Bulgari Octo Finissimo Automatic | Ref. 103077 | Black Ceramic | 40mm | BVL 138

Bulgari Octo Finissimo Automatic | Ref. 103077 | Full Black Ceramic | 40mm | BVL 138 | Thinnest Full Ceramic Watch with Mechanical Movement Ever Made

The Bulgari Octo Finissimo Automatic in full black sandblasted ceramic holds a distinction no other watch can claim — it is the thinnest full ceramic watch with a mechanical movement ever made. At just 5.50mm case-thin and powered by a manufacture caliber measuring only 2.23mm thick, this is an engineering achievement that redefined what ceramic could do in haute horlogerie. The result is a watch that wears with razor-sharp elegance and commands attention without a single gram of precious metal.

Why This Watch

Few watches can claim a world record and still wear like an everyday piece — the Octo Finissimo does both. The monochromatic all-ceramic execution gives it a stealth, tool-watch attitude that sits equally at home with a suit or a casual fit. The platinum microrotor, visible through the sapphire case back, is a finishing touch that rewards those who know what they're looking at. This is Bulgari at its most audacious.
