Aviation Gifts: Our newest additional in our line of popular WW II metal altimeter clocks is our Altimeter Mantel or Shelf Clock. Whether you enjoy historical artifacts or have an interest in aviation this quality built clock is for you. The dial was reproduced from an actual World War II aircraft cockpit gauge. And, to keep the Altimeter Mantel Clock with chronological perspective, the clock hands are replicated from a 1940s era clock. The clock hands also produce a nice high contrast for quick and easy readability. The dial is covered with clear convex glass crystal, and it is surrounded by attractive nickel-plated brass knobs. Adding the iron base, thereby elevating the Altimeter Mantel Clock, helps to display this eye-catching piece on a mantel, table top, or shelf. The quartz movement needs a AA battery for clock use.
