    • Just spectacular!!!
Just stunning, and with that metal band. Got it for a birthday. It's amazing up close in real life, and as big as my Gulf Master. I'm sure it's just as tough too, but it's gonna make a great dress watch.

    • Nice watch but....
Very nice watch. Bigger than I expected. It came with NO english instructions. If you are sending a watch to the UNITED STATES, does it not make sense to put "English" instructions with it? I got all Japanese instructions. Even going to Casio/G shock website was not helpful. I put in the model,,then they wanted a submodel which I do not know. STUPID customer and product service. I found a video online, watched it three times and it took me an hour to set the time on this. I thought it was an atomic clock like my other casio g shock, especially since it costs way more. ... show more

    • The best Gshcok ever, and the best Amazon third party seller ever
Review Image by Emadi
I have owned several g shock models. From Gsteel s version to MTGs. This is the best of them. It is more practical than GSTS version and is as calssy as the MTG. The bluetooth capability makes time syncing very easy. I try to stay away from radio controlled G shocks as I found them to be very unstable. This G shock looks great and works great. It can be your only watch. You can wear it as a sport watch and also as a dress watch. The seller (Japan Treasure factory) did such a great job. They shipped it very fast and it arrived before the delivery estimate date. I highly recommend them. ... show more

    • Best looking and a great G-shock!
Best value ever! cost less than half of my MTG (which I love!). Syncs to smartphone for many features! No Rolex, Apple watch, or other rugged watch even comes close to this great Analog watch, at a great price!
