Keep track of time with the utmost precision while working in the garden, splashing in the pool, or barbecuing on the patio with this classic, sophisticated atomic wall clock from La Crosse Technology. Large polyresin analog clock will add a warm and inviting feel to your home with its white-washed bronze metal frame and hammered design and delivers a rustic elegance to any space. This radio-controlled time piece receives a signal from the atomic clock in Fort Collins, Colorado for the highest level of precision. It measures 21 inches wide by 3.25 inches deep and operates with a High Torque time movement. With its easy to read 13.75-inch dial, this timekeeper allows you to see it from a distance. Select appropriate US time zone, as clock accommodates Eastern, Central, Mountain, and Pacific times or adjust with its manual set button. Equipped with a thermometer and a hygrometer, the clock also assesses and relates temperature and humidity levels to help users protect seedlings from frost, avoid over-watering finicky plants, or precautions against an icy walkway. Monitor ambient temperature, displaying in either Fahrenheit or Celsius and humidity to optimize comfort level. Hang it outdoors in a patio or gazebo, as it is protected from UV damage and weather resistant with a weather seal and gasket lined glass lens. To ensure accurate readings, hang the clock in a dry area out of direct sunlight. Add additional batteries in extra compartment to extend lifetime without replacing batteries up to 5 years.
