I own four different Casio watches. I needed one to wear when shooting sports photography, where a heavier watch, with protruding buttons and dials and metal straps or clasps would be a problem since they tend to get caught on the various straps and other bits on the camera system I use. Since I work with international photo agencies, on very strict deadlines, it also had to have a world-time function. I also prefer an analog face. This watch fit every need perfectly.  It's feather-light, with a fabric and Velcro strap, and no protruding buttons or dials. It's got a complete and simple world-time function. And I have to repeat; it is both comfortable and LIGHTWEIGHT!  I often forget I have it on. It looks good, too. And all this for about $20!  Amazing. I'd buy one again in a second.
