The Timex Perpetual Calendar watch automatically keeps track of the number of days in each month. Workers at the Timex factory preset the watch to the correct date, including the month and year. However, if the date ever slips out of the correct adjustment, it is easy to reset the perpetual calendar.

Pull the small knob on the right side of the watch, known as the crown, away from the watch face until you hear one "click."

Turn the crown to adjust the day until the watch displays the correct day and date.

Push the crown back so that it is flush with the watch. You have finished resetting the perpetual calendar on your Timex watch.
