Strap for Horological Machine N°4 HM4 Razzle Dazzle

No. The bracelet is integrated into the titanium case: the lugs are proprietary and a commercial strap won't fit. I've learned to work with the unique geometry of this machine. At the atelier, I build the strap directly onto the case, measurement by measurement.

You bring the watch to the bench at <a href="/pages/casati-booking">Atelier Casati Milano</a>. I take the measurements in person, study the curve of the case, and build the strap specifically for those lugs. By appointment only: each piece is an exception, never a series.

I favour Mississippi Alligator or naturally aged Barenia. This watch breathes titanium and aerospace engineering: the leather must be sporty, understated, and age with character. I don't chase false softness. The leather must hold its own against what sits on your wrist.

Five to ten years, depending on use and how you care for it. Quality leather ages in a predictable way: colour evolves, creases become part of the story. If you clean it occasionally and let it breathe, the strap won't break. It dies beautifully.

Maximilian Büsser designed the case as if it were a single sculpture. The lugs aren't right angles: they follow the titanium's curve. Understanding them takes time at the bench, not measurements from a chart. I find it fascinating: every detail tells how this object was conceived.
