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).
