The Octo 103889, seen from the bench

The Bulgari Octo Finissimo Chronograph GMT Automatic features an eight-sided titanium case with integrated bracelet, representing a synthesis of Roman architectural geometry and contemporary design. The octagonal form and proprietary lug attachment require specialized craftsmanship to ensure proper strap integration while maintaining the watch's geometric integrity.

Frequently asked questions

Can I fit a standard strap on the Bulgari Octo 103889?

No. The bracelet is integrated into the case with a proprietary Bulgari architectural attachment. A standard strap won't fit. That's why I craft bespoke straps directly in the atelier, modelled to the specific geometry of this watch.

How does the bespoke strap process work for the Octo?

You come to <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your case, study the angles and lugs millimetre by millimetre, then handcraft the strap to an individual casting. It's not an adaptation—it's an extension of the case itself.

Which leather do you recommend for the Octo 103889?

I prefer Mississippi Alligator for this model. The Octo is sportive and geometric: alligator has a defined grain that speaks well to the eight sides of the case, ages with character, and holds its structure over time. Barenia invecchiata is the choice if you want something softer and vintage from day one.

How long does a well-made strap last?

With noble leather and careful craftsmanship, expect 4–6 years of regular wear. It depends on you: sun, sweat and chlorine speed things up. Leather ages anyway, but good leather does it elegantly. Condition it with neutral wax now and then, and you'll live that strap as part of your watch's story.

What makes the Octo so different from other Bulgari watches?

The Octo was born from pure geometric vision: eight sides echoing Roman Colosseum architecture, but read through a contemporary lens. Case, bezel and bracelet are a single titanium sculpture—nothing is arbitrary. Bulgari designed it as an integrated form, not as watch plus bracelet. That's why changing the strap means respecting that logic.
