Bulgari caliber BVL 138 Hours, Minutes, Small Seconds

The Heritage

The Octo represents Bulgari's high-end watchmaking collection characterized by the distinctive octagonal case. The model is equipped with the in-house caliber BVL 138 with hours, minutes and small seconds indication. The construction features an angular geometry combining flat and faceted surfaces according to the characteristic design of the line.
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 I fit a standard strap on a Bulgari Octo 103672?

No, the bracelet is integrated into the octagonal case. A traditional strap with standard lugs won't attach. That's why we step in at the atelier: I craft the strap directly on your watch, hand-shaping the attachment to follow the titanium's geometry.

How does the bespoke strap process work for the Octo?

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from the watch, read the octagonal spaces of the case, and hand-craft the attachment. It's not catalogue work.

Which leather do you recommend for this model?

I prefer vegetable-tanned Tuscan leather. The Octo is sporty and geometric — it won't accept aesthetic compromise. A vegetable-tanned hide that ages well, developing patina, speaks to the purity of the titanium without competing. It's the choice that honours Bulgari's Roman architecture.

How long does a well-made strap last?

Five to seven years with balanced use. It depends on how you treat it: avoid excessive moisture, dry it if wet, don't crease it in the same spot repeatedly. Vegetable leather ages quickly but holds up — it develops character a new strap never possesses.

Why do the eight facets of the case require a bespoke strap?

Because that geometry isn't decorative — it's structural. Put a generic strap on an Octo and you break the dialogue between the case and what embraces it. In the atelier we craft the attachment following those sides, so the strap becomes part of that vision, not a compromise.

The next step

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