Today let's look at the G-Rescue G7900A-7, introduced in May of 2009

Might be useful in noisy, dark settings to get your attention.World time is present as expected, and since the watch uses UTC offset and lunitidal interval to calculate tides, you can enter a fractional offset -- perfect for places like Delhi and Australia.Today let's look at the G-Rescue G7900A-7, introduced in May of 2009:Inspired by search and rescue teams (thus the name).Bigger buttons for gloved use -- largest ever on a g-shock.Back case shock absorbers (pictured below).Low temperature rated display (-4°F/-20°C).And of course the long list of normal g-shock features:Water resistant to 200m (660ft).Auto and manual electroluminescent backlight.Flash alert (backlight flashes with the alarm).World time.Five alarms.Two stopwatches.Moon and tide graph.Please read on for the full review. The G-Rescue line is in an enlarged case which is shaped slightly differently than its predecessors with new bezel screws.The newly enlarged buttons are easier to use and a nice improvement overall. Easy to press, but still reasonably shielded from bumps. I wore it for a week of assembling furniture and unpacking boxes, and was very happy with it. It seems like a good choice for anyone working on the ocean, with its *** displays of tide and moonphase.The G-shock line has been around since 1983, so it's quite impressive to see how they're still innovating and improving, yet still keeping prices down. This is a great watch -- inexpensive and tough as nails. Our thanks to Casio PR for the review watch; much appreciated once again.
