An architectural take on the modern dress watch, this Bulgari Octo Finissimo Extra Thin pairs the line's sharply faceted 40mm case and integrated yellow gold bracelet with a rich blue dial. The yellow gold execution gives the Octo's geometric profile added warmth without softening its crisp, technical character. Its automatic movement supports the model's defining slimness, held to just 6.4mm thick. On the wrist, it wears broad and linear yet remains impressively flat and refined.
