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 a leather strap be fitted to the Bulgari Octo 103389?
No, not a standard strap with straight bars. The integrated lug is part of the octagonal geometry of the case. A leather strap is created only bespoke, constructed specifically for your watch by <a href="/pages/casati-booking">Casati Milano</a>, with attachment rings tailored to integrate seamlessly into the case flanks.
How does the bespoke strap work for this model?
Casati Milano takes dimensional readings directly from your watch: tracing the lug contours, measuring the depth and inclination of the attachments. The strap is then constructed in the atelier with personalised rings, ensuring the leather integrates into the octagonal geometry without visual interruption.
Which leather suits the character of the Bulgari Octo 103389?
Vegetable-tanned leather with pronounced grain complements the faceted case surface; smooth, polished leather accentuates the design's linear purity. Dark tones (black, brown, burgundy) underscore the authority of rose gold, whilst warmer shades enhance its luminosity. The leather should enhance the geometry, not compete with it.
How long does a bespoke strap made by Casati Milano last?
An artisanal strap crafted from quality vegetable-tanned leather with sartorial construction lasts years with proper care. Longevity depends on frequency of wear, leather type, and periodic maintenance. Casati Milano provides specific care instructions for each strap made.
Why does the Octo 103389 require such a specialised approach?
The Bulgari Octo is a statement of pure geometry: its eight sides flow from case to lugs in visual continuity. A conventional strap would interrupt that line. Bespoke, your strap becomes an extension of the case, not an accessory, preserving the watch's design integrity.
