Great Aviation Watch,
This review is from: Citizen Men's JY0000-53E "Skyhawk A-T" Eco-Drive Watch (Watch)
Just bought this watch and it is much better than I thought. It is larger than average (I have been a Casio G-Shock man most of my life), very solid, easy to read dial, although some of the lettering is smaller than I would like. The digital readout I like so much for UTC is somewhat smaller than I would like, but no strain is needed to read it. It also has a backlight, which is nice.
The atomic feature is also very nice for those who like absolute precision. It basically works this way:
The watch has a receiver in it that receives a signal from the NIST (National Institute of Standards and Technology) transmitter in Ft. Collins, Colorado once a day, usually at night. It then synchs the watch with that time, which is the official U.S. time. It does this every day at the same time, or you can manually synch it yourself. Or you can set the time manually.
One note on synchronizing the time. The radio signal you receive is very low (60 hz), so it is very difficult to receive during the day. Sometimes during the day it will not even receive the signal, but in the middle of the night it will get the signal at maximum strength, even inside the house, and I live in Florida.
Citizen makes probably the highest quality watches for the money, and are always a leader in technology.

The radio signal is actually 60kHz not 60Hz which is the AC current frequency.
