Frequently asked questions

Can I fit a standard strap on the MB&F Legacy Machines 05.WSL.WMA?

No, the bracelet is integrated into the case and the lug attachment is non-standard. A commercial strap won't fit. If you want to change it, the solution is to have a custom strap made directly on your watch at <a href="/pages/casati-booking">Atelier Casati Milano</a>.

How does the custom strap work for this model?

Bring the watch to the atelier. We work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from the case, study the integrated lugs, and build the strap calibrated to the millimetre for your specific piece.

Which leather do I recommend for the Legacy Machines 05?

I prefer Mississippi Alligator. This watch has an organic, almost sculptural architecture: leather with that natural structure speaks well to the case geometry. It's sporty yet elegant, and Alligator ages in a way that matches that personality.

How long does a well-made strap last?

With quality leather and proper care, 8–12 years of regular wear. It depends on how often you wear it and how you treat it. Leather evolves, it develops a patina, it tells the story of your habits. If you come back to the atelier now and then, I can check it and refresh it where needed.

Why does the MB&F Legacy Machines 05 require a bespoke approach?

The white gold case has non-conventional architecture, with organic curves and a three-dimensional movement in view. A generic strap doesn't respect this complexity. Made to measure, it becomes a coherent part of the object, not an afterthought.

The next step

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

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
