The Octo 103297 (aka: BGO40C3PSSXTAUTO), seen from the bench

The Octo Finissimo 100m is a stainless steel octagonal watch designed by Gérald Genta, featuring 110 geometric facets and an integrated segment bracelet. This contemporary horological architecture represents uncompromising engineering craftsmanship from Bulgari. Water-resistant to 100 meters, the black dial model combines geometric complexity with integrated bracelet design.

Frequently asked questions

Can I fit a standard strap on the Bulgari Octo 103297?

No, the bracelet is integrated into the case. There are no standard lugs to attach a strap. It's Bulgari's design choice: the octagonal geometry doesn't accommodate off-the-shelf solutions. I craft the strap directly on your case, shaped precisely to your wrist.

How does the bespoke strap work for the Octo?

We work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements straight from your watch: I study the case angles, the geometric attachment points, your wrist circumference. Each strap is built from that specific foundation.

Which leather do you recommend for this model?

I prefer Mississippi Alligator. The Octo is a conscious instrument of geometric architecture, elegant and deliberate: alligator brings natural structure that speaks to the case facets without fighting them. For those who want a lived-in patina, Barenia ages beautifully and tells time's story.

How long does a well-made strap last?

With thoughtful wear, at least 4–5 years. It depends on the leather chosen, sun exposure, and humidity. The real luxury is that good leather ages well: it doesn't degrade, it patinas. Simple care—no direct water, occasional conditioning once a year—keeps the strap sharp for years.

Why did Gérald Genta design the Octo as an octagon?

The octagon is pure geometry, visual rhythm that doesn't announce where it starts and stops. Genta wanted to break the habit of round. This 103297 in steel carries that philosophy into a sporty, urban form: eight lines that meet perfectly, a watch that knows exactly what it stands for.
