Love this watch! Really came close to a smart watch but I love the weight and look of a masculine watch. The Bluetooth I was worried about, but after setup it’s awesome. Finds your phone and plays a tone within Bluetooth range…but it’s awesome and sturdy and solar powered!

Best watch ever although I am so scared to scratch it! Looks amazing, feels awesome to have on.It takes some getting used to from the rubber style watch bands that stay put though as this slides about. It is also very large and pokes out a bit so can take some getting used to when it rubs into your hand. Got mine adjusted by a jeweler and still not the perfect fit but getting used to it.Definitely a show stopped and has all of the executive functionality I want with an awesome look at a fair price. You seriously get so much watch for this price. Even looking at $7K watches their world clocks and complexities don't function or look as good as this and they also don't have the shock absorbing power, blue tooth, solar power and more.Hope GShock makes this for a long time and eventually goes down in price. I want to buy a second one that I put a more regular band on so it doesn't shift around as much on my wrist. That much weight shifting around can actually kind of hurt the hand, but hey sometimes you have to make sacrifices for beauty. This looks fantastic when I am on stage and on camera for my investor conferences.

I don’t think it’s all that big of a watch. I have 8” wrists and it looks fine on me.Overall the watch is very nice and definitely tough.I’m sick that I paid $400 and then when I come to write the review it’s $360 something but oh well that’s more of a reason you guys need to get on with it and buy this watch

This is a awesome watch, very well made in my opinion, The features using the smartphone App works great, I hope to get plenty of years use from this watch while traveling all over the world,This is the most I’ve ever spent on a Casio G Shock watch, but in the past they have served me well no matter how much ruff use they have received, hopefully the rechargeable battery will hang in there for a long time,Another thing I want to add is adjusting the stainless steel bracelet was so easy, the spring bars just push in with a paper clip to remove the links for sizing and go back together in reverse order, very simple to do, nice feature Casio!!!

The GST-B100D-1ACR is a good-looking, masculine watch that's a little more upscale than your average G-Shock.The Good:- solar power- easy to read analog hands and date window- LUMED HANDS (I don't know why Casio futzes around when describing this feature; YES there's a LED light and NO there isn't any lume on the dial's metallic pips but YES THE HANDS ARE LUMED, not a Superluminova level of lume but there's LUME)- famous G-Shock durability in steel -- not 100% steel but steely enough- buttons easy to press- awesome design with extra points going to the dial's rotorThe Bad:- The G-Shock Connected app (Android 13): Downloaded directly from the Google Play Store, Casio's bluetooth watch app might not work, giving you a confusing "This app cannot be launched because the animation is turned off" error on the Terms of Use screen, which you can't get past unless you fix the problem. Casio's solution is obscure and reddit's problem solving info is dated. -------- For Android 13, you need to go to Settings > System > Developer Options > get carpal tunnel scrolling for Window animation scale, Transition animation scale, and Animator duration scale, and change these settings from the default 1.0x to 0.5x. Stupid and frustrating.UPDATE APRIL 28, 2023:Casio has a new app called 'Casio Watches' and there was no problems syncing my watch to the app. Unfortunately, the 'manually adjust hands feature' does not work for the fraction-of-a-second alignment needed to get the second hand dead center of the 12 o'clock pip. So once again, good, but not great.The Ugly:- The second hand -- one of the big selling points and function-intensive parts of the watch -- does not completely line up with the 12:00 pip or the other pips. Not a deal breaker, but for a watch in this price range a quality glitch like this shouldn't occur. Note this specific G-Shock has a code ending in CR (made for the US and Americas, Japanese parts, assembled in China). If I knew this was a common problem in this watch, I would have purchased an all-Japanese model, hoping to get one with better quality.Still, despite the quirks, this watch is a looker and easy to use and maintain (after you get the app working :P ).

My G-Shock B-100D arrived in the mail today and first I got to say how eye catching this watch is in person. I was disappointed a little bit because Casio is going to be doing away with the G-Shock App after July 31, 2023 in favor of the new updated Casio Watch App. I like the G-Shock app better but oh well. So I downloaded the new app and it was still very easy to connect the watch and set my local time and my world time through the app. It is a little trick when it come to removing links to get the watch to fitch your fit your wrist but now still manageable enough to accomplish. Other than that, I got to say this is better than all my other G-Shock’s. Shoot it is even better than my Casio Pro-Trek series watch that I also own. This this far is the best timepiece Casio has come out with thus far. This watch is a must buy.

I have been waiting a very long time for g shock to come out with a steel bracelet and watch. This bad boy delivers! I feel like James Bond wearing this watch. it makes me feel way cooler than I probably am but my wife says I'm pretty cool so I'll go with what she says. This watch is just like icing on my coolness cake. Cool factor 10+. Functions are killer, Bluetooth connectivity keeps the watch as accurate as as the atomic clock, pretty darn accurate. Only had one alarm which is fine. The bracelet is easy to size, just use a paper clip to remove links. A tad loose is the best way to have it sized. Great watch, killer looks, adds plenty of cool to your average James Bond wannabe
