Frequently asked questions

Can you fit a standard strap on the Apple Watch MJYN2LL?

No, the bracelet is integrated into the case and the attachment is proprietary Apple: no commercial strap will fit. In the atelier I build your strap bespoke, directly onto the geometry of the case. It's the only way to have something that works.

How does the bespoke strap process work for this model?

I expect you at <a href="/pages/casati-booking">Atelier Casati Milano</a>, by appointment only. I take measurements directly from the case, study the patented attachment, and handcraft the millimetric connector. Everything demands absolute precision.

Which leather do you recommend for the Apple Watch MJYN2LL?

Mississippi white alligator. It mirrors the ceramic's luminosity and keeps that minimalist clarity the watch embodies. If you prefer contrast, carbon black Swift is architectural. It depends on how you see it on your wrist.

How long does a well-made strap last?

With daily care, quality leather ages well for 5-7 years. The patina that forms is part of its story — the hide becomes softer and more yours. If you neglect it, it lasts less. If you love it, it lasts.

Why does the ceramic require such precise work in the atelier?

Technical ceramic is four times harder than steel, yet fragile under concentrated stress. The Apple patented attachment has micrometric tolerances. A handcrafted connector that understands this geometry protects the watch and ensures fluidity. It's not a detail, it's the foundation.

The next step

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