The Heritage

The Octo Finissimo Automatic Titanium features a 40.00 mm brushed titanium case designed by Gérald Genta in 2012. This model combines eight-sided geometry with integrated bracelet architecture. Milano Straps offers custom strap solutions tailored to the octagonal case attachments using premium materials such as Mississippi Alligator or Barenia leather.
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 to the Bulgari Octo 102973?

No, the bracelet is integrated into the case. There are no traditional lugs where you can attach a strap. I've seen owners attempt workarounds—it doesn't work, and risks damaging the watch. If you want to change it, I craft a custom strap in-house, shaped to the exact geometry of your case.

How does the custom strap service work for the Octo?

You book an appointment with us at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from your case, study the original attachments, and handcraft the terminal to fit. There's no approximation—every detail adapts to the millimetre. The strap takes shape at my bench, right in front of you.

Which leather would I recommend for the Bulgari Octo 102973?

I favour Mississippi Alligator for contrast: midnight blue echoes the geometric radicalism of the case without competing. For fluidity, Barenia Étoupe speaks to the brushed titanium, almost an extension of it. The Octo is sporty yet demanding—I choose leathers that match its character, never ones that shrink beneath it.

How long does a well-made strap last?

It depends on use and care. Leather built to proper standards bears the weight of years—Barenia patinas, Alligator holds its structure. With reasonable maintenance (no prolonged soaking, balm occasionally), I've seen straps last 5, 6, 7 years without compromise. Leather ages with dignity—that's what I chase.

Why does the Octo demand a custom-made strap?

Because Gérald Genta designed an octagonal case where every element speaks to the rest. The integrated bracelet isn't accessory, it's part of the sculpture. A mass-produced strap would shatter that coherence. In the atelier, I ensure the terminal disappears, that the leather continues the watch's geometric conversation. It's respect for the object, and for who wears it.

The next step

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