Based on altimeters from WWII aircraft, with its stout brass screws and rugged shape, this clock brings fighter pilot precision to the desktop. Made of cast, machined aluminum with brass accents, its authentic dial houses the remnants of a subdial that marked altitude per thousand feet, while the main hands marked altitude per ten and hundred feet. The black clock face, which is framed with a brass rim, measures 3" in diameter. The clock casing measures 5-1/2" high x 4-1/2" wide x 4" deep. (Item #2558)
