Quartex Atomic Clock Movement


Our popular Atomic Clock Movement auto-synchronizes with the official U.S. time in Fort Collins, Colorado up to 5 times per day. Also known as radio controlled, these atomic movements are the most accurate clock movements on the market today. Auto-sets for DST assuring you have the correct time, every time. Use these atomic clock movements in your next project, or replace your old quartz motors with an updated clock movement that sets itself!

In order to ensure that your radio controlled clock motor receives the best signal strength, we do not recommend using this movement with a metal clock face. Operates in the Continental U.S. only in Pacific, Mountain, Central and Eastern time zones. Use #140547 hanger to hang your clock quickly and efficiently.
