Casio Quartz Watches - One Month Accuracy Results

Recently I found a bunch of inexpensive, analog, quartz watches at local Walmart stores and I decided to give them a try. Normally, I am more attracted to Casio's Wave Ceptor and G-Shock watches which often feature built-in atomic time receivers so that they're always set to the right time (right down to the second!). The automatic time adjustments make the watches extra convenient to use. But these watches were all so well made and were such good bargains that I decided to try them out. What amazing value! Each watch works incredibly well and far exceeds the accuracy that Casio promised (which was plus-or-minus 20 seconds per month).

In this video I give you the results of a 30-day accuracy test. At the start of the test I manually set each watch to the right time (according to an atomic time source). At the end of 30 days I recorded video of each watch ticking next to an iPhone running an app called Emerald Time. The app was showing a running display of the correct time, down to 1/10th of a second. I examined the still frames from those videos to determine how closely the watches were matched to atomic time and I reported the results. Needless to say, the results made me very satisfied with every one of these bargain watches.

If you want to go back and see how enthusiastic I was after just half of this one-month test was complete, here's the video I made at the 15-day mark. https://youtu.be/qqywfbngwNw

Watches featured in this video include two colors of the Casio Duro (or Marlin) MDV106, two versions of the MRW200H, two versions of the MRW210H, two versions of the FT500W and one each of the MTPS110, the MTD1079 and the MRWS310.
