Launched as the inaugural execution in the exclusive Octo Roma Naturalia collection, this 44mm timepiece marries a sandblasted titanium case with black DLC treatment to a dramatic central band of polished black onyx-sourced and meticulously shaped from a single block of stone over months of artisanal labour. Its bezel gleams with baguette-cut black onyx, framing a skeletonized dial where the in-house BVL 206 manual-winding flying tourbillon movement reveals itself through intricate bridges and stone-filled negative space, delivering a 64-hour power reserve and mesmerizing legibility despite its open worked architecture. A black alligator strap with DLC-treated titanium buckle completes the bold, monochromatic presence. What elevates this reference to true rarity is its position within Bulgari's pioneering Maestria bespoke program-introduced alongside the Naturalia line to offer clients unprecedented personalization via a dedicated app in select boutiques. While the collection allows up to 30 variations across stones (onyx, malachite, lapis lazuli), case metals, settings, and engravings, the specific reference 103487 configuration represents one of the original demonstration pieces that debuted the concept. These highly individualized creations are produced on-demand for discerning clients, never in large series, making each example-including this foundational onyx iteration-exceptionally scarce and personal. In an era of mass-produced luxury, the Octo Roma Naturalia Onyx 103487 embodies exclusivity: a fusion of Roman-inspired geometry, technical horology, and the singular beauty of natural stone that few will ever possess.
