One of the many things I love about this watch is it's ability to display the temperature very accurate. I've checked it many times with my phone's weather app and it has been consistently on track. Last summer I got a little too hot while mowing ( I own a landscaping company) and had to recuperate for a couple days before getting back to work. With this watch, I can set it to the "Temp" position and keep a close eye on it during the hottest time of the day. It helps me to remember to take breaks often and rehydrate. It's also tough. The carbon fiber bezel takes a beating and keeps on ticking (sorry Timex).Also, with Dillard's being an authorized dealer, I didn't have to worry about a fake or gray market item. All the paperwork, warranty information is in the box. ... MoreOne of the many things I love about this watch is it's ability to display the temperature very accurate.

I work in harsh kitchen environment as a professional chef. Everywhere full of water, oil and heat. I used to use a watch average of 3-4 months. Especially because of heat, they literally melted or suddenly stopped working. Keeping time is crucial when you cook and wrist watch makes my life much easier. Long story short, I bought this watch nearly two years ago and never looked back.After all that kitchen abuse, it still is going strong. Possibly last watch you ll ever need…

Purchased this watch for the look. Looks great with great features. I was like a kid at Christmas waiting for it to arrive. The watch after setting up would only stay connected to Bluetooth for three minutes then disconnect . The only way to get it to reconnect was to unpair it, delete the app, download the app again, re- pair the watch and completely set the settings up all over again. Did this seven times. Even tried it on my wifes iPhone 12 same issue. Spoke with Casio customer service tried a full reset to no avail. Determined defective. For $380 you would think you could get a watch that works, very frustrating. REI was great and took the return to be returned to Casio. Love REI !!! I’ve read a similar review on another model which adds the heart rate monitor ... MorePurchased this watch for the look. Looks great with great features.

Well made, robust watch. Well packaged and next day delivery. The watch face is easy to read under all conditions and it is comfortable to wear. A good size and sits comfortably on the wrist. The features are probably more than I need on most days but they are controllable and if you don't want them all you can switch them off individually, so a perfectly customisable watch. I haven't used it under water yet but I am confident it will perform as described. A good watch at a fair price and it does what it says on the tin so what is there not to like?
I bought this product so I had a watch for everyday use, had the watch a week and it self adjusted the time to an incorrect time zone and wouldn't allow me to adjust it back to my current time zone. So I disconnected the watch from my phone, then reconnected it. It still never adjusted the watch to the correct time zone. So I deleted the watch completely deleted the watch from the app. Then I went through the setup for the watch again and still no changes to the time issue. So I bought a different watch to replace the now $400 paper weight I have. I would NOT buy this watch again.
What a brilliant watch, functions are brilliant, the watch looks great, definitely a great comfortable watch to wear. Why only 3 stars, the strap. I decided to buy the orange strap watch as it stood out but unfortunately this is the issue. In a short space of time the strap has become discoloured, dull and looks dirty. I cleaned the strap after wearing the watch every time but no joy. I contacted Casio who told me this is what happens. So overall an outstanding watch but just dont buy the orange strap version.
A very lightweight and wearable G-Shock. The usual host of functions for the brand, plus Altimeter, Barometer, Compass and step counter. The watch is navigation focused with location indicator enabling easy pinpointing to your campsite, car park etc. The accuracy of this function is very impressive using Bluetooth link to your smartphone to log the location point. The watch can also be set up using the G-Shock app and the modes can be customised. Build quality is very good, carbon fibre bezel looks attractive too. To sum up, a wearable daily beater with a host of functions that looks at home in the office as does in the great outdoors.
Comfortable on the wrist despite being larger than average size mens watches and not too heavy. Very easy to read the time at a glance, excellent build quality with some useful features. Bought it at a really good price through H Samuel happily honouring their price match promise in store. Third watch bought from this retailer. The staff in the Gateshead Metro Centre branch are always very pleasant and helpful. A good place to get a nice quality japanese watch. Previously bought a GMW-B5000GD-9ER g shock online from this retailer, during an earlier sale, at a fantastic sale price with quick delivery. Highly recommended retailer
Well, what to say about this watch... other than it is pretty awesome!I have a few G-Shock watches now, ranging from the tiny Pikachu Baby-G to the beast that is the GWG-1000 MudMaster, the GG-B100 sits on my wrist more than the others now and is very worthy of the MudMaster name. It shares a lot of the features with it's big brother but has plenty more on top, in some cases it even betters its brother! For example, the barometer function, this watch can show you over 2 days worth of data (the GWG only shows 1 day), much better to see changes in the weather. I also find the thermometer to be better as you don't have direct contact with a metal case back as it has a resin cover. Then of course there is the step tracking function that can record your daily steps ...

Then of course there is the step tracking function that can record your daily steps when using the G-Shock app on your phone. And when you do pair up with your phone a whole new bag of tricks is opened up for you.. from regular timekeeping updates to being able to record your location and then finding your way back using the watch, showing which direction and how far away, without having to take your phone out of your pocket/rucksack. Not to mention how much easier the app makes setting nearly all of the watch functions. I suppose I had better talk about how it looks.. I chose the orange version (1A9ER iirc), it looks stunning, then again all 3 versions do. It fits in nicely with the MudMaster range but slightly smaller than it's big brothers and the carbon fibre bezel looks very swish, the glass is domed which helps with any sunlight reflecting. Lume is pretty good, but should you need more light, the led light is amazing, it is literally the equivalent of shining a torch on the watch face! Fit wise, I have 8 inch wrists and the strap is plenty long, long enough that the tail end can still be held neatly down by the keeper. I barely notice the weight on my wrist, it is very comfortable to wear.tl;dr .... buy it now, it is awesome... oh and delivery was top notch, next working day and VERY well packed! Thanks!
I've had the GG-B100 for two weeks now and I'm more impressed that I ever could have expected. I've worn it to work, the gym and on days out and it has withstood all kinds of impact. The build is robust, the light is extremely powerful for such a small watch and the glow in the dark feature has proven to be useful on several different occasions. Generally, all the functions seem to be quite accurate, including the step counter. The display is visible without fail during the day, but can get a bit difficult to see in darker environments, which the light more than makes up for. My only issue is that it can be a bit uncomfortable to wear for extended periods of time, but that's a small price to pay for a nigh-indestructible watch band. Overall fantastic quality, the ...
