Frequently asked questions

Can a standard strap be fitted to the Zenith Defy Skyline 03.9500.3600/01.I001?

No, the bracelet is integrated directly into the case with a proprietary attachment. A standard strap will not fit. For this reason, I offer a bespoke solution: I craft the strap directly on your watch, in the atelier.

How does the bespoke strap service work for this model?

We work exclusively at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from the case, study the geometry of the attachment zone, and create a strap that respects the original dodecagonal curves. It is not a standard operation: every detail is hand-crafted.

Which leather do I recommend for the Defy Skyline?

I prefer Mississippi Alligator or aged Barenia. This watch has a sporting yet elegant soul, and a noble leather can speak to the steel and case geometry without betraying that character. Metallic tones in Swift work well if you want something more contemporary.

How long does a well-made strap last?

With proper care, between 7 and 10 years of daily wear. Noble leather ages with dignity, develops patina, tells the story of time. The secret is to dry it after perspiration and keep it away from direct heat. Leather lives: the more you wear it, the more it breathes.

Why does the Defy Skyline's dodecagonal geometry require a bespoke strap?

Every facet of the case speaks to light according to precise proportions. A generic attachment would break this balance. When I craft the strap in the atelier, I study that curve millimetre by millimetre, and the result is an architectural continuity that the Defy deserves.

The next step

The right strap isn't chosen. It is built, together.
