    Built to last. Perfect for active people!

    This G shock most definitely lives up to it's heritage! I looked at many so called tough watches before this one. For the price it can't be beat some that where a lot more expensive but none any tougher. My biggest problem is the back light not all that useful in the dark. It works but hard to see at just a glance. This was my first G shock and have been very pleased with it I've put it through some punishment given my profession. I'm a tradesman I've knocked banged and pulled it every way but loose! That band held together just fine like the 2 prong on the band gives it extra stability. Also

    Center of Attention, great watch!

    To start off, I ordered this on a saturday evening, and received it via UPS on Tuesday around 7:00PM, and that was one-day shipping.Anyways, the watch has some really cool functions, and looks amazing. I've owned $20 watches at Walmart/Meijer stores, Rolex, Omega, and I've recently been using an iPod Nano 6 with a white Nanotch(tm) watchband. The G-Shock has a white matte finish, and if you're a student, or someone working at a cubicle and writes a lot, then it is a possibility that you could smear graphite (from the pencil or ink from pen) onto the watch, but you could wash it off with soap a

    Best watch for ourltdoor

    Best watch ever wouldn't dare buy any other watch. I work in fiber optic construction and trust me the watch takes a beating and it does take it and still performs.

    Not perfect, but very good.

    I got the white version of the GA-100 series (it's kind of gray to be honest, not bright white, but it's a good color). This is a large, reliable, dual analog/digital watch with a lot of features, including the unique ability to set a secondary time zone that you can switch to quickly if you travel across state lines a lot, or to a different country once a month, or something of that nature. For the past four and a half months I've worn this watch constantly - washing my hands, in the shower, going to sleep, working out, and it's lasted through all of that flawlessly without issue. I only took

    The, “Type O Negative,” G-Shock

    I love G-Shocks! They’re accurate and dependable. Rugged and look good. And they don’t cost a fortune. Fairly easy to set with a bit of help from YouTube and the owner’s manual. Had to figure out how to set the DST (daylight savings time) feature to, “auto,” as it was initially an hour behind after I set it up, but only took a couple of minutes of tinkering. As a career railroader, who dislikes constantly synchronizing watches, these watches keep excellent time. While this G-Shock is not one of their atomic watches, like others I own, it still keeps good time and I like its rugged looks and du
