Zenith
Defy 95.9002.9004/78.M9000— lug 23mm

The lug width of the Zenith Defy 95.9002.9004/78.M9000 is 23mm. This measurement is taken by aligning a ruler against the inside wall of the spring bar from one side to the other. The 23mm dimension is proportioned to the 44mm case and ensures aesthetic balance of the strap on the wrist.

Alligator leather offers structured elegance with orderly grain that contrasts the aggressive lines of the titanium case. Calf leather introduces uniform texture and natural patina development over time. Heavy cotton NATO straps amplify the sport character, whilst structured rubber reinforces the technical and performance heritage of the collection. Material choice depends on usage context and desired aesthetic coherence.

The Zenith Defy 95.9002.9004/78.M9000 uses standard spring bars. Insert the removal tool into the lateral spaces of the spring bar, apply gentle pressure to retract it, then extract the lug. Repeat on the opposite side. To install the new strap, align the lug holes with the spring bars and push until you feel the locking click. If you lack the tool, consult a watch repair shop or contact Casati Milano for professional assistance.

Yes, any strap with a 23mm lug width is compatible with the Zenith Defy 95.9002.9004/78.M9000. High-quality artisanal aftermarket straps maintain the same technical functionality as original solutions, whilst offering opportunities for colour and material personalisation. Always verify that your strap is constructed for standard 23mm measurements to ensure correct fitment.

A quality leather strap (alligator or calf) subjected to regular wear maintains structure and aesthetics for 3-5 years, with gradual patina ageing. Longevity depends on exposure to moisture, perspiration and sunlight. With proper maintenance (annual leather conditioning), an artisanal strap can last beyond 7 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
