The silver numerals show up well against the black background for clear view. Because it has all three hands and displays hourly increments, this clock will give you an accurate read on time down to the second so you do not need to second-guess yourself. The simple design offers quick and easy installation. All you have to do is insert a single AA battery (not included) and the back slot makes it easy to hang. A thermometer and hygrometer are both included so the clock can measure temperature (Degree Celsius) and humidity (%). Add a nice touch to your room with a clock that's both practical and stylish.
