Citizen's featured mainstream new watch collection for 2010 is this Eco-Drive World Time Perpetual AT line of timepieces. This watch is model number CB0020-50E and features a black face with a stainless steel strap.

The watch has a perpetual calendar. When you set the time, you also set the month and the leap year. Given continuous operation of the watch, the calendar doesn't need to be set again until the year 2100.
In addition to the light power generation in the Eco-Drive movement, the watch receives signals from various atomic clock radio signals around the world. It syncs with these regularly to keep the time accurate. It even does this when you are traveling.

In addition to the auto syncing you can manually sync the watch time. This is another great feature to have and gives you assurance that the time is most always correct. Even if the watch isn't able to sync with an available signal, the quartz movement is still accurate.

And then there is the world time function. The list of reference cities around the dial are used when selecting different timezones. You can easily switch to any of the major timezones without losing accuracy on the watch. Citizen makes it pretty simple to adjust, thus allowing for a great traveler's companion, or timepiece for people who like to easily know the time in lots of other timezones.

The little "SMT" indicator on the dial is for turning on and off day light saving. The other area is part of the manual sync functions for the atomic clock synchronization. Otherwise the dials are clean, and with the large hand and applied hour numerals (both coated with luminant) this is a very legible, sensible looking high-function timepiece!
