Brand history

From the earliest workshop pieces to today's Astronomia, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Jacob Arabo established Jacob & Co. in 1986, working from United States at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Jacob & Co. calibre produced today.
