The Legacy Machines 07.TR.BU, seen from the bench

The Legacy Machine 07 represents MB&F's interpretation of the traditional perpetual calendar. It features the LM Perpetual calibre, which displays hours, minutes, date, day, month, leap year and power reserve. The 07.TR.BU reference showcases the Swiss brand's distinctive three-dimensional construction.

Frequently asked questions

Can I fit a standard strap on the MB&F Legacy Machines 07.TR.BU?

No. The bracelet is integrated into the case and the lugs are not standard. A commercial strap won't attach. If you want to change it, the only way is to have a bespoke strap built directly to the unique geometry of your case.

How does the bespoke strap work for this model?

We work at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your case, study the lugs millimetre by millimetre, and we hand-model the strap so it integrates perfectly with the zirconium. Nothing standard, everything built for your watch.

Which leather do I recommend for the Legacy Machines 07?

Mississippi alligator. This model has a sculptural, sporty architecture: the sharp grain of alligator dialogues with the geometry of the zirconium case, creating formal contrast that speaks to the watch's visionary character. If you want something that ages with grace, choose Barenia instead.

How long does a well-made strap last?

A strap built with craftsmanship lasts 8–12 years of daily wear, depending on how you treat it. Leather ages, develops patina, shifts colour. That's not wear: it's the story the hide tells. With moderate care and occasional cleaning, the strap follows you for years.

Why does the Legacy Machines 07 demand a strap thought differently?

Because the zirconium case and suspended movement represent pure architecture. A generic strap would betray that coherence. Büsser's mastery demands that every element at the wrist speaks the same language: technical, precise, uncompromising.

The next step

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