Love chunky analog watches and this thing is basically perfect. Super stylish in a good nerdy way, love the BT capability, and the always-visible 2nd timezone. Not really anything else I could ask for except better eyesight :)

I bought this watch because it was solar and I could set the time through a phone app. My previous G shock was way too complicated to set and wasn’t getting signal updates. Upon trying to download the app, I realized it was nothing more than a data harvesting app that needed to know too much pertinent information. Then there was a request that they could sell that information! No thank you. The watch cannot be set manually. Turning the stem resulted in erratic behavior from the second hand. very disappointed, I returned it. I’ll stick with my cheap Chinese knock offs. Pull the stem out, turn it one way or the other and then push it back in. The time is set! Simple

Nice lightweight analogue watch.Sits really well on the wrist and is super comfortable.Doesn't have all the bells and whistles but for me still really nice to look at.
Watch has the easiest face to quickly read, one button dual- time swap, very well illuminated night use as well. One of the best color patterns and most comfortable of all my g-shocks (over 15 lol).
This watch is great. Very precise hands and the second hand reminds me of a weather vane which is cool. The color scheme is perfect and it's becoming my most worn watch.
Love the look and the features. Pretty straight forward design. The only thing I think may become an issue is the plastic clasp on the watch band. Feels very thin. No options to replace the band available yet. Hopefully soon. A silicon band with a metal clasp would be ideal
Fantastic watch for the price, have several watches costing much more, but won't be buying any more without checking gshock watches. Looks great on the wrist and can't get over all the functions. Great product casio, if you shop around you can get it 50 quid cheaper.
I miss some of the features of some of the older Gravitymaster watches. For the price, it could be more “Master of G.” A compass, a backlit digital display, maybe even something cool like weather forecasts via the mobile link to the Casio Watches app. It’s very light and looks nice, but it’s merely good instead of great.
A beautiful G-Shock with supreme Read-ability and useful functions. The Tough Solar sold it for me as I always look out for G-Shocks powered by light. A great watch all in all and looks great. The hands are some of the best looking on an analogue. Love it. Thanks.
