The Heritage
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.

Can you fit a standard strap on the Bulgari Octo 103137?
No, the bracelet is integrated directly into the case. The attachment does not follow standard lug conventions, so a commercial strap cannot be fitted. That's precisely why I work with <a href="/pages/casati-booking">Casati Milano</a>: I craft a bespoke strap, modelled to the specific geometry of your case.
How does the bespoke strap process work for this model?
It begins at <a href="/pages/casati-booking">Casati Milano</a>, strictly by appointment. I take measurements directly from your case, examine the integrated attachment, and design the strap so it fastens and sits in perfect harmony with the octagonal lines of the case. Pure craftsmanship, nothing more.
Which leather do you recommend for the Bulgari Octo 103137?
I favour Tuscan leather with vegetable tanning for this watch. The titanium is extremely light and sporty, and vegetable-tanned leather develops a natural, dignified patina—much like the case itself. If you want solidity and character, it's the right choice.
How long does a well-made strap last?
A quality leather strap easily lasts 5 to 7 years with ordinary care. Leather does not age poorly: it grows darker, softer, and tells the story of your wearing it. Once a year, apply a neutral oil, and avoid prolonged water exposure. After years of use, it remains a strap—not a memory.
Why does the Octo have an integrated bracelet in the case?
Gérald Genta designed the case as a complete geometric unit: eight faceted sides, precise proportions. Integrating the bracelet was a choice of formal purity, not convenience. For anyone wanting a strap, that's exactly why bespoke work makes sense: respect for the original vision of the case.
