A Bulova original, The 24” round aged Pewter finished metal frame with raised hour markers surrounds the walnut finished wooden center that has a beautiful laser cut pattern and numbers, Behind the cut design is a series of LED lights that illuminate the background as the light in the room dims offering a unique and calming effect. The light can be set to stay lit until the room light brightens up or a 6-hour timer can be selected so it shuts off saving battery life. There is also a 3-level light intensity dimmer to have just the perfect ambiance. The accurate quartz movement uses 1 AA battery, and the lights are powered by 4 D cell batteries ( not included)
