Not sure what the city selection thing does, but I really like the watch, it works in the pool, and looks nice. The size is fine as well. I wanted analogue to look good, digital functions for time studies, etc.

Edit: It was good to start with and it grows on me. Lightweight, easy to read at night, the analog function shows during hand-reset, so when I went to another time zone I didn't have to remember the minutes to set the hand. I probably ought to dig into the instructions so I understand the features, but the fact is it does the trick and is brain-dead easy to do usual things to it, unlike some more complex Casio analogs.
