The Heritage

The Bulgari Octo 105053 features an octagonal pink gold case with integrated faceted bracelet, embodying Roman geometry and contemporary engineering. This automatic timepiece represents an iconic design challenge in modern haute horlogerie. Customization through Atelier Casati Milano ensures bespoke strap craftsmanship tailored to the watch's distinctive architectural geometry.
Made to Measure

The strap for this watch is made to measure

On the Bulgari Octo the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

Can you fit a standard strap on the Bulgari Octo 105053?

No, the bracelet is integrated into the case. The attachment is not standard: a regular strap simply won't fit. For those wanting a strap, I craft a bespoke piece directly on your watch, studying the unique geometry of the case.

How does a bespoke strap work for this model?

We work exclusively at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your case, study the proprietary lugs and handstitch the strap to fit perfectly. It's not a quick job, but it's the only way to respect the watch.

Which leather do you recommend for the Octo?

I prefer Mississippi Alligator. The Octo is a watch built on architecture, on decisive geometry: the leather must have that same structural precision. Alligator has that natural hardness, that ordered grain that speaks well with the eight facets of the case. It ages with character, without deteriorating.

How long does a well-made strap last?

It depends on how you wear it. A quality leather strap, worn regularly and cared for, lasts 5-8 years without issue. The best leather ages elegantly: it develops patina, softens. If you clean it occasionally and condition it once a year, the strap travels with you.

Why does the Octo have an integrated bracelet?

It's an architectural choice. Bulgari wanted the case and bracelet to breathe as one structure. The eight facets continue across the faceted links. It's not convenient for frequent strap changes, but it's honest to the design: if you choose the Octo, you choose that geometric coherence.

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.
