The Oregon Scientific RM383P Self Setting Atomic Projection clock keeps precise time and projects the time in large easy-to-read numbers onto ceilings or walls. The projection feature offers a unique way to read time in lowlight conditions by casting soft glowing red numbers on a wall, ceiling, or just about any flat surface. The self-setting Atomic clock means you’ll always have precise time and never need to adjust the clock for Daylight Saving Time.
