Keep track of time with the utmost precision while working in the garden, splashing in the pool, or barbecuing on the patio with this 18-inch outdoor atomic wall clock from La Crosse Technology. Radio-controlled by the national atomic clock in Colorado, the clock resets daily to the hour, minute, and second for continued accuracy. Additionally, the clock adjusts automatically for daylight savings time. 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, and take precautions against an icy walkway.

Surrounded by a sleek silver-painted plastic frame, the clock face features black 1-1/6-inch-high numbers for easy visibility. Elegant, black metal hands tick off the hours and minutes. For temperature and humidity readings, the clock face displays two small analog gauges. The hygrometer gauge measures from 0 to 100 percent relative humidity, while the temperature gauge gives readings for temperatures from -10 to +130 degrees Fahrenheit, or -30 to +60 degrees Celsius. On the backside of the clock, the user selects the appropriate US time zone; the clock accommodates Eastern, Central, Mountain, and Pacific times. A manual reset button is provided. To ensure accurate readings, hang the clock in a dry area out of direct sunlight. This clock requires the separate purchase of one AA battery for operation. A one-year limited warranty covers this item. The clock measures 18 inches wide by 2-1/5 inches deep by 18 inches high and weighs 6 pounds upon shipping.
