The Heritage

The Octo represents one of Bulgari's contemporary collections characterized by the octagonal geometric design. The timepiece mounts the BVL 138 caliber which provides hour, minute and small seconds indication. Reference 103564 maintains the distinctive proportions of the Octo line with a case featuring marked architectural lines.
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 a standard strap be fitted to the Bulgari Octo 103564?

No, not a strap manufactured according to universal parameters. The Octo 103564 features a proprietary integrated lug system that forms part of the case design. The correct solution is a bespoke strap, constructed specifically for your watch during a consultation at <a href="/pages/casati-booking">Casati Milano</a>, where the exact lug dimensions will be measured and a strap crafted to integrate harmoniously with the case.

How does the bespoke strap manufacturing process work for this model?

During your session at <a href="/pages/casati-booking">Casati Milano</a>, the atelier measures the precise dimensions of the integrated lugs, their angle and depth. You then select the leather, buckle type and finishes together with the craftsman. The strap is subsequently constructed bespoke for your watch, ensuring perfect alignment with the case geometry and superior wearing comfort.

Which leather type best suits the character of the Bulgari Octo 103564?

Leathers with clean aesthetics and discrete, structured grain work ideally: alligator, crocodile, or aged calf that develops natural patina over time. We advise against excessively decorative textures – the octagonal geometry of the case requires no additional visual elements. A vegetable-tanned leather strap finished by hand with saddle stitch perfectly reflects the constructive precision of the watch.

How long does a quality strap made by Casati Milano last?

A strap constructed according to the artisanal criteria of <a href="/pages/casati-booking">Casati Milano</a>, with superior leather and carefully selected finishes, lasts years of daily wear. The leather develops patina and character over time, narrating the story of your wrist. With basic maintenance – avoiding excessive moisture and creasing – it maintains structural and aesthetic integrity for a decade or longer.

Is the BVL 138 movement in the Bulgari Octo 103564 reliable for daily use?

Absolutely. The BVL 138 calibre is Bulgari's in-house movement, designed specifically for this octagonal case with hours-minutes-small seconds configuration. It is constructed to Swiss watchmaking standards and is entirely suitable for continuous daily wear, offering reliability and precision over time.
