Bulgari Octo Finissimo reference 103527 puts the line's architectural case in full ceramic with a skeletonized dial. The 40mm square case and integrated ceramic bracelet keep the profile lean and graphic, and the open dial adds depth without disrupting the geometry. A manual movement powers the chronograph, power reserve, and additional functions. At 5.3mm thick, it wears with the flat, precise feel expected from the Finissimo.
