Casio G-Shock Go Green GR7900EW-7 Japanese watches

With its recycled paper packaging and Tough Solar power technology that allows the new Casio G-Shock Go Green GR7900EW-7 to work literally for years without the need to change its onboard battery, the digital electronic watch looks like a nice choice for environmentally-conscious customers with a taste for active life style. Perhaps, the only thing that could probably scare them away is white rubberized plastic used for its outer case: it will get dirty in no time and will get only dirtier as the years are passing by.




Traditionally for the series, the new Casio G-Shock Go Green GR7900EW-7 is by no means small seriously limiting the choice of outfit you could possibly wear with this timekeeper. Well, if you only plan to wear one in a gym or use it with other types of sports activities, this shouldn’t be a problem.

According to the Japanese company’s press release, the watch will be delivered in a massive 52.4 mm x 50.0 mm case. Made of white resin with an extra steel “cage” holding the electronic module, it is whole 17.7 mm in height, which may make it a bit too bulky for some potential owners. On the other hand, the extra millimeters are here not just for your visual pleasure: all this rubber is supposed to dissipate shocks that would otherwise be able to ruin either the fragile mechanism or the monochrome LCD screen. After all, the watch is primarily designed for adrenaline junkies leading an especially active lifestyle.

However, despite being relatively big, the watch -just like most other members of G-Shock family- is not especially heavy tipping the scales at around 71 grams or slightly less than 2.5 ounces.

The GR7900EW-7 is powered by the well-known Module 3270 “movement” and therefore sports such useful features as full auto EL backlighting with afterglow, battery power indicator, full auto calendar good till year 2099 and world timer for 31 time-zones and 48 cities.

Although I have an impression that such functions as tide graph calculator is a bit superfluous for most potential owners, the stopwatch and countdown timer may be quite useful for those who doesn’t dare to bring his or her expensive smartphone anywhere near lifted, pulled and abused in any other way heavy hardware, but still doesn’t want to spend money on a specialized device.

Another nice thing about this watch is a “green” power saving mode that increases the timekeeper’s time of operation more than 2.5 times as opposed to normal mode: really useful if you don’t plan to wear this little green monster on a daily basis.

Consider this, when the battery is fully charged and the gadget is left in total darkness, it continues to operate for as long as 10 months. However, if you activate the power saving mode, the watch will work for as many as 27 months!

Capable of serving as a replacement for a diving watch, the GR7900EW-7 sports water resistance rating of 200 meters. It also displays a “tide graph” on its monochromatic LCD display.

The watch will go on sale next month at a more than affordable price of $130.
