This large Air Station Wall Clock can display up to 4 different time zones while the middle dial has a sweeping second hand. The vintage style of the clock goes back to the WW II years when it was imperative to be aware of times in different locations. The large size of the clock, at 43 inches high, makes a striking impression. The clock case itself is crafted with iron sheet metal in a riveted steel case. The iron conduit and distressed painted finish provide for the aged look of the clock. Three “AA” batteries are needed for use.
