Although it has a slightly smaller diameter, the specs inside are more powerful than ever. Let’s dive in!

Bulgari Octo Finissimo 40mm Review The Original Legend of Thinness

Looking back at the classic Ref. 102711, the 40mm size is what made Bulgari a leader in the Ultra-thin Luxury Watch Comparison world. Featuring an incredible case thickness of just 5.15 mm and powered by the Calibre BVL 138 (only 2.23 mm thick) with a 60-hour power reserve, this model became an icon. Priced around THB 500,000, it offered a bold, architectural Roman look for those with standard wrist sizes.
