I purchased this watch for work and exercising and after using it for a day I'd say it performs admirably; one certainly cannot complain about the price. Shipping wasn't particularly cheap, but Fed Ex 2 day never is. Stopwatch and timer functions work perfectly, but appear limited to 23:59:59 at max. The daylight savings toggle is handy, and Casio allows a one or two button combination to rapidly set the analog dial in increments of about twenty seconds. The alarm is moderately loud, on par with every other Casio I've used. 30 cities to choose from for world time is a nice bonus if you care.

Some annoyances:

The 'illuminator' light ring is VERY poorly designed and appears to consist of two yellow LEDs embedded in a clear plastic ring under the outside edge of the 'crystal'. When in use, analog time is just visible but the recessed LCD screen is totally unusable. If low-light or nighttime use of the stopwatch or timer is important to you buy something with an electroluminescent face instead of this.

The 30 entry data bank function is probably very handy in a pinch, but entering letters and numbers by using the two watch buttons is incredibly slow. Use your cell phone or a little black book.

The numbers on the outside of the dial are redundant with the ticks on the inside of the dial. One or the other would be preferable for aesthetic reasons.

The battery will probably not last nearly ten years if the analog time is adjusted often or the 'illuminator' is used too often.

I prefer leather bands over resin, but that can always be swapped out at a drug store or mega mart. 4 stars

The 'crystal' of this watch is in fact made out of plastic, which causes it to become marred and scratched nearly as soon as it's removed from the containing box. The backlight is almost totally worthless and the databank function is unusable with a total of four buttons. The analog dial does not even feature a second hand.
Avoid. 1 star

I also bought this watch & spent extra money because it is advertized as "Thermometer". There is no thermometer on it. Very cheaply made. 1 star

Watch I got was not equiped with thermometer although the picture matched the product. Mine was some memo/phone number featured watch.

It's a good product at a good price, but I don't know why it was billed as a thermometer watch when it has no thermometer. A Casio watch I ealier owned actually had a thermometer. Also the count-down timer has no alarm, which seems unusual. But these problems are not so substantial that I want to return the watch. 3 stars
