Many Bulova watches come with a special date display that moves with the watch to show the correct day of the month. Since the mechanism cannot know which month of the year it is, many Bulova watches need adjusting once a month. The date display advances from "1" to "31" regardless of the month. Wait until the second hand reaches the the "12" mark and pull the "Crown" dial on the side of the watch out as far as it will go.
