Bulgari Octo Finissimo Ultra COSC Watch
Bulgari regains the title of the world's thinnest watch with the Octo Finissimo Ultra COSC. At just 1.70mm thick, the timepiece doesn't break just one record, but with its COSC certification, it's also the thinnest chronometer-certified watch ever made. Its 40mm case masterfully houses a 170-component manually wound BVL 180 movement and features a tungsten carbide back for durability. The Bulgari Octo Finissimo Ultra COSC is limited to only 20 examples.
