Aircraft Clock, 24 Hour, 8 Day Wakmann Model A-11-24 Lockheed The luminous markings have turnedHere is a fine specimen of a Swiss made 24 hour, 8 Day Aircraft Clock, manufactured by Wakmann, Model A 11 24 likely 1950 1960's vintage. The knob sets the time when pulled and rotated; otherwise the knob winds the clock when rotated clockwise. The clock works when wound and seems to keep time, but its accuracy has not been confirmed. It has an aluminum case measuring 2 3 8 inches square and the round clock face measures 2 1 4 inches diameter.
