When setting the time on an antique clock, you should move only the minute hand forward, stopping at each hour and half-hour to allow it to strike before advancing it to the next half-hour. If it has a quarter-hour chime , you should also pause at the quarter-hour points to allow the chime to complete its cycle.
New clocks with two winding holes should be set in the same manner as antique clocks. New clocks with three winding holes can be set by moving the minute hand backward to the correct time. The chime will automatically correct its cycle within an hour after you have set the clock. If you have a calendar or moon dial on your clock, advance it forward only.
