Strap for Big Bang 45 Red Gold / Black

No. The bracelet is integrated directly into the case: there are no standard lugs to attach a conventional strap. The attachment system is Hublot's proprietary design, with a patented geometry that rules out off-the-shelf solutions. The only option is a bespoke strap, built from the actual case upwards.

I work exclusively by appointment at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15, Milan. I take measurements directly from the case at the bench: every angle, every curve of the red gold profile. No templates, no estimates from a photograph — the strap is made on the watch, not on a datasheet.

For this red gold Big Bang, I choose Mississippi Alligator. The pronounced grain holds its own against the case's bold architecture, and a dark cognac or bordeaux shade works naturally with the warmth of the gold. French Barenia is a solid alternative for those who prefer something more understated: it ages well and develops a precise character over time.

A properly worked alligator strap easily lasts five to eight years of regular wear — sometimes longer. Care is straightforward: keep it away from prolonged exposure to water and let it breathe between uses. Quality leather does not deteriorate; it transforms. The marks of time tell you something about the person who wore it.

The six H-shaped bolts and the patented integrated attachment system are not merely decorative: they govern every millimetre of the transition between case and strap. I have seen many attempts using pre-made templates — the result always lets the watch down. Here, every attachment must be hand-modelled on the actual case, respecting the multilayer geometry Hublot has engineered. It takes time, but it is the only way to do it properly.
