    Debating between a Gulfman or G7900 or looking for a red G-Shock? The G7900A-4 is awesome!, February 10, 2011

    I have been eye-ing the Casio G-Shocking Rescue Red G7900 for some quite time. Casio has released several colors of this G-Shock, one being a limited edition negative display of the red version, but other colors such as white, olive green, black, and another black but with yellow display.

    But what caught my attention is the moon and tide graph. I have a Gulfman and G-Lide and the tide and moon display for the G7900 was one of the best I have seen out from Casio thus far. The display is nice and clear, not many obstructions as you get a circular moon tide graph on the upper left, tide graph on top and on the right, you get stop watch modes (for stopwatch 1 & 2). The larger display is the time and date.

    Of course, aside from the cool display and what really pulled me in was its red color. The red bezel and band really pops and love the black highlights throughout the watch. Unlike other G-Shock red watches that have orange, this one is red and black and really enhances an outfit (especially if you were a lot of dark colors, especially black and blue). This watch definitely compliments an outfit.

    As for the back case, it is stainless steel and you get the usual G-Shock Resist on the back.

    The battery used for the G7900A-4 is one lithium battery (CR2025) which lasts approximately 2 years (normal usage). Accuracy at normal temperature is +/- 15 seconds a month.

    Now, the band for the Rescue Red is also awesome looking! It doesn’t have a shiny look but more of a matted resin look, which I like. The band is quite comfortable, but while not as perfect like the Mudman strap, it still fits comfortably on your wrist and at the base of the strap which connects to the case, there is a black guard that goes over the bumps of the band. Some people complained that watches with those ridges near the base hurt their wrist, so I felt that it was smart for Casio to include those black plastic guards on the back.

    I. THE FUNCTIONS

    The G-7900A-4 features the moon and tide display on top. Day indicator on top and at the bottom is the time, seconds and date.

    Pressing the illumination button on the front gives you an aqua light which is the blue and blue/green illumination that many G-Shocks do come with. This G7900A-4 has two EL (electro-luminescent) panels that cause the entire display to glow for easy reading in the dark and also comes with an auto-light switch, if set, by a slight angle movement will make the light turn on. I have this turned off because I want my batteries to last long! You can set illumination from 3 to 5 seconds.

    The modes that come with the Casio G-Shock Rescue Red G7900A-4 is:

    * Timekeeping Mode
    * Tide/Moon Data Mode
    * Stopwatch Mode (ST1)
    * Stopwatch Mode (ST2)
    * Countdown Timer Mode
    * Alarm Mode
    * World Time Mode (48 Cities/29 Time Zones)

    The stopwatch modes have a display range of 999 hours, 59 minutes, 59.99 seconds and there is auto-start. As for alarm mode, is good and audible. You can also mute the tones as well.

    II. THE BUTTONS

    The buttons are black and flat and not steel and have a feel similar to the Mudman’s but of course, where the Mudman’s are designed to keep mud out and takes much more pressure (and for some people, much harder to press), the buttons are easy to press on the G7900. There are four buttons and for the most part, one should not have problems with selections.

    III. WATER RESISTANCE

    The Casio G-Shock Rescue Red G7900A-4 is marked at 20 Bar which means and this means you can go scuba diving and snorkeling with it.

    IV. TIME & MOON GRAPH DISPLAY

    The Casio G-Shock Rescue Red G7900A-4 features a circular moon graph on the top left of the display. The moon phase indicator indicates the current phases of the moon as viewed at noon from a position in the Northern Hemisphere looking south. The watch performs a rough calculation of the current moon age from day 0 of the moon age cycle and the margin of error of the displayed moon age is +/- 1 day.

    The tide graph has six graphic segments, each of which indicates tide level. The tide graph displayed on the watch is based on the current moon age. The greater the error in a particular moon age, the greater the error in the resulting tide graph.

    IV. OVERALL

    I absolutely love this watch! It scores high on style (looks great if you wear a lot of black or darker clothing), high on comfort and the display, is stylishly cool, especially if you are looking for a larger tide display on a chunkier watch. The functions are awesome and you really get a lot for your money for the 7900 (I paid $64.99 during the holidaysfor the Rescue Red but they typically sell for under $90) and you can often find various versions on sale on Amazon by Amazon or third party fulfilled by Amazon as…

    When I saw the cool red color of this watch i had to buy it…everyone should have at least one watch that is unique and stands out from the dreary black/white world of normal everyday watches…these G-Shock Casios (I have a few) are so rugged, extremely well built and reliable they will probably outlive us all. The only reason this gets 4 stars from me instead of 5 is that the initial set up is somewhat complicated and time consuming…whatever you do, DO NOT LOSE THE OWNER’S MANUAL!…you will need it!

    I have been collecting G-Shocks for the past year now and i have eight. this is my sixth watch and i have 3 reasons why this watch rules.

    1. It is one of the most stand-out watches ever. It is the scarlet red and the broad feauture that makes this watch an eye popper.

    2. It is one of the only red watches that looks AWSOME! this watch is legen- wait for it-

    3.It has so many amazing features and has tidal features ans also wave calulations such as low and high tide. This watch is a MUST BUY for someone who likes and buys many shocks.

    It is still in geart condition. No scuff marks have been found on this watch yet and it is water proof up to 200 meters. MUST BUY! the shipment from this buyer was amazing and quick. Even the free super saver shipment was quick. EXCELLENT EXCELLENT

    - dary…LEGENDARY!
