The Heritage

The Bulgari Octo Finissimo Automatic Titanium features an octagonal case in titanium with grey-blue dial, launched in 2012. The integrated bracelet follows the watch's distinctive eight-sided geometry. Movement: automatic caliber. Diameter: 42 mm. Lug width: standard integration with octagonal case design. Part of the Octo collection, representing contemporary Italian design in the sport-elegant category.
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 103170?

No, the bracelet is integrated into the case. The attachment is not standard—a traditional strap won't fit. To switch to a strap, I craft it entirely bespoke in the atelier, shaping the attachment to match the precise geometry of your case.

How does the bespoke strap work for the Octo?

Visit <a href="/pages/casati-booking">Casati Milano</a> by appointment only. I take measurements directly from your case, accounting for the eight angles and the incline of the lugs. Each attachment is built millimetre-perfect for your specific case.

Which leather do you recommend for this model?

I prefer Mississippi Alligator or premium Barenia. The Octo is sporty yet elegant, with a titanium case that speaks of modernity. These leathers maintain a handcrafted soul without clashing with the case's contemporary geometry.

How long does a well-made strap last?

With proper care, 8–12 years of daily wear. The leather ages beautifully, developing a patina that tells time's story. Occasional cleaning and conditioning keep it supple and protected.

Why does the Octo have an integrated bracelet?

It's a deliberate architectural choice. Bulgari designed the case as a unified geometric block, where every element dialogues with the eight sides. The integrated bracelet is an extension of the form, not an accessory. Changing it demands respect for this design intent.

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.
