I am G-Shocked! (GW7900B-1 review w/pix!)

Introduction. For a year I had considered obtaining a Casio G-Shock watch. I had looked at the Men In Orange and Mudmen models. I liked the features, especially the atomic clock time setting function, but not enough to pull the trigger. Then I received my weekly copy of Time Magazine.

The December 28, 2009 issue rated the Casio GW7900B-1 as a Top Ten Gadget of 2009. Having researched other Casio G-Shock models, this model piqued my interest.

I ran a search and found the GW7900B-1 featured a bevy of functions. It had the atomic clock time setting function, and solar power, moon phase, chronograph and alarms. What floored me was the reasonable price! $150 retail seemed extremely reasonable, so I pulled the trigger - but not before I found a better price on the 'bay.

Packaging. The packaging and presentation surprised me. Considering the price point, I figured the GW7900B-1 would arrive in a plain-Jane box. It did arrive in a box, all right - but within a very nice G-Shock tin enclosure that I did not expect. A comprehensive manual (that I am still studying) accompanied the watch.

Operation. I haven't mastered all of the GW7900B-1's functions yet, but, so far, its operation seems entirely straightforward. Of course, reading the manual facilitates operation. Manual atomic clock time synchronization, if needed, is easy and prompt - though it helps that I am located less than a hundred miles from the WWV atomic clock transmitter. Time zone changing is very easy. The dial illuminates easily with a tip of the wrist and there is a manual dial illumination function.

Comfort. I own and wear several large watches, including UTS, Ball, Vostok-Europe Ekranoplan and others. The GW7900B-1's 52.4 x 50.0 x 17.7 mm dimensions made me expect a behemoth. Not at all - the watch seems smaller than it measures and suits my 6½-inch wrist nicely.

Comfort is wonderful, I think because of the watch's light weight and curved extensions protruding from the caseback. The extensions curve nicely to the wrist and really help the watch fit well.

Conclusion. The GW7900B-1 packs a lot of punch for a reasonable price that is likely to become more reasonable as more production ships. The watch is very functional. Quality is excellent.

I'm glad I finally got a Casio G-Shock. If you have never owned a Casio watch before, try a GW7900B-1. You'll like it.

I have two on order from the USA at the moment, can't wait!
I haven't owned a G since a weird ana-digi model with a grid pattern on the analouge dial that I had when I was in school....I still own it, somewhere....but this black rescue caught my eye while browsing this forum, had to get one.

I'm already liking the look of a green mudman in my local ADs too...arghh!

A question to all owners of the GW-7900. Does not matter if its positive or negative display (7900B).

Question: How do you know by looking at the tide display what the status is? WAS it low tide moving into high tide, or, IS it high tide moving out of high tide into low tide?

If my attachment loads correctly, it will show the Casio G9100's Tide graph and how it shows the status of the tide. I scuba dive all around the world and want to know that this $220 watch shows me wich way the tide is going. ($220 in China / $150 in USA)

In my pic, you can see that it WAS high tide and now it moving INTO low tide. COOL! When you look at the tide graph on the GW7900, it shows you how big the 'tide difference' is (Spring, Intermediate, Neap Tide) and *maybe* shows that you are at high or low tide by a small flashing LED light, but does not seem to be able to tell you what 'direction' the tide is going into.

Please just compare my pic to the Tide Graph on the GW-7900 and you can see what I mean. I look at my G9100 and know that the tide IS at high, and is now moving out, into LOW tide. I know which direction its going.

I appreciate it, my fellow G-Shock collectors!

Aqualung...takes me back. :-d
I even listened to some Jethro Tull the other day.

Re the tide Q: it effectively works the same as the Gulfman's graph but with a bit more detail re how large or small the tide is. It's a basic left to right cycle which I believe changes every 2 hours. That is not very accurate because massive tidal shifts can occur within 2 hours as I used to work a lot in mangroves.

The Silencer (GW-400) has easily the most accurate tide graph of any G with resolution of one hour if you need that.

Another, even more accurate digital watch for tides is this Rip Curl model but it doesn't have atomic/solar.

I used to listen to Jethro, but Aqualung is a scuba gear manufacter. It's more of a scuba nick name, not based on good ol Jethro... I'm a deep sea diver/Trimix diver, for sport.
As for the GW7900, do the columns flash, from left to right, as the tide range changes? I read some internet articles and they seem to show a flashing column in the graph, on the pictures i've seen..

In dim light I find it readable but in what I define as low light I use the light. The light lights up the time and all other info. It does not light up what I guess is the background area. It does present very well to me and I like that has the option of staying on 1.5 seconds or 3. It also has the auto light where it will come on when you turn your wrist as if to tell the time.
