 Two Thumbs Up for G7900-1!Oct 14, 2009
By Steven Maes
"Schenker Fan"
This just arrived in the mail today and here are my observations:
It's a big watch but it doesn't feel like one. The cuffs on the inside of the band make this the most comfortable G-Shock I've ever owned - especially since I have a fairly small wrist. I had previously ordered the Gulfman because I wanted the Tide Graph but it just didn't fit right and it wasn't comfortable. After searching for another G-Shock with the Tide Graph I found this one (the G7900-1) and it's great. I like the fact that it has 5 alarms and a countdown timer in addition to all of the other features. The styling is nice and modern, it's easy to read, and the red button in the lower right side gives it a nice touch. The moon phase indicator is nice and large too.

Awesome WatchDec 20, 2010
By TamandAl
Love this watch.....Setup was a little difficult, but once I figured out the tide/moon settings I was off and running. Well made, beautiful, and very functional.
Don't over-complicate the tide/moon settings. Here's the easy way: Go to one of many graphs on the internet and figure out the moon rising and moon setting times for the next full night. Next, calculate the time exactly half way between the two. That gives you the High Moon time, that is, when the moon is highest above your house. Now get a tidal chart for your area and write down the time of the NEXT high tide after the High Moon time you wrote down. The tidal charts are all over the internet. The amount of time from your High Moon time to your next High Tide is the Lunitidal Interval that needs to be set on your watch. It's NOT complicated and is easy to set when you figure it out. The instruction booklet makes it sound way too difficult. Good luck....Hope you like the G-7900 as much as I do.

Rugged and an a useful training toolDec 01, 2010

Strong looking and solid to wear. Everything you need to train with. 5 Alarms, 2 timers, 1 countdown timer that can be set to auto repeat. A must have that seems to be lacking on some of Casio's better models. Casio better wake up and realize that the auto repeat timer is a valuable asset to people who stay fit. Use this watch with confidence and know that it is a Casio G Shock. Maybe a slightly slimmer package on the next model. Other than that thought, great piece.

 Good watch, big, easy to useNov 30, 2009
By Miguel
I purchased this watch but ultimately returned it to seller.
Pro's: easy to read, nice alarm feature, easy to make adjustments, was exactly as it appears on the site.
Con's: for me personally I wish the watch was all black - I didn't really like the Red on the face, or the red button on the side. It would be cool is Casio made one of these that was all black but wasn't millitary/super dark.
If you are looking for a quality digital watch I think this would be good for you.

Another great G-Shock!Oct 02, 2009
By DMA

This is my third G-Shock watch in the last 25 years. My first lasted over 15 years; my second (DW-6900), sadly, was lost on a recent trip to Canada. I almost got an exact replacement, but it occurred to me that this was an opportunity to upgrade to a G-Shock with more features, so I started looking at the new line. I considered the upgraded version of my old watch, dubbed the GW-6900, but it was a 4-6 week wait time thru Amazon, and I didn't want to be without a G-Shock on my wrist for that long :)
I settled on the G-7900 as it had an interesting display layout -- not quite as symmetrical as the DW/GW-6900, but very readable -- important since I am now in my mid-40's, and I can't always locate my reading glasses! No atomic timekeeping or solar recharging, as on the GW-6900, but I realized that at this point, I don't really need those features.
The G-7900 has a nice, beefy feel to it, and though I was a little dubious about the rubber "wings" attached to the strap, they actually make the watch more comfortable to wear by keeping it from moving around on my wrist. I also much prefer the G-7900's chunky rubberized buttons over the smaller round metallic buttons on my old watch. Another great feature of this watch is the ability to move forward and backward while setting time, alarms, etc. - my old watch would only allow forward movement through the settings, so if you missed the mark, you'd have to go all the way around to it again - seemingly a minor thing, but I did find it rather aggravating. The G-7900's moon phase feature is cool, but since I live in northern Texas, I doubt the tide feature will get used much :)
About the only thing I can think of that could be considered a minus would be the backlighting; it's not as bright as the backlighting on my old watch. I will say, though, that the watch is readable in all but the lowest light, and in very dim settings, the backlight is quite adequate to illuminate the display. Maybe Casio implemented this dimmer lighting to save battery life?
Overall, I have to say that I LOVE my new watch. If you're a G-Shock fan, I would suggest that you take a look at the G-7900; if you're not currently a G-Shock fan, check one out -- you, too, might find something new to love.
