Got mine on the 27th, and I thought it was busted. It didn't seem to sync at 3:10am and 5:10 am like the package said it would. What's more, the band was much too large for my wrist, so I wasn't wearing it at first. However, I went and got links removed anyhow, and figured I could set it manually if I couldn't get its atomic powers working.
I don't know if there's any actual science behind this assertion, but the dang thing actually seems to pick up a clearer signal when it's mounted to my wrist. Don't know if I'm acting as a human antenna, but it seems to pick up a signal no problem now. Also, I read the NIST website on radio controlled timepieces, and it offered some really valuable information for those of you having trouble.
First, I live in central Ohio, which is 1314.74 miles from Fort Collins, CO. (The origin of the WWVB radio signal for all of North America.) I cannot get any signal whatsoever during daylight hours. If you live east of Ohio, chances are, it's the same for you. Don't even try to set it during the day. The sun somehow interferes with the radio signal. Second, follow the instructions to set it manually operate using the WWVB signal. When mine was set to auto-scan, it either picked up the signal from Japan, or misinterpreted the WWVB signal for the Japanese one, and my watch was quite a few hours off. Finally, the radio is very sensitive to interference. If you have this sitting within a few feet of a fluorescent lamp or an AC adapter, it probably won't get a signal. Apparently, the extremely low frequency that NIST uses for the WWVB signal is great at penetrating your house, but really lousy at dealing with interference. Add to that the fact that the low bandwidth can't carry a lot of data. It takes an entire minute for the radio to receive just one complete sync signal. That means if you get any interference or loss of signal during that cycle, the watch will need to wait until the next cycle starts and try again. It will only try this 15 times before giving up. (Apparently to save battery power.)
Now that my stuff is working, I'm pretty happy. I think this product would have done better with some better documentation.
