Probably the best G-shock. It's unfortunate it's only released for the Japanese market, so you have to pay a bit extra to get it imported over to the UK. Getting it imported from America was cheaper than importing is straight from Japan, so I bought it here on Amazon.The watch is linked to a radio signal so that the time is automatically set wherever you are in the world. There is also a solar panel built into the watch so it will charge on its own. I read a review of a guy who has had the same battery in his watch for 17 years so far without changing it.The moon and tide function is very nice, the overall aesthetic is what drew me to it in the first place. I like the gloss, and expect it to dull slighty over time as this will be my daily watch. I like the functions of the watch, especially that I can still see the time when using other functions.
