Was given a GW6900 by a friend who didn’t use it anymore, was impressed by the fact it used light to charge and used radio waves to keep spot on time, (last owned a G Shock back in 98) not being a digital watch person I just used it to set my other watches, then I came across this and was impressed so ordered it on Friday, it arrived the next day, wow, what a beauty, the setting was easy as long as you re-read the instructions, and so comfortable due to the resin strap as opposed to plastic as on some ranges, if you want an “any where, any time” watch without the worries of batteries and time settling, this is it. You won’t be disappointed.
