FAQ

What is the lug width of the Zenith Revival 10.A3818.400/21.C105?

The Zenith Revival 10.A3818.400/21.C105 features a 20mm lug width, a precise measurement that reflects the balanced proportions of the 37mm case. To verify compatibility, measure the external distance between the two attachment pins with a digital caliper, positioning it perpendicular to the lug.

Which strap is best suited for the Zenith Revival forged carbon?

Black or grey Nile crocodile amplifies the technical character of the carbon fiber case, creating elegant contrast between geometric order and organic leather texture. Vegetable-tanned cognac calf represents the most versatile choice, introducing warmth without compromising sophistication. For extreme sports use, vulcanized rubber straps offer maximum practicality.

How do I change the strap on my Zenith Revival correctly?

Use a dedicated spring bar tool to remove the pins, pushing inward to release the tension spring. Remove the old strap, insert the new strap's pins into the case attachments, ensuring the spring is correctly positioned. Press until you feel the locking click. Avoid applying excessive force that could damage the pins.

Can I use third-party aftermarket straps on my Revival 10.A3818.400/21.C105?

Yes, provided they respect the 20mm width and the lug depth is compatible with the thickness of your chosen material. High-quality artisanal straps are fully compatible and offer superior customization compared to OEM options. Always verify precise dimensions before purchase.

How long does a leather strap last on a daily-worn watch?

A professional-quality leather strap with vegetable tanning and hand-executed stitching maintains structural and aesthetic integrity for 3–5 years under normal daily-use conditions. Wear frequency depends on exposure to sweat, moisture, and mechanical stress. The 18-month warranty offered by Casati Milano covers manufacturing defects, while periodic maintenance extends the strap's useful life.
