Actor Antonio Banderas spotted wearing a Bulgari

Antonio Banderas was recently spotted wearing the Bulgari Octo Finissimo in stainless steel, reference 103011 — a watch that rewards the informed eye far more than a casual glance. On the wrist, it reads as understated geometry; in hand, it represents one of the most technically ambitious thin-watch achievements of the past decade.

The Bulgari Octo Finissimo Ref. 103011 is built around the in-house BVL 138 automatic calibre, which measures just 2.23mm in thickness. Bulgari engineered this by integrating the rotor into the movement plate rather than stacking it on top — a construction that allows the complete watch to reach a total case thickness of only 5.15mm. Despite that extraordinary thinness, the movement retains a competitive 60-hour power reserve, delivered through a single barrel. The 40mm stainless steel case features the signature octagonal bezel with eight bevelled sides, combining polished and satin surfaces for a sharp, architectural finish.

Since its introduction, the Octo Finissimo line has accumulated a string of world records for the thinnest watches in various categories. Bulgari held the record for the thinnest automatic watch outright when the steel model launched, and the Ref. 103011 specifically brought the record-breaking specification to a more accessible stainless steel configuration after the initial titanium references. Among collectors, this steel version has earned considerable respect: it wears the same movement as far pricier versions but carries an everyday durability that titanium cannot fully match.

Antonio Banderas — Oscar-nominated for Pain and Glory, globally recognized as Zorro and El Mariachi — has long demonstrated a preference for refined, design-forward timepieces. The Octo Finissimo is precisely the kind of watch that suits a figure who moves between European arthouse cinema and Hollywood productions: it is quietly exceptional rather than loudly expensive.

At a retail price of $15,000, the Bulgari Octo Finissimo Ref. 103011 sits at a considered entry point for ultra-thin horology at this level. On the grey market, demand remains solid, with prices tracking close to or slightly below retail depending on condition and papers — a sign of genuine collector interest rather than speculative fever.
