FAQ

What is the lug width of the Zenith Defy 95.9002.9004/78.R590?

The Zenith Defy 95.9002.9004/78.R590 features a lug width of 23mm, a rare and elegant specification requiring dedicated straps. Accurate measurement is essential: position a digital calliper between the two lugs and verify the exact internal distance.

What is the best strap for the Zenith Defy 95.9002.9004/78.R590?

Alligator leather in anthracite tones represents the ideal choice: fine grain mirrors the geometric rigour of the titanium case, creating extraordinary aesthetic coherence. For sporting versatility, pearl-grey NATO or matte FKM rubber maintain the model's minimalist integrity.

How do you change the strap on a Zenith Defy 95.9002.9004/78.R590?

Use a dedicated spring bar removal tool. Position on one lug side, gently press the spring and extract the bar. Repeat on the opposite side, then align the new strap's attachment points and reposition the pins until mechanical lockdown is audible.

Does the Zenith Defy 95.9002.9004/78.R590 accept aftermarket straps?

Yes. Built with standard spring bar lugs, the Zenith Defy 95.9002.9004/78.R590 is fully compatible with any 23mm artisanal strap. Milano Straps offers complete collections dedicated to this lug width, customizable in leather, initials and stitching thread.

What is the lifespan of a natural leather strap on a Zenith Defy 95.9002.9004/78.R590?

A naturally tanned leather strap, worn daily, has an average lifespan of 4-6 years with routine maintenance. Vegetable-tanned leather ages nobly, developing unique patina. On technical models like the Defy, we recommend rotation with rubber alternatives to preserve leather in humid climates.
