Like others, have had my eye on this for a while then finally decided it had to be purchased. You won't be disappointed. Pretty much the most complete world-time watch on the market. It has 40+ cities in it, not just one for each time zone. Plus it looks and feels awesome. The alarm functions work fine, but volume is semi-low, especially if you have hearing loss in high frequencies.  UTC time is always displayed along with your home area time on the left digital display, and the city of your choice on the right side. Remember to set alarms in the time zone you are in. Switches time zones easily, leaving one on display in addition to local and UTC time. Hands glow brightly all night, not tritium but a very lively form  of phosphorescence.

Drawbacks?  Digital displays are hard to read at twilight or low light.
