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 a matte black finish and 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 #2557)
