I bought this watch in the fall of 2003. Unlike others, I have had no major problems with it until about a month ago, when the battery lost its ability to take any kind of charge. Up until that time, the only things that went wrong with the watch were due to its daily use. I had to replace the watch band a couple of years ago, and the blue backlighting went out about a year ago, but I consider both those to be expected, especially considering I used it daily for 6 years. The small things on watches just wear out with heavy use; I accept that.
These issues aside, I was very happy with my watch purchase. I learned how to use the watch and appreciated the fact that it was ALWAYS on time. Since I work a lot with satellite timing in my job, that was a very welcome feature. I also liked the multiple time zone settings and automatic Daylight Savings Time adjustment, (that is, until the stupid Government changed the DST rules for no reason a few years back). Like most people here, I had absolutely no use for the time record feature. I would MUCH rather have had a countdown timer instead.
The one thing that always bugged me when reading the (huge) owners manual for this watch was Casio's claim to unlimited battery life due to the solar feature. This is simply not realistic. Current battery technology produces a battery that will last up to 5-6 years before the chemicals inside start to oxidize and lose their effectiveness. Even if the battery lasts much longer than that, many other electronic components inside the watch only have an expected lifespan of 10 years or so. Either way, you will be buying a new watch within a decade or so-much sooner than the manual leads you to believe.
All told, I am still glad I bought this watch, and I am not disappointed at the battery life, as it worked as long as I realistically supposed it would. However, now that I'm in the market for a new watch, I will hold out for an atomic solar watch with a countdown timer feature.

I purchased this watch about 5 years ago and am finally getting around to reviewing it.
This is the quintessential bus driver's watch. That's what I did for a living at the time. In an agency of 2600 drivers, this is by far the most popular watch that doesn't have the company logo on it, I will go into the reasons for that later.
I actually purchased the watch for use with a sextant (!) I wanted the time-stamp function on top of the atomic set time. The solar was a plus but did not finalize the choice.
I have only had the battery level go below "High" once, due to riding my motorcycle for a month straight in the winter.
Key features that influenced my purchase:
- Atomic clock set (from Colorado)
- One touch time-stamp function
- Solar powered
- 5 alarms (1 "Snooze", 4 Reminders) (Loud enough to wake me)
Bonus features I discovered or started using later.
- Optional auto light
- Multiple timezones
- Stopwatch
- Rugged
Now, for a bus driver the functions that are truly important are:
- Atomic set - Always being set properly
- Auto light - You can check the time in the dark one handed
- Time Stamp - record the time of an event for a later report
I ran the battery down the one time because I had auto-light turned on and was wearing gauntlets when outside. the light kept coming on and it rarely saw the sun. I learned that trick and got the battery re-charged over a couple of days.
I love this watch, it has lasted longer than any other watch I have owned. The face is un-scratched and the band is nearly original condition, but the housing shows real world experience; the chrome parts have worn down to the plastic in spots, there are gouges in the rubber housing parts, the buttons have worn in ways that indicate where my nails have pushed on them, the lettering on the outside of the case is no longer filled with pigment. It has character.
I now work in more of a technical field, and am considering getting a more formal watch but am unable to give this one up.
If you can find one, this is a wonderful work watch especially if you work nights.
One disclaimer, a co-worker has one about the same age and it won't take a charge anymore. After all, they are based on a chemical battery, so will likely die after a while.

I give this item two stars based on the battery performance. Recharging the solar battery only works less than a month after two years of use. That said, I'm giving solar one more shot with a new AWG101-1A. If I get the same results I'll quit buying Casios.

I've now had my GW 300 for about a year. It's one great watch. I'm a paramedic and work on an ambulance so it gets some rough treatment from time to time, but it's never let me down. As others have noted, it's a rather large watch and sticks up up off my wrist about 1.5 cm's. And it's not particularly flashy or sexy. But it does keep very accurate time, and that, to me, is the primary function of a watch.
The only problem I've ever had with it is the feature that activates the backlight with wrist movement. It doesn't always work when I would like for it to, but on those occassions I can push the button to activate the backlight.
I too have a wall mounted atomic clock in my home. It is amazing to watch the two change time together, down to the second.
There is just nothing quite as neat as knowing that the time on your wrist watch is totally accurate. I like it.

I have had this watch for a couple of years and just now it is becoming unreliable. The battery is down to low and the watch will not function even though I have tried charging this solar watch. I have contacted Casio about the problem and am waiting. Before you buy this watch do a seach on Google and and type in GW300 problems and you will see hundreds of people who have had battery problems. Otherwise this has always been
MY FAVORITE WATCH !!! I never took it off til just recently. Thankfully I have many other Casio and other watches as back up !!!
