The BVL-100 is a manual-winding in-house caliber introduced by Bulgari in 2022. Measuring just 5.4mm in diameter, it is among the smallest mechanical movements produced. Unlike traditional designs, it has no external crown; winding is performed through a key-wound system integrated into the caseback, transmitting power to the mainspring via ratchet wheels. The movement powers Bulgari's Serpenti Misteriosi secret watches.
