Bulgari 103431 Octo Finissimo Automatic SS Blue Dial

The Bulgari Octo Finissimo Automatic ref. 103431 is a masterclass in ultra‑thin haute horlogerie, housed in a satin‑polished stainless steel octagonal case measuring a mere 6.40 mm thick and 40 mm across. Powered by the in‑house BVL 138 automatic movement with a platinum micro‑rotor, this caliber delivers an impressive 60‑hour power reserve and is exquisitely finished with Côtes de Genève, beveled bridges, and circular graining. The striking blue lacquered sunburst dial, paired with a small seconds display, is both elegant and contemporary, enhancing the watch’s architectural presence. With a screw‑down crown set with a ceramic insert and a transparent caseback, the piece achieves a robust 100 m water resistance—an exceptional feat for such a slender profile. The integrated satin‑polished stainless steel bracelet continues the refined aesthetic seamlessly. Introduced as part of Bulgari’s ongoing evolution of the Octo Finissimo line, this reference underscores the brand’s record‑setting achievements in thinness while offering daily practicality. Its design and technical pedigree make it a standout for collectors who value both avant‑garde style and mechanical sophistication. Like New with Bulgari box and papers dated 2020.
