The Octo 103151, seen from the bench

The Bulgari Octo Finissimo Automatic Titanium/DLC/Green features an octagonal case in titanium with DLC coating and integrated bracelet, representing contemporary architectural geometry. This automatic movement timepiece combines titanium with rose gold for visual balance. The model requires custom strap attachment work due to its integrated design and distinctive octagonal architecture.

Frequently asked questions

Can I fit a standard strap to the Bulgari Octo 103151?

No, the bracelet is integrated into the case. There are no lug attachments — a conventional strap won't fit. To change the strap, I build everything bespoke directly on your case, measuring the exact proportions at the bench.

How does the bespoke strap work for this watch?

Come to the atelier. <a href="/pages/casati-booking">Casati Milano</a> is by appointment only — no waiting list, just availability you need to book. I take measurements from your case, we shape the attachment by hand, no forcing. The result is a strap that slides on and off as though it were original.

Which leather would you recommend for the Bulgari Octo 103151?

Mississippi Alligator. This watch has clean, sporty geometry — alligator leather keeps that architectural tension. The rose gold and titanium demand elegant yet robust texture, and alligator ages with dignity, developing a patina that speaks of real wear.

How long does a well-made strap last?

With proper use, five, six years. It depends on how often you wear it and how you treat it — protect it from water, dust, constant friction. When it ages, it ages well: the leather breathes, darkens, tells the story of time at your wrist. When that moment comes, I rebuild it.

Why does the Bulgari Octo have an integrated bracelet?

It's a design choice. The octagonal case and the fluid bracelet must speak as one — an architectural sculpture. If the lugs were separate, you'd lose that continuity. Bulgari chose formal coherence over convenience. I respect that choice, and translate it into straps that honour that promise.

The next step

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