I have had the GW7900B for a year and a few months now, and I am very happy with it. The watch is all black, and the digital face is inverted so that it is black with light gray for the numbers. That means the watch is pretty much all black, which is a very nice look. The inverted digital face does make it a little tough to read in low light situations, but the G button just below the watch face lights up the time, date and other information with the same kind of indiglo effect that I have had for years with Timex Ironman watches. The lighting effect makes this watch easy to read at any time. You also have the option to have the lighting effect happen with the turn of you wrist so you can see the watch information without having to push a button. This is a large watch. The body of the watch is almost 3/4 of an inch thick, which is the thickest watch I have come across. While it is a large watch, it is very light, because most of the body is plastic. The face of the watch is scratch resistant, and it is recessed into the watch about a quarter of an inch, so it is well protected.

The watch is loaded with features. 1) The time is set every night through radio signals from an atomic clock. Every night at a few minutes after midnight the watch will try to update the time from the atomic clock. If it is unable to update the time, then it will try again every hour through the night until it gets an update. This makes the watch very accurate. It has been off by less than half a second from any of my other atomic clocks or the atomic time that you can get over the internet. This will be the most precise watch you will probably ever own. 2) The battery on the watch is recharged by solar panels in the watch face. The fully charged battery is supposed to be able to last about nine months without a recharge, but the solar panel in the watch face picks up a charge in direct or indirect sunlight keeping the watch battery topped of unless you hide in a dark room all day. When I first received the watch the battery indicator showed the battery was a little low. I put the watch in indirect sunlight by setting it on a table by a window that the sun does not shine through. About 3 hours later I checked on the watch, and the battery was fully charged. Since then the battery has remained fully charged with just the partial sunlight the watch gets from me commuting to work. So I don't expect any battery problems. A cool feature for those of you who may not use the watch for a while, it turns off late at night and will not turn back on until you pick it up. So the battery does not drain much if you do not use the watch. 3) I travel across the country for work, and the watch is very easy to reset to other time zones. It also has a world time feature that lets you check the time in every time zone around the world just by clicking through the different zones. 4) Like just about every digital watch this one also has a stop watch. The stop watch capabilities are not as thorough as sports watches. For example, you can get a split time, but you wouldn't be able to take several split times like you could with a Timex Ironman watch. 5) The watch has a countdown timer so you can let yourself know when you need to stop what you are doing and move on to the next thing. 6) There is an alarm function that allows you to set four alarms and one alarm with a snooze feature. 7) The watch shows the phase of the moon and where tide is. 8) The watch is water resistant to 20 bar, which converts to something like 170 meters. So you can pretty much wear the watch in most underwater conditions you will find yourself.

So to wrap things up, this is turning out to be a great watch for me. It is super accurate, does not look like it will ever need a battery change, and looks really nice. I recommend it, and I would buy it again.
