NOTES: This is Bulova's first fully digital watch. It was introduced in the same year as the calendar watch (1932 Calendar Watch) and followed by the President with wandering seconds (1934 President), both of which also have a digital component. Additional designs for Bulova's fully digital watches can be viewed here: 1932 Jump Hour and 1932 White Prince.
