Strap for Big Bang Unico 45 Full Magic Gold

No. The bracelet is integrated into the case with proprietary attachments: a catalogue strap simply cannot be fitted — there is physically no way to do it. I build each strap to measure, working directly on the watch at the atelier.

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, at Via XX Settembre 15 in Milan. I bring the client to the bench, take measurements directly from the case, study the geometry of the attachments and build everything by hand. There is no template: every strap is made from scratch for that specific watch.

For a Big Bang in ceramic and Magic Gold, I go straight to alligator with a matte or semi-gloss finish. The natural grain of the reptile leather works well with the micro-polished surface of the ceramic, without undermining the bold character of the piece. I avoid soft, casual leathers — they simply do not hold up against the personality of this case.

With ordinary care — keeping it away from water, letting it breathe between wearings — a well-crafted alligator strap easily lasts five to seven years. Over time the leather settles, takes the shape of the wrist and improves. It is one of the few things that ages honestly.

Magic Gold is a patented alloy developed by Hublot, forged at 1000°C: it is the only gold that resists scratches, a property no other gold alloy has. This means the case holds its appearance over time, and the strap becomes the only element that shows the signs of daily life. I choose materials that age with dignity, because they will be the ones to tell the story of the years on the wrist.
