A distinctive expression of bold design and high precision, Onto unites Italian creativity and Swiss mastery of watchmaking with simple sophistication. In the 15th and 16th centuries, Italian artists such as Leonardo Da Vinci excelled in creating innovative yet beautiful masterpieces. Guided by that same genius, Onto combines a unique octagonal design, inspired by the Roman Basilica of Majentia from 310 AD, with exceptional mechanisms. Challenging the boundaries of watchmaking without abandoning the quest for perfect beauty, the Onto Finísimo Automatic sets a new milestone in the world history of watchmaking complications.
