The Heritage

The Octo Finissimo Automatic Tadao Ando features an octagonal titanium case measuring 40mm, representing Bulgari's geometric revolution in watchmaking. Powered by an automatic movement, this ultra-flat timepiece merges Roman precision with Swiss horological technique. The watch is designed for integration with a custom strap, requiring specialized lug attachment tailored to its architectural proportions.
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 a standard strap be fitted to the Bulgari Octo 103245?

No, the bracelet is integrated into the case: a standard strap will not attach. The Octo is built with a proprietary architecture that requires a bespoke solution. I craft the strap directly on your case, modelling the attachment according to the original proportions of Bulgari's design.

How does the bespoke strap process work for the Octo?

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, via XX Settembre 15. I take all measurements directly from your case, observing the geometry of the transition between the titanium and the attachment point. This is the only way to guarantee visual continuity faithful to Bulgari's original intent.

Which leather do you recommend for this model?

I prefer Mississippi Alligator for those seeking formal elegance and geometric clarity: the fine grain dialogues perfectly with the sharp angles of the titanium case. For those who love a richer, more natural patina, Barenia is the choice: it ages nobly and gains character over time, exactly as an object of this solidity deserves.

How long does a well-made strap last?

With proper care, 8–10 years of daily wear without issue. Quality leather ages rather than deteriorates: it develops a patina that tells the story of time at the wrist. I recommend keeping the strap dry after water exposure and applying a natural balm once or twice a year.

Why does the Octo require such a specific approach?

The octagonal form is not merely aesthetic: it is an architecture that lives by millimetre proportions. The transition from sculptural titanium to strap must be invisible, seamless. A rushed attachment betrays Bulgari's work. With Casati we build the strap not as an accessory, but as a natural extension of the original geometry.

The next step

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