV exposure, humidity, frequency of use, and maintenance practices. Premium alligator with vegetable tanning can reach 6 to 7 years. Casati Milano provides an 18-month warranty on all bespoke straps and offers specialised repair services.
