The Heritage

The Bulgari Octo Solotempo 38 Blue Bracelet features a distinctive octagonal stainless steel case of 38mm. This architectural design icon represents pure geometry and formal rigor. The model is part of Bulgari's Octo collection, combining haute horlogerie with Italian design audacity.
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 102105?

No, the bracelet is integrated into the case itself: the lugs are proprietary and a standard strap won't attach. If you want to change straps, I recommend <a href="/pages/casati-booking">Casati Milano</a>, where I create a bespoke leather solution built directly onto your case.

How does the bespoke strap process work for the Octo?

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15 in Milan. I take measurements directly from your case, read the original lugs millimetre by millimetre, and hand-craft the strap to integrate perfectly with the octagonal geometry.

Which leather do you choose for the Octo?

I prefer alligator for this model: its fine grain speaks to the clean surfaces of the case, and the leather's solidity supports the architectural character of the design. The Octo isn't fragile elegance—it's material rigour. Alligator announces that immediately.

How long does a well-made strap last?

With daily care, a strap in fine leather lasts between 5 and 10 years, depending on use and sun exposure. Alligator, kept away from excessive humidity, absorbs the years with dignity—natural creases tell the story of who wears it. An occasional pass with a soft brush keeps it right.

Why does the Octo demand such a specific handcrafted approach?

The Octo is a geometric manifesto: every angle of the octagonal case communicates with the strap. An integrated original bracelet is part of this watch's formal language. Only by physically reading the case and hand-working the leather bespoke can I create an alternative that doesn't betray the architectural precision that makes the Octo what it is.
