Bad things/ Weakness for this CITIZEN SKYHAWK-A-T Models:
(1). Snap-On back cover (Not a screw down back cover)
(2). Crystal is made of mineral glass (Not Sapphire Crystal) and slightly domed.
(3). One other annoying thing is that to access the various functions of the watch (calendar, countdown, chronograph etc), you have to pull out the crown and rotate it. A bit annoying if you use the functions a lot.
(4). There is no hourly beeper/ chime feature.
(5). It's really is annoying not being able to display the date in your current time zone.
(6). Stainless steel band quality is cheap because of it was made in China.
(7). This is not a Japanese Domestic Model like U680. It's meant the watch overall quality is little bit lower than domestic models. Available in Europe, United States and Asia.

Questions & Answers:
Q: Will the Skyhawk A – T automatically change time zones and adjust time accordingly?
A:
As the Skyhawk A – T does not know where you are located (no GPS system), you must manually adjust the radio control time zone shown on the left digital display (digital display 2). As the analog time is run from the radio control time, this will update as well.
Q: How do I know if my Skyhawk AT updated via radio signal?
A:
Normal radio updating on the Skyhawk A – T will adjust the time by a second or fraction thereof. As such, there is no visible cue to see the hands change.
You may however check to see results of the last update attempt. While in the time, calendar or reception set modes, press and release the lower right button. The second/signal strength hand will move to indicate either a high, medium or low signal. It may indicate that no signal was received.
If no signal was received, rest assured your watch is keeping accurate time to specification of 15-20 seconds per month (note: many users find the Skyhawk A – T keeps time to 1 to 5 seconds per month, even without radio signal updating)
