Quartex® Atomic Clock Movement is rated out of 5 by 3.
Rated 5 out of 5 by Socorro from Pay attention to instructions I purchased this movement with high expectations. At first, there were some issues with reception, but I discovered that South Florida, where I live, is often out of range for the transmitter in Colorado. After resetting the movement a couple of times and placing the clock in an ideal position for reception, it synchronized with the transmitter and worked well until the change from Daylight Saving Time to Standard Time. Obviously, the signal is based on UTC and takes no account of whether or not your location is using Daylight Saving Time or Standard Time. The clock did not make the necessary correction until I changed the DST switch from Yes to No. The movement instantly made the correction by advancing the hands 11 hours. I recommend this item but with caveats. 1) Pay close attention to recommendations about placement. 2) Assure that the DST switch corresponds to the correct phase of the time change cycle. 3) If you live far from the signal, don't expect the clock to adjust outside the hours of 11PM - 4 AM local time. That said, I believe this movement will function as a highly accurate atomic clock.

Rated 5 out of 5 by Gary St from 0.23 in max thickness of the face. After largely ignoring a couple of my clocks, due to the time not being quite right, I finally installed this movement. It is great for the clocks all agree. The max thickness of the face this movement will handle is 0.23 in, as this is what I needed to sand it down to so the nut would seat. You cannot use the rubber washer at this thickness so I used hot glue to prevent the movement from shifting. I also purchased this from KLOCKIT directly as you get a large selection of hands to pick from, rather than the one hand set with Amazon.

Rated 5 out of 5 by Trailmaster Troy from It is great to be on time and not too early. The clock is just always right.
