The AcuRite 24-inch Indoor or Outdoor Clock features a built-in temperature sensor and humidity sensor (hygrometer) that allows you to see your backyard, garden, or patio conditions at a glance. A quartz crystal (clock mechanism) movement provides reliable, accurate timekeeping, and the large, elegant Arabic numerals are easy to read from a distance. Thanks to this decorative, large wall clock's durable, weather-resistant construction, it's suitable for indoor or outdoor use, such as a kitchen clock, bedroom clock, or farmhouse wall clock. An attractive, hand-painted, weathered finish makes this analog clock and thermometer/hygrometer combination the perfect decorative accent for your home, deck, or patio. This big wall clock requires one (1) AA battery (not included) and comes with a one-year limited warranty.
