Frequently asked questions

What is the exact lug width of the Bulgari Octo 101964?

The lug width of the Bulgari Octo 101964 is 30 mm, measured from the internal shoulder of one lug to the other. This specification is unique to this model and must be verified with a digital calliper before purchasing an aftermarket strap to ensure complete compatibility.

Which strap do you recommend for the Bulgari Octo 101964?

For the Bulgari Octo 101964, we recommend Niloticus alligator in vegetable tanning (black or dark brown), which amplifies the octagonal geometry of the case. Satin-finished box calf is the conservative choice; heavyweight canvas NATO represents functional contrast. The selection depends on daily use and aesthetic preference.

How do I change the strap on my Bulgari Octo 101964?

To change the strap, position the watch on a soft cushion. Locate the spring bar beneath the case. Using a dedicated tool or small screwdriver, gently press the bar's end to compress the internal spring, then extract the worn strap. Insert the new strap from the opposite side, ensuring the spring bar clicks firmly into the lug holes.

Can I use an aftermarket strap on my Octo 101964?

Yes. Any strap with a 30 mm lug width is compatible. However, we recommend purchasing straps from artisans who understand the proportions and geometry of the Octo: the strap must dialogue with the case, not compete. Milano Straps offers bespoke personalised solutions tailored to your specifications, ensuring aesthetic coherence.

How long does a leather strap last on the Bulgari Octo 101964?

A premium leather strap (alligator or calf) typically lasts 3–5 years with daily use, provided proper maintenance: avoid prolonged water exposure, dry immediately if wet, apply leather-specific balms every 6–8 months. Vegetable-tanned straps age visibly, developing patina and colour shifts that testify to time. An 18-month warranty covers manufacturing defects.

The next step

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

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
